Safety Specification General information Ericsson Power Modules DC/DC converters and DC/DC regulators are designed in accordance with safety standards IEC/EN/UL60950, Safety of Information Technology Equipment. IEC/EN/UL60950 contains requirements to prevent injury or damage due to the following hazards: Electrical shock Energy hazards Fire Mechanical and heat hazards Radiation hazards Chemical hazards On-board DC-DC converters and DC/DC regulators are defined as component power supplies. As components they cannot fully comply with the provisions of any Safety requirements without "Conditions of Acceptability". Clearance between conductors and between conductive parts of the component power supply and conductors on the board in the final product must meet the applicable Safety requirements. Certain conditions of acceptability apply for component power supplies with limited stand-off (see Mechanical Information for further information). It is the responsibility of the installer to ensure that the final product housing these components complies with the requirements of all applicable Safety standards and Directives for the final product. Component power supplies for general use should comply with the requirements in IEC60950, EN60950 and UL60950 "Safety of information technology equipment". There are other more product related standards, e.g. IEEE802.3af "Ethernet LAN/MAN Data terminal equipment power", and ETS300132-2 "Power supply interface at the input to telecommunications equipment; part 2: DC", but all of these standards are based on IEC/EN/UL60950 with regards to safety. Ericsson Power Modules DC/DC converters and DC/DC regulators are UL60950 recognized and certified in accordance with EN60950. The flammability rating for all construction parts of the products meets requirements for V-0 class material according to IEC 60695-11-10. The products should be installed in the end-use equipment, in accordance with the requirements of the ultimate application. Normally the output of the DC/DC converter is considered as SELV (Safety Extra Low Voltage) and the input source must be isolated by minimum Double or Reinforced Insulation from the primary circuit (AC mains) in Isolated DC/DC converters It is recommended that a slow blow fuse with a rating twice the maximum input current per selected product be used at the input of each DC/DC converter. If an input filter is used in the circuit the fuse should be placed in front of the input filter. In the rare event of a component problem in the input filter or in the DC/DC converter that imposes a short circuit on the input source, this fuse will provide the following functions: Isolate the faulty DC/DC converter from the input power source so as not to affect the operation of other parts of the system. Protect the distribution wiring from excessive current and power loss thus preventing hazardous overheating. The galvanic isolation is verified in an electric strength test. The test voltage (Viso) between input and output is 1500 Vdc or 2250 Vdc for 60 seconds (refer to product specification). Leakage current is less than 1 A at nominal input voltage. 24 V DC systems The input voltage to the DC/DC converter is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions. 48 and 60 V DC systems If the input voltage to the DC/DC converter is 75 Vdc or less, then the output remains SELV (Safety Extra Low Voltage) under normal and abnormal operating conditions. Single fault testing in the input power supply circuit should be performed with the DC/DC converter connected to demonstrate that the input voltage does not exceed 75 Vdc. If the input power source circuit is a DC power system, the source may be treated as a TNV2 circuit and testing has demonstrated compliance with SELV limits and isolation requirements equivalent to Basic Insulation in accordance with IEC/EN/UL60950. Non-isolated DC/DC regulators The input voltage to the DC/DC regulator is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions.

Conducted EMI Input terminal value (typ) Test set-up Layout recommendation The radiated EMI performance of the DC/DC converter will depend on the PCB layout and ground layer design. It is also important to consider the stand-off of the DC/DC converter. With regards to the isolation requirements avoid placing a conductor which is connected to the primary side below the DC/DC converter. If a ground layer is used, it should be connected to the output of the DC/DC converter and the equipment ground or chassis. EMI without filter @ Vi = 48 V, max Io.

The input voltage range is 45 to 75Vdc for PKUC 4106C. The absolute maximum continuous input voltage is 80 Vdc. Turn-off Input Voltage The DC/DC converters monitor the input voltage and will turn on and turn off at predetermined levels. The minimum hysteresis between turn on and turn off input voltage is 1 V. Remote Control (RC) The products are fitted with a remote control function referenced to the primary negative input connection (- In), with negative and positive logic options available. The RC function allows the converter to be turned on/off by an external device like a semiconductor or mechanical switch. The RC pin has an internal pull up resistor to + In. The maximum required sink current is 0.4 mA. When the RC pin is left open, the voltage generated on the RC pin is max 5 V. The maximum allowable leakage current of the switch is 50 A. With "negative logic" the converter will turn on when the input voltage is applied with the RC connected to the - In. Turn off is achieved by leaving the RC pin open, or connected to a voltage higher than 5 V referenced to -In. The second option is "positive logic" remote control, which can be ordered by adding the suffix "P" to the end of the part number. The converter will turn on when the input voltage is applied with the RC pin open. Turn off is achieved by connecting the RC pin to the - In. To ensure safe turn off the voltage difference between RC pin and the - In pin shall be less than 1 V. The converter will restart automatically when this connection is opened. Rev Reference EN/LZT 146 447 R1D B 12 April 2013 (c) Ericsson AB When powering loads with significant dynamic current requirements, the voltage regulation at the point of load can be improved by addition of decoupling capacitors at the load. The most effective technique is to locate low ESR ceramic and electrolytic capacitors as close to the load as possible, using several parallel capacitors to lower the effective ESR. The ceramic capacitors will handle high-frequency dynamic load changes while the electrolytic capacitors are used to handle low frequency dynamic load changes. Ceramic capacitors will also reduce any high frequency noise at the load. It is equally important to use low resistance and low inductance PCB layouts and cabling. For further information please contact your local Ericsson Power Modules representative. Parallel Operation Two converters may be paralleled for redundancy (1+1) if the total power is equal or less than POmax for one unit. To secure the function oring diodes may be used. Pre-bias Start-up These products has pre-bias start up functionality and will not sink current during start up if a pre-bias source is present at the output terminal up to the min-value of output voltage tolerance band, i.e. 4.5 V for a 5 V version and 10.8 V for a 12 V version. Nor will there be any under or over shoot. See Design Note 026 for detailed information. Over Temperature Protection (OTP) The converters are protected from thermal overload by an internal over temperature shutdown circuit. When Tref as defined in thermal consideration section exceeds 135C the converter will shut down. The DC/DC converter will resume normal operation automatically when the temperature has dropped approx 22C below the temperature threshold. Over Voltage Protection (OVP) The converters have output over voltage protection that will clamp the output voltage to a continous fixed level. After removal of the over voltage condition the converter will resume to normal operation automatically. Input and Output Impedance Over Current Protection (OCP) The impedance of both the input source and the load will interact with the impedance of the DC/DC converter. It is important that the input source has low characteristic impedance. The converters are designed for stable operation without external capacitors connected to the output. The performance in some applications can be enhanced by addition of external capacitance as described under External Decoupling Capacitors. If the input voltage source contains significant inductance, the addition of a 100 F capacitor across the input of the converter will ensure stable operation. The capacitor is not required when powering the DC/DC converter from an input source with an inductance below 10 H. The converters include current limiting circuitry for protection at continuous overload. The output voltage will decrease towards zero for output currents in excess of max output current (max IO). The DC/DC converter will resume normal operation after removal of the overload. The load distribution should be designed for the maximum output short circuit current specified.

Cooling is achieved mainly by conduction, from the pins to the host board, and convection, which is dependent on the airflow across the converter. Increased airflow enhances the cooling of the converter. The Output Current Derating graph found in the Output section for each model provides the available output current vs. ambient air temperature and air velocity at Vin = 53 V. The DC/DC converter is tested on a 254 x 254 mm, 35 m (1 oz), 16-layer test board mounted vertically in a wind tunnel with a cross-section of 305 x 305 mm. Proper cooling of the DC/DC converter can be verified by measuring the temperature at reference point. The temperature at this position should not exceed the max values provided in the table below. See Design Note 019 for further information.

Temperatures above maximum Tref are not allowed and may cause degradation or permanent damage to the product. Tref is also used to define the temperature range for normal operating conditions. Tref is defined by the design and used to guarantee safety margins, proper operation and high reliability of the module.

The reflow profile should be optimised to avoid excessive heating of the product. It is recommended to have a sufficiently extended preheat time to ensure an even temperature across the host PWB and it is also recommended to minimize the time in reflow. A no-clean flux is recommended to avoid entrapment of cleaning fluids in cavities inside the product or between the product and the host board, since cleaning residues may affect long time reliability and isolation voltage. 2011-12-05 Rev Reference EN/LZT 146 447 R1D A Template rev.
