Explanation of Functions and Precautions 3-1. Input Voltage Range Input voltage range is single phase 85 ~ 265VAC ( 47 ~ 63Hz ) or 120 ~370VDC-. Input voltage which is out of specification may cause unit damage. For cases where conformance to various safety spec(UL,CSA,EN) are re- quired, input voltage range of application for safety 100 ~ 240VAC ( 50/60Hz ). 3-2. Output Voltage Range V.ADS trimmer ( VR51, VR&1 ) can adjust the output voltage of V1 and V4 within the range. To turn the trim- mer clockwise, the output voltage will be increased. Output voltage range of V1 is within 5 ~ 5.25V, V4 is following range. Note over voltage protectian (OVP ) function may trigger if the output voltage is increased excessively. 4 Vol A: 5223; 2.0V ~ 3.63V 5225, 2.0V~5.25V 5222; 11.4V~12.6V 5224, 22. 8V ~25.2V 3-3. Inrush Current This series has used Power Thermistor to protect the cir- cuit from Inrush Current. Please carefully select input switch and fuse in cases of the high temperature and re- input the power. 3-4. Wattbox This series designed as a WATTBOX. You are flexibly adjust output power of each channel within the limit of the total allowable output power in specification. Wrota,2 Wy + Wy2 + Wy3 + Wa Wy: Less than maximum V1 output power. Wyz: Less than maximum V2 output power. Wy3: Less than maximum V3 output power. Wy: Less than maximum V4 output power. 3-5. Minimum output Current The output voltage of all channel is stabilized when minimum output current of V1 is more than 12% of maximum output current. Note all channel may not when V1 has no load. a 3-6, Over Voltage Protection ( OVP ) The OVP function ( Inverter shut down method, manual reset type ) built into each channel. (OVP function at V2 and V3 is total voltage detection method.) When OVP of each channel triggers, the all outputs will be shut down. The input shall be removed for a few minutes, and then re-input for recovery of the output to recover. OVP set- ting shall be fixed and not to be adjusted externally. 3-7. Over Current Protection (OCP ) Total & constant current limiting, automatic recovery. OCP function operates when the total maximum output power exceeds 102% of total allowable peak output power on specification. The output will be automatically recovered when the overload condition is canceled. Also, this unit employs total current detection for OCP. Therefore, take note that the unit might be damaged be- cause OCP may not operate even if each channel exceeds each maximum output current specification. Never operate the unit under over current or shorted con- ditions over 30 seconds which could result in damage, insulation failure, smoking or burning. 3-8. Output Ripple & Noise The standard specification for maximum ripple value is measured according to measurement circuit specified by EIAJ-RC913 1. When load lines are longer, ripple will becomes larger. In this case, electrolytic capacitor, film capacitor, etc. might be necessary to use across the load terminal. The output ripple cannot be measure accurately if the probe ground lead of oscilloscope is too long. 150mm AWC18 p 1.5m 509 Cable +5V + N\ A RLL; TRI Teles Re / jes (cy U_b) Oscillascope Bandwidth + 100MHz ot -Cv of} En [Le G3 CT ile(2X) The number of terminals are different by model.

Peak Output Current For ZWQ series, relation between maximum output cur- rent (Convection cooling) and peak output current must satisfy formulas below. Also operating time at peak out- put current(T ) should be less than 10sec, piriod(T) should be more than 1 0msec. (Duty<0.35) Ip | -t----p---4---- in 0A T Ipxt Tav > Im = Pp T 7 I jd _.

Remote ON/OFF Control Remote ON/OFF control(CN2,CN52) function 1s avail- able. Using this function allows the user to turn the all outputs on and off without having to turn the AC input on and off. Remote ON/OFF control can be used by fol- lowing 2 modes When shipping, CN2 is installed with a short connector. When use this function, must be put off a short connector. However, for Cover & Chassis type (ZWQ/A), can not be used. Primary side A connector( CN2 ) for ON/OFF control is provided in the Primary Circuit. When using CN2, safety standard requirements should be considered in application design or choice of switch, relay or connector. In particular: - (1) Basic insulation must be provided between the ON/OFF control circuit and earth. (2) Reinforced insulation must be provided between the ON/OFF control circuit and any secondary circuit or accessible part. (3) Wiring must be drawn to avoid damage to the insula- tion of the wire or sleeving. Terminal conditon Output Condition Connector(CN2) Short ON Connector(CN2) Open OFF Secondary side When using Secondary side ON/OFF Control, put off a jumper J1 at CN2. It is controlled by the voltage applied to +R and R at CNS3. This circuit never connect in the Primary (input ) side. And this circuit is isolated from the output by a photocoupler.The control mode is shown below.

S5VDC No required 12.5.-24.5VDC 1.5kQ 4. Isolation Test / Withstand Voltage 4-1 Isolation Test Isolation resistance between output and FG ( chassis ) shall be more than 100MQ at SOOVDC. For safety op- eration, voltage setting of DC isolation tester must be done before the test. Ensure that the unit is fully dis- charged after the test. Output ~ FG ( chassis ) Isoletion Tester 5OOVDC, ~OCMQ or more 4-2. Withstand Voltage This series is designed to withstand 3.0kVAC between input and output, 2.0k VAC between input and FG (chassis ) and 500VAC between output and the FG ( chassis ) cach for 1 minute. When testing withstand voltage, set current limit of the withstand voltage test equipment to 20mA ( Output - FG ( chassis ) : 100mA ). The applicd voltagc must be gradually increased from zero to the testing value and then gradually decreased for shut down. When timer is used, the power supply may be damaged by high impulse voltage at timer switch on and off. Connect input and output as follows.

Mounting Method PCB type Please use the mounting hole as: ZWQ80 : Sholes of 63.5 ZWQ130 : 4holes of 63.5 and insert the spacer (MAX 6.0)of height over 8mm to lift the unit. Also use all mounting holes for the unit in- stallation. The vibration spec is the value when the unit is raised by 8mm spacers.

Wiring Method @ The output load line and input line shall be separated and twisted to improve noise sensitivity. @ Use all lines as thick and short as possible to make lower impedance. @ Noise can be eliminated by attaching a capacitor to the load terminals. @ For safety and EMI considerations, connect FG terminal of input connector and mountable FG of ZWQ series to mounting set ground terminal at equipment. @ Select the wire materials to adapt the connector as follow. INPUT ; ZWQ80/130 +--+: AWG#22-#18 OUTPUT; ZWQ80/130 -+++ AWG#22-#18 15 7, External Fuse Rating Refer to the following fuse rating when selecting the ex- ternal fuses that are to be used on input line. Surge cur- rent flows when line turns on. Use slow-blow fuse or time-lug type fuse. Do not use fast-blow fuse. Fuse rat- ing is specified by in-rush current value at line turn-on. Do not select the fuse according to input current (rms.) values under the actual load condition. ZWOQ80 : ZWQ130: 3.15A 5.0A 8. Before concluding that the unit is at fault... Before concluding that the unit is at fault, make the fol- lowing checks. Check if the rated input voltage is connected. Check if the wiring of input and output is correct @ Check if the wire material is not too thin. Check if the output voltage control ( V.ADJ ) is properly adjusted, @ Ifyou use function of the Remote ON/OFF control, Check if the Remote ON/OFF control connector is not opened. Check if the output current and output wattage dose not over specification. @ Check if the output current of CH1 is more than 12% of maximum output current. Audible noise can be heard during Dynamic-Load operation. @ Audible noise can be heard when input voltage waveform is not sinusoidal wave. 9.
