PERFORMANCE DATA
EMI CONSIDERATIONS
For optimum EMI performance, the power supply should be mounted to a metal plate grounded to all 4 mounting holes of the power supply. To comply with
safety standards, this plate must be properly grounded to protective earth (see mechanical dimension notes). Pre-compliance testing has shown that a stand-
alone power supply complies with EN55022 class A radiated emissions. Radiated emission results vary with system enclosure and cable routing paths.
SAFETY CONSIDERATIONS
1. This power supply is a component level power supply intended for use in Class I or Class II applications. Secondary ground traces need to be suit-
ably isolated from primary ground traces when used in class II applications.
2. When the power supply is used in Class II equipment, all ground traces and components connected to the primary side are considered primary for
spacing and insulation considerations.

CONTROL SIGNAL
Parameter Conditions
V1 Remote
This signal must be pulled low state (maximum of 0.2Vdc, sink current >15mA) to V2 return terminal to turn on the main V1
output. The power supply shall include an internal pull up resistor to an internal 12Vdc to disable the main V1 output if the
signal is left open. The power supply shall not pull this signal down if there is no AC input. The open circuit voltage present
when in the “open” state shall not exceed 15Vdc.
The AUX output is independent of the V1 remote signal.

Forced Air Cooling
System thermal management is critical to the performance and reliability of the MVAC series power supplies. Performance derating curves are provided which
can be used as a guideline for what can be achieved in a system confi guration with controlled airfl ow at various input voltage conditions.
The air fl ow curves are generated using an AMCA 210-99 and ASHRAE 51-1999 compliant wind tunnel with heated inlet air and a controlled CFM providing a
duct test section having a calculated average LFM. A correlation between the test setup and the actual system environment is paramount to understanding what
can be achieved in an actual system. In a power supply of this density, cooling air moving both through the unit as well as around the unit strongly infl uences
local temperatures. The wind tunnel test setup was constructed to produce a fl ow with a slight back pressure to induce both fl ow conditions by providing a small
gap between the power supply and duct walls of 0.5” (13mm). The optimal and characterized airfl ow direction is from the input connector to the output connec-
tor (see diagram below). The P-Q fl ow curve for this test setup is also shown below.
