4-11. Standby Power
A fixed 5V standby power is provided through STBY+ and STBY- of CN61. And its maximum output current is 0.6A at convection cooling
and 1A at forced air cooling. For CUS200M standard model, STBY- and V- are shorted together internally. If you want an insulated standby
mode power, please contact TDK-Lambda Corporation.
4-12. DC_OK Signal
DC_OK signal shows "High" level (4.5V~5V) to indicate power supply operating normal, and can source maximum 2mA current.
When power supply stops operating, the signal will turn to "Low" level (0V~0.5V), and the maximum sink current is 1mA.
4-13. Remote ON/OFF Control
R- is for remote ON/OFF control function. Usually, a switch (relay, transistor etc.) is connected between R- and STBY- for remote ON/OFF
control. Close the switch can shut down the main output without turning off the AC input. For CUS200M standard model, R+ is connected to
STBY+ internally, not for customer using. If you have special requirement about remote ON/OFF control ( e.g. reverse control logic,
insulation control etc.), please contact TDK-Lambda Corporation.
5. Mounting Directions
5-1. Output Derating according to the Mounting Direction
Recommended standard mounting direction is (A). Mounting direction (B)-(E) are also possible. Refer to the output derating below.
Load (%) of derating curve indicates output power.
5-2. Output Derating
Make sure that the specified temperature range is maintained.
