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 supp
ly 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
requirem
ent about remote ON/OFF control ( e.g. reverse control logic, insulation control etc.), please contact
TDK-Lambda Corporation.
