616. Standby STB STB terminal
Standby supply (5V, 1A) is provided to ease customer application. Standby supply voltage is functionally
isolated from all other signal terminals and output terminals, and it is always available as long as input power
in the specified voltage range is supplied.
Over Current Protection (OCP) is fold back limit and hiccup mode with automatic recovery.
OCP function operates when the output current exceeds 105% of maximum DC output current of specification. The
outputs will be automatically recovered when the overload condition is canceled. Never operate the unit under over current
or shorted conditions, which may leads damage or insulation failure. OCP setting is fixed and not to be adjusted externally.
The Over Voltage Protection (OVP) is inverter shut down method and manual reset type. OVP function operates
within 105%170%.
When OVP triggers, the output will be shut down. To reset OVP, remove the input of power supply for a few
minutes, and then reinput. In addition, the setting value of OVP is fixed and not adjustable. Never apply higher
voltage externally to the output terminal to avoid unit failure. In case of inductive load, put protective diode in
series to the output power line.
