3.9 Auxiliary Output
3.10 Remote ON/OFF Control - Whole Power System
◎
Built-in 12V/0.1A auxiliary output that can be used as the voltage source of remote ON/OFF control application for individual
output modules or the whole modular system. Please refer to figure 3-2 and 3-3 for wiring methods.
◎
Built-in remote ON/OFF control circuit for the whole power system.
◎
The remote control circuit (+RC and -RC) has electric isolation from V and V .
in out
◎
When there's a 4~12V voltage difference or open circuit bRC & -RC, the whole power system will be turned off. The power
supply will be turned on if the voltage difference bRC & -RC is less than 0.8V or short circuit. ( The whole power system will
have no output if the shorting connector is not assembled bRC & -RC on CN4.)
◎
The auxiliary output on the power supply can be used as the external control source of the remote ON/OFF control function.
Please refer to figure 3.2 for connecting methods.
3.11 Remote ON/OFF Control - Output Modules
◎
Built-in remote ON/OFF control circuit for each output module. All output modules can be turned ON/OFF independently by using
the remote ON/OFF control function.
◎
The remote control circuit (+RC and -RC) has electric isolation from V and V .

◎
The auxiliary output on the power supply can be used as the external control source of the remote ON/OFF control function on each
output module. Please refer to figure 3.3 for connecting methods.
◎
When there's a 4~12V voltage difference bRC & -RC, the output module will be turned off. The power supply will be turned
on if the voltage difference bRC & -RC is less than 0.8V or open circuit.

3.12 Remote Margin V Program
/ -
◎
Remote Margin / V- Program is available for MS-210 and MS-360 to fine tune the output voltage. Hereunder is the instruction,
assuming no voltage adjustment is applied via the built-in potentiometer.
(1) Connecting PIN CN7-6 with PIN CN7-8 will increase the output voltage by approximately 5% of the rated voltage.
