Voltage failure indication
When the load is under OVP or reverse protection condition, pin (VF, GND) will
output low level signal.
Current monitoring
Current monitoring terminal will output 0-10V analog signal to accordingly on
behalf of 0 - full range of input current. You can connect an external voltmeter or
an oscilloscope to display the input current's changing.
Digital I/O
The digital I/O ports are the DI and DO in the module's rear panel terminals and
are used only for remote control. Pin (DO, GND) digital output terminal can
output TTL high/low level. It is a universal output terminal and can be used in
controlling an external instrument, for example, the relay used in power testing.
(DI, GND) is used to detect the external level state.
External analogue control
You can control the voltage and current setting of the electronic load by the
analogue terminals: pin Ext_PRG+ and pin Ext_PRG-. 0-10V adjustable
analogue simulate the 0-fullscale to regulate the input voltage and current of
the electronic load(10V indicate the full range of load voltage or current value）.
