6.1 Examples for the analogue interface
6.1.1 Remotely switching output on / off
Input : REM-SB (8)
The input can be used to switch off the device output
at any time. After this, switching it on again is only
possible by releasing the contact or switch.
The contact/switch on pin 8 overrides the pushbutton
„Output On/Off“. It means, if pin 8 „forces“ the output
to be off, it can not be switched on by the pushbutton.
Switching to remote control by pin 7 is not required.
During remote control, this input REM-SB is also
used to acknowledge and reset an OVP error by
pulling the pin to LOW (=off).
6.1.2 Monitoring voltage and current
Analogue outputs: VMON (4) and CMON (5)
The analogue monitoring outputs VMON and CMON
put out 0...10V, which corresponds to 0...100% of
the actual values of voltage and current.
Measuring those output should be done with high-
impedance meters or a high-impedance input of a
measuring circuit, because those outputs can only
drive limited current.
