Table 3-2. J2 Connector Signals
Pin Signal Description
1 CV STATUS On when the RMX programmable power supply is in
CV mode. (open-collector output from a photocoupler)
1
2 CC STATUS On when the RMX programmable power supply is in
CC mode. (open-collector output from a photocoupler)
1
3 ALM STATUS On when a protection function (OVP/OVP2/ OCP/ OHP/
OHP2/ FAN/ SEN/ACAC-FAIL) is activated.
(output through an open-collector photocoupler)
1
4 PWR ON STATUS Outputs a low level signal when power is turned on
(output through an open-collector photocoupler)
1
5 OUT ON STATUS On when output is on (output through an open-collector
photocoupler)
1
6 to 9 STATUS COM Status signal common for pins 1 to 5
2
.
The above signal output circuit is protected with reinforced insulation from the MAINS.
1
Open collector output: Maximum voltage of 30 V and maximum current of 8 mA.
2
That status common is floating (isolation voltage of 60 V or less), it is isolated from the control circuit.
