5-1-6. OUTPUT VOLTAGE & CURRENT MONITORING
When the DC power is using to an external monitor, the pin assignments as follows:
APG
Signal Name
Description
P24
Analog common
Analog programming signal control ground
P20
V MONITOR
Analog monitor 0~10Vdc for proportional output voltage
measurement
P22
A MONITOR
Analog monitor 0~10Vdc for proportional output current
measurement
To short P24, P20 and P22 will damage the DC power.
Output resistance: Approx. 100Ω; the maximum output current: Approx. 10mA
5-1-7. RECALL FUNCTION
To enable or disable recall by short or open the P1 and P2 (Please refer to 8-4 RECALL setting)
5-1-8. OUTPUT STATUS MONITORING
To connect P8, P9, P10, P11, P12 from APG on the rear panel
APG
Signal Name
Description
P8
State common
Common for status signals from P9~ P12
*Note 1
P9
ALARM State
Pin 9- Pin 8 short when the OVP, OCP or OTP trips or when a shutdown signal
is applied (open collector controlled by a photo coupler)
* Note 1
P10
ON/OFF State
Pin 10- Pin 8 short when the output is on (open collector controlled by a photo coupler)
*
Note 1
P11
CC State
Pin 11- Pin 8 short during CC operation (open collector controlled by a photo coupler)
*
Note 1
P12
CV State
Pin 12- Pin 8 short during CV operation (open collector controlled by a photo coupler)
*Note 1
Note 1: Open collector output: Maximum voltage of 30 V and maximum current of 8 mA.
