Pins Description
1 RS-232 TXD pin for transmitting data.
2 RS-232 RXD pin for receiving data.
3 RS-232 DGND pin for grounding.
4 Ground terminal, that is, the negative terminal of pin 5 to pin
10.
5 Voltage monitoring terminal. It can output a voltage of 0 to
10V to monitor the output voltage from 0 to full scale.
6 Current monitoring terminal.
It can output a voltage of 0 to 10V to monitor the output cur-
rent from 0 to full scale output current.
7 Reference voltage (10V) test terminal. The accuracy is
0.03%. You can use a multimeter to measure this pin. When
the output voltage of the pin is in the range of 10±0.03%*10, it
