| PIN No | Signal name | Description |
|---|---|---|
| 1 | STATUS COM | Status signal common for pins 2, 3, and 14 to 16. |
| 2 | CV STATUS | On when the PWX series is in CV mode (open-collector output from a photocoupler).*1 |
| 3 | CC STATUS | On when the PWX series is in CC mode (open-collector output from a photocoupler).*1 |
| 4 | N.C. | Not connected. |
| 5 | ALM CLR | Alarm clear terminal. Alarms are cleared when a low TTL level signal is applied to this terminal. |
| 6 | SHUT DOWN | Output shutdown control terminal. The output is turned off when a low TTL level signal is applied to this terminal. |
| 7 | PRL IN- | Negative input terminal for master-slave parallel operation. |
| 8 | PRL IN+ | Positive input terminal for master-slave parallel operation. |
| 9 | PRL COMP IN | Correction signal input terminal for master-slave parallel operation. |
| 10 | A COM | External signal common for pins 5 to 9, 11 to 13, 20 to 22, 24, and 25. During remote sensing, this is the negative electrode (-S) of sensing input. When remote sensing is not being performed, this is connected to the negative output. |
| 11 | PRL OUT+ | Positive electrode output terminal for master-slave parallel operation. |
| 12 | PRL COMP OUT | Correction signal output terminal during Master-slave parallel operation |
| 13 | I SUM | Current signal terminal for master-slave parallel operation. |
| 14 | ALM STATUS | On when a protection function (OVP, OCP, OHP, FAN, SEN, or AC_FAIL) has been activated or when an output shutdown signal is being applied (output through an open-collector photocoupler).*1 |
| 15 | PWR ON STATUS | Outputs a low level signal when power is turned on (CF11: 0) or when power is turned off (CF11: 1; output through an open-collector photocoupler).*1 |
| 16 | OUT ON STATUS | On when output is on. (CF11: 1; output through an open-collector photocoupler).*1 |
| 17 | N.C. | Not connected. |
| 18 | OUT ON/OFF CONT | Output on/off terminal. On (or off) when a low (or high) TTL level signal is applied. |
| 19 | A COM | External signal common for pins 5 to 9, 11 to 13, 20 to 22, 24, and 25. During remote sensing, this is the negative electrode (-S) of sensing input. When remote sensing is not being performed, this is connected to the negative output. |
| 20 | REF OUT | External resistance control terminal 5.25 V (CF07: Lo) or 10.5 V (CF07: Hi). |
| 21 | I PGM | Terminal used to control the output current with an external voltage or external resistance. 0 V to 5 V; 0 % to 100 % of the rated output current (CF07: Lo). 0 V to 10 V; 0 % to 100 % of the rated output current (CF07: Hi). |
| 22 | V PGM | Terminal used to control the output voltage with an external voltage or external resistance. 0 V to 5 V; 0 % to 100 % of the rated output voltage (CF07: Lo). 0 V to 10 V; 0 % to 100 % of the rated output voltage (CF07: Hi). |
| 23 | A COM | External signal common for pins 5 to 9, 11 to 13, 20 to 22, 24, and 25. During remote sensing, this is the negative electrode (-S) of sensing input. When remote sensing is not being performed, this is connected to the negative output. |
| 24 | I MON | Output current 0 % to 100 % of the rated output current is generated as a voltage between 0 V and 5 V (CF08: Lo) or a voltage between 0 V and 10 V (CF08: Hi). |
| 25 | V MON | Output voltage monitor 0 % to 100 % of the rated output voltage is generated as a voltage between 0 V and 5 V (CF08: Lo) or a voltage between 0 V and 10 V (CF08: Hi). |
*1 Open collector output: Maximum voltage of 30 V and maximum current of 8 mA.
The status common is floating (isolation voltage of 60 V or less), it is isolated from the
control circuit.
