The Korad KAxxxxP series are 1 channel switch-mode programmable power supplies with USB/serial connectivity.
The devices are also sold as rebranded versions by e.g. Velleman.
Devices
| Korad | Velleman OEM | Voltage range | Current range | Power |
|---|---|---|---|---|
| ? | Velleman PS3005D | 0-30 V | 0-5 A | 150 W |
| ? | Velleman LABPS3005D | 0-30 V | 0-5 A | 150 W |
Protocol
The protocol is serial or serial-over-USB, 9600/8N1, (almost fully) ASCII based. No line termination, CRC or checksum characters are used. The PC sends a request string which the power supply then responds to.
During a PC connection, the front control buttons and the scrollwheel are blocked.
| Request | Example output | Remarks |
|---|---|---|
| *IDN? | VELLEMANPS3005DV2.0 KORADKA3005PV2.0 |
Request identification from device. |
| STATUS? | (byte) | Request the actual status. The output is a single byte with the actual status encoded in bits. At least the Velleman PS3005D V2.0 is a bit buggy here. The only reliable bits are: 0x40 (Output mode: 1:on, 0:off), 0x20 (OVP and/or OCP mode: 1:on, 0:off) and 0x01 (CV/CC mode: 1:CV, 0:CC). |
| VSET1? | 12.34 | Request the voltage as set by the user. |

| VOUT1? | 12.34 | Request the actual voltage output. |
| ISET1? | 0.125 | Request the current as set by the user. |
| ISET1:0.125 | (none) | Set the maximum output current. |
| IOUT1? | 0.125 | Request the actual output current. |
| OUT1 | (none) | Enable the power output. |
| OUT0 | (none) | Disable the power output. |

| SAV1 | (none) | Saves voltage and current limits to memory, 1 to 5 (from Velleman protocol v2.0 documentation). |
Remarks:
- The digit 1 in the V... and I... requests indicates the values are meant for channel one. In future (or "higher"?) models this may be two for a second channel and so on.
- Voltage ("00.00" to "31.00" V) and current ("0.000" to "5.100" A) output values have a fixed length with fixed dot position. The values won't become negative.
- ISET1? replies sixth byte on many models (all?) which is sixth character from *IDN? reply if *IDN? is queried before during same power cycle. This byte is read and discarded by sigrok.
