The Velleman PS3005D is a 1-channel programmable power supply (0-30V/0-5A) with both USB and RS232 connectivity.
It is probably a rebadged Korad KA3005P.
See Velleman PS3005D/Info for more details (such as lsusb -v output) about the device.

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 is then responded by the power supply.
During a PC connection, the front control buttons and the scrollwheel are blocked.
| Request | Example output | Remarks |
|---|---|---|

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) |

| 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. |
| OVP1 | (none) | Enable the "Over Voltage Protection", the PS will switch off the output when the voltage raises above the actual level. |
| OVP0 | (none) | Disable the "Over Voltage Protection". |
| OCP1 | (none) | Enable the "Over Current Protection", the PS will switch off the output when the current raises above the actual level. |
| OCP0 | (none) | Disable the "Over Current Protection". |
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.
