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
*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.
VSET1:12.34	(none)	Set the maximum output voltage.
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.
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:

1. 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.
2. 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.
