Serial Commands for KIPRIM DC310S Voltage/Current Supply

I recently purchased a KIPRIM Power Supply DC310S and reverse engineered the following commands for USB serial control.

Feel free to contribute additional commands via pull request.

EDIT: It appears to be a rebranded version of OWON SPE3103. A documentation of serial commands is available.

Serial Connection Settings

Setting	Value
baud rate	115200
data bits	8
parity bit	none
stop bit	1

Read/Get Commands

Get commands are tailed with a line feed (0x0a). While the official software appears to apply upper-case for the first three letters, commands appear to be case insensitive.

Returns are ASCII tailed with CR LF (0x0d 0x0a).

Invalid commands appear to return ERR.

Command	Return	Description
*idn?	KIPRIM,<model, eg.DC310S>,<serial no.>,FV:Vx.x.x	get manufacturer, model, serial no, firmware version
output?	ON or OFF	get if power supply is active
measure:current?	(x)x.xxx	get measured current
measure:voltage?	(x)x.xxx	get measured voltage
current?	(x)x.xxx	get set current
voltage?	(x)x.xxx	get set voltage
current:limit? curr:lim?	(x)x.xxx	get measured current
voltage:limit? volt:lim?	(x)x.xxx	get measured voltage

Write/Set Commands

Get commands are tailed with a line feed (0x0a). While the official software appears to apply upper-case for the first three letters, commands appear to be case insensitive.

ToDo: Not sure if there is any return for valid/invalid set commands. At the moment, I don't see any.

Command	Description
output <0/1>	set power supply off/on
current (x)x.xxx	set current
voltage (x)x.xxx	set voltage
current:limit (x)x.xxx	set current limit
voltage:limit (x)x.xxx	set voltage limit

Untested commands from OWON pdf (TODO)
