Programmable DC Power Supplies SK3323/3325

Programmable DC Power Supplies

SK3323/3325

SK3323/3325 has RS232 programmable interface and optional USB interface, supports to output regulated current as preset time. Adopting LIC, three channels of output are supplied. It is of programmable CV/ CC adjustable step. The two working states, CV and CC, can be switched varying with the load. Series/Parallel and independent working selection can be realized.

FEATURES

Three output modes: independent, series and parallel

Timer function to output as preset time

Smart controlled fan, effectively reduce the noise

Keypad locked function to avoid misoperation

Standard RS-232 interface, optional interface USB
