2.WYJ1730SL 30A/WYJ1730SL 40A & WYJ1730SC 30A/WYJ1730SC 40A Large Power D.C. Regulated Power Supply Feature 

Single-way large power D.C. Regulated power supply

Max. output power up to 1200W

Reliable protection functions of over current, over thermal and circuit

8 hours continuously working

The value of voltage and current of WYJ 1730SL is displayed by three digits

The value of voltage current of WYJ 1730SC is displayed by meters

3.WYJ1721SL/WYJ1731SL & WYJ1751SC/WYJ1761SL Feature 

Two-way output

Two numeral tubs show the value of output voltage and current separately through the choice switch.

The regulated voltage and current can be switched automatically and showed by luminous tube.

The two-way output voltage can be serial-shunt operation as per requirement, while in serial and shunt operation ,one of the main

power can follow the voltage or current(shunt).

It adopts the mode of protection of current limitation, which can be adjusted as per requirement.

It can add up to 5V/3A fixed voltage output as the users’ requirements.

Full plastic frame, novel appearance.
