1.WYJ D.C. Regulated Power Supply
The WYJ series D.C. Regulated power supply is the one whose output voltage is variable. They have the functions of continuous adjustment output voltage and fixed output to be chosen as per requirements. The circuit consists of integrated circuit and power amplifier, with single-way output and multi-ways independent output. The circuit has functions of high steady in capability, reliability in characteristic, steady in output voltage, small size novel appearance, suitable for scientific research institutes, manufactories, electric appliance serices and so on.

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.
