Note: Our company reserves the right to interpret the product as it is constantly updated without further notice and subject to the actual sample.

The chassis is made of aluminium alloy.

The medium frequency voltage doubling circuit, PWM pulse width modulation technology and high power IGBT device are used.

With large voltage feedback, the output voltage stability is high and the ripple coefficient is less than 3%.

Full range smooth voltage regulation, fine voltage regulation accuracy (<1%), stability (<1.5%), voltage error (+1.5%+2 words), current error (+1.5%+2 words).

Boost potentiometer zero boost.

0.75 UDC1mA function button, convenient for zinc oxide arrester test, accuracy (+3%+2 words).

Overvoltage protection is set by dialing code, which is clear at a glance with an error of (+1%).

The double pressure is made of new material, which is light and strong. Exterior coated with special insulation material, good electrical performance, strong moisture-proof ability.

HYG products meet DL/T848.1-2004 technical requirements, and through the type test of the Electrical Equipment Quality Inspection and Testing Center of the Ministry of Electricity, strictly implement the enterprise standard.
