Our voltage regulators are setting new standards for quality – in design, manufacturing and testing.
We have the core technologies and all main parts are manufactured by ourselves, for compensation transformer processing equipment, please click the SG Dry Type Transformers product details.
Compact design, save your installation space.
Before leaving the LINGFRAN factory, every automatic voltage stabilizer/regulator must pass a series of rigorous tests, performed with advanced equipment, on a range of measurements.
(1) Appearance – visual check.
(2) Input voltage regulation range, output voltage and output accuracy.
(3) Insulation resistance and withstand voltage strength .
(4) Protection Function: Over/under voltage, manual bypass, limit switch.
Below are part of our testing instrument.
