Pre-shipping Test

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 voltage, under voltage, short circuit.
