• Digital Intelligent High Power AVR / Stabilizer (APR, PRN)

Digital Intelligent High Power AVR / Stabilizer (APR, PRN)

Specially for whole plant power equipment
New Generation Digital Logic Combined Functional Setting. Complete Capacity and Specifications, CE Certified. The Series is designed of built-in multiple functions digital meters, in conjunction of indicators. The equipment is easy in operation. Joining with a number of patents and anti-mistake engineering design. The producing procedure meet international standard, with high quality and long MTBF, the serial equipment are good for all kinds load and sites.
Model : APR PRN three phase series

Digital Display

Easy and Precise Setting

SOVP Device

Digitally display the functions of voltage and frequency of all phases

Press button setting of voltage and frequency of all phases.  Functions are complete and operations are easy

Whether it is switched on or recover from power outage, the Start Over Voltage Protection will always re-start from low voltage, won’t have high voltage output

Multi-Function State Display

Noise Preventing Device

Separated Regulation

All states of various power are displayed in indicator allowing for determine the condition of the AVR clearly

The AVR is installed in extra arc suppressor and noise interference prevention devices

Three phase separate regulators design for attaining precise output

I/P & O/P Wires Protection

Bypass Device

H Class Protection

Wiring fixed, input/output wires well sealed, stable & safety

It allows for bypassing at of protection and maintenance. And when bypassed, the protection functions is still working

With Class H insulation materials transformer

Model No.
