PTS Low-Voltage (LV) Manual Break Switch & Isolators

PTS MICROPROCESSOR CONTROLLER

Monitor and control power sources to reliably operate a transfer switch.

PTS-WST-5

OPERATE WITH MAXIMUM EFFICIENCY

The PTS-WST-5 dual power ATS controller is a dual power transfer module that is integrated with configurable functions, automatic measurements, an LCD display and digital communication system.

It combines digitalisation, intelligence and networking to fulfil automated measuring and control processes for lesser artificial operation mistakes. PTS-WST-5 is the ideal product for dual power transfer as it is applicable for non-breaking, one-breaking, and two-breaking switches.

PROVEN SECURITY AND EASE OF USE

PTS-WST-5 series is made with the microprocessor in the core, which can precisely measure 2-channel 3-phase voltages, make correct judgment and control outputs for occurred voltage abnormal (over voltage, under voltage, loss of phase, over frequency, under frequency, reverse phase sequence).

DESIGNED TO PERFORM ACROSS A WIDE RANGE OF APPLICATIONS

PTS-WST-5 features a compact structure, advanced circuits, simple wiring and high reliability that enable it to be used in electrical automatic control system of electric power, telecommunications, petroleum, coal, metallurgy, railways, municipal administration, intelligent building and more.
