Monitor and control power sources to reliably operate a transfer switch.
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.
Available system type setting: Mains - Generator, Generator - Mains, Mains - Mains;
132x64 LCD with backlight, optional Chinese and English display, push-button operation
Measure and display 2-channel 3 phase voltage, frequency and phase sequence
Display of A power / B power accumulated close time
