Designed for Ease of Use and Installation
Mounting and using a microprocessor controller should be a frictionless experience. Apart from its push-button operation, PTS-WST-8B, offers a modular design, self-extinguishing ABS plastic shell, pluggable terminal, built-in mounting and compact structure for easy installation.

Remote Control for Enhanced Safety
The Dual-RS485 isolated communication interface includes remote controlling, measuring, communication and regulating functions by the ModBus-RTU communication protocol, allowing you to remotely control both the genset and the breaker.

Features

Ability to learn synchronous switchover functions, display voltage, frequency and phase differences of 2 circuits
Automatically close when the switch PF signal is active for energy-accumulated ATS
Over/under voltage and frequency, over current, loss of phase and functions for inverse phase sequence protection
Automatic/Manual modes switchover
On-site setting of all parameters can be set on-site
Password authentication to guarantee staff-only access
Genset can be manually-tested on-site to achieve start/stop operation
Real-time clock (RTC)
Event log function that can record 200 items circularly
Black box record function which allows the recording of 5 events circularly, 60 data of 50s before each event record and 10s after each event record
Scheduled daily, weekly or monthly functions for gensets, with or without load
Ability to control two generators to work in circular, master and balanced running mode.
Wide DC power supply range which allows the controller to bear a maximum of 625VAC voltage input
