1. Introduction
1.1 Overview
PWM SERIES
microprocessor controlled Single Phase Static Digital Voltage
Stabilisers automatically correct brownouts (by boosting low voltage)
and over-voltages (by reducing high voltage). They are, designed to
ensure the delivery of a stable and quality output voltage.
Being designed for many years of reliable service, VSi’s
PWM
models
provide protection from incoming line voltage sags, spikes and surges /
swells. As Static Digital solutions they are virtually maintenance free and
offer an exceptional fast speed of correction, making them ideal for the
most sensitive of electrical and electronic loads.
1.2 Basic Principle of Operation
PWM SERIES
AC Voltage Stabilisers are designed around a traditional well
proven ‘Buck / Boost’ design topology, utilising the latest in IGBT Power
Devices and digital PWM (Pulse Width Modulated) controls.
Please Note
:
PWM
Voltage Stabilisers are
NOT FOR USE
with life
sustaining equipment, or any device where the power requirements
exceed the “Maximum Output Rating” listed in the General Specification
tables. These Stabilisers are not designed to support / protect voltage
“back feed” applications, where energy is required to be also fed back
into the utility supply.
