Solatron™ Plus Series Instruction Manual • 5

3.0 Introduction

The SolaHD Solatron™ Plus Series is designed to provide a tightly regulated,

isolated voltage source to sensitive loads. It increases reliability by improving

efciencyandextendingtheusefullifeofprotectedloads.

Input voltages from -25% to +10% are corrected to ±3% of nominal voltage with

a response time of <1.5 cycle (typical). Output voltage regulation is accomplished

byusingsiliconrectierswitchesandamulti-taptransformerarrangement.Tap

transitions are made in a secondary control circuit and at less than full load current,

eliminating voltage notching during each transition.

3.1 Features

RuggedConstruction: All magnetic and electronic components have been

designedtoinsurethattheSolatron™Pluswillprovidethespeciedvoltage

regulation to the most demanding electrical loads.

Protection: All units protect against system transients and overvoltages using a

Surge Protection Device (minimum 80 kA surge current rating).

NoHarmonicInteractions: The unit is unaffected by harmonic voltages and

currents, and produces no distortion during normal operation.

HighOverloadCapacity: Motor starting and momentary overloads will not trip

the unit, and output short circuits will not damage the unit.

DiagnosticDisplay: Panel mounted indicating lights for bypass and high

temperature conditions.

Fail-SafeBypass: SCR, power supply, and other component failures will result

in an automatic electronic bypass with no interruption to the load – nominal input/

output voltage with isolation and surge suppression active.
