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.
