Voltage & Phase Monitoring Controls

Sophisticated monitor functions control supply voltage and protect systems against over-current, under-current and phase failure. Available for AC and DC circuits, single and multiple phase applications, with fixed or adjustable time delays. Easy-read LED indicators show operation, conditions and faults. Peltec monitors have UL and CE approvals and are RoHS compliant. DIN Rail case design ensures easy installation.
