FAQ

Under-voltage protection, also known as low-voltage protection or LVP, refers to the feature of circuits that prevents loads from automatically turning back on after a power outage when voltage returns. Instead, further input from the operator is required.

One popular application of undervoltage protection is safeguarding motors from damage caused by abnormal conditions, as well as preventing breaker-fed motors from re-accelerating once bus voltage is restored. However, this protection method also poses the risk of nuisance tripping when VTs fail.

Undervoltage can result in damage to equipment, as motor-driven appliances and certain electronic power supplies tend to consume higher currents at lower voltage levels, leading to overheating.

CHYT overvoltage protector is a circuit that is designed to prevent downstream circuitry from sustaining damage due to an overabundance of voltage.

Overvoltage can result from inadequate regulation of a power supply provided by a utility company, oversized transformers, uneven or fluctuating circuit loading, wiring mistakes, and failures in electrical insulation or isolation.
