Every household, every object and every machine needs a watch relay. There may be several reasons, such as overvoltage, undervoltage, phase failure, asymmetry, frequency, or power factor. It does not matter if it is a voltage or current with a single-phase or three-phase distribution, you will definitely choose from our offer.
Voltage Monitor Relays monitor either AC single phase (50-60Hz) or DC voltages to protect equipment for undervoltage and overvoltage fault conditions. The relays can be used as either overvoltage or undervoltage relays, depending on the output contact used.
Used to monitor the value of alternating current in, e.g.: motors, heating cables, illumination and other devices
They monitor the level of conductive liquids in wells, tanks, reservoirs, etc. They can monitor from one to six levels of water with optional fill / drain functions. These are either separately marketable products, or directly involved in the setup with a contactor or motor starter.
The devices can monitor the temperature in the home or also in industrial applications. They are used for house temperature control, winter gutter and pavement defrosting, temperature monitoring in a cabinet, as motor protection against overheating, water heating, temperature control of boiler , water storage, solar systems, moisture monitoring and other industrial applications.
The relay serves to monitor frequency of AC voltage, e.g. in photovoltaic power stations, generators.
