Single-phase monitoring relays are equipment for automatic control of effective voltage, as well as equipment such as household appliances and other equipment in home and office protection.
It is designed to protect against voltage variations that are not allowed in single-phase load power supplies. They have a wide range of adjustments, including turn-on time delays to protect refrigeration, compressors and air conditioning equipment.
