Power services offers engine protection relay. It protects the engine from over speed, low oil pressure, low fuel, hi-radiator temperature. It has an electronic protection system that gets input from various sensors of speed, oil pressure, fuel-level, and radiator-temperature. These inputs are constantly monitored and compared with their respective limiting values. The moment, any one or more parameters crosses their limit, separate led indicator glows hooter actuates and a timer [30-60 sec] statrs to stop the engine. The relay is used in dg set monitoing, protection, and alarms. Specifications: auxiliary supply - 12 v/24 dc; sensors - hi-speed - gen frequency [single phase out put from alternator]; built-in; low oil pressure: pressure switch type [n/o]; low fuel - float switch type [n/o]; hi-radiator temperature - bi-metallic thermostat [n/o]; output - hooter - 1 change-over [potential free]; stop solenoid - 1 change-over [potential free]; and timer - for stop solenoid built-in.
