Product Profile of Universal Automatic Electronic Phase Switch
The Universal Automatic Electronic Phase Switch, under the model number PEF-301 is a microprocessor based single-phase unit of automatic throw-over circuit-breaker that performs monitoring of voltage presence & quality on phases. The switch is designed to supply an industrial/ appliance single-phase 220V/50Hz load from three-phase four-wire mains 3 x 380+N in order to maintain uninterrupted power supply of essential single-phase loads and protect them against unallowable voltage variations in the mains. Sabo Systems Pvt. Ltd., an ISO 9001: 2000 certified company manufactures Universal Automatic Electronic Phase Switch.
Sabo Systems Pvt. Ltd. is the supplier of LT Panels, Control and Relay Panels, Mimic panels, Control desk, Bus duct, etc. The Universal Automatic Electronic Phase Switch provides a simple and correct solution to enhance electric power supply reliability of single phase loads and to protect them from unallowable voltage variations in the mains. By monitoring three phase voltage existence / quality this switch will select automatically the optimum phase and enables the single-phase load to be activated from it.
