Phase switcher DigiTOP PS-40A

The PS-40A phase switch is designed to supply industrial and domestic single-phase 220/230V 50Hz consumers from one of the phases of a three-phase network in order to ensure the supply of the most critical single-phase devices from the phase of the highest quality and protect them against overvoltages or undervoltages. The device is controlled by a microcontroller that analyzes the voltage in the three-phase network and displays the actual values ​​on digital indicators for each phase. The output is switched to the load by electromagnetic relays. The device is powered from monitored phases. Programmable settings: – Permissible voltage switching/disconnecting limits – Priority phase – Load transfer delay time – Switching delay time for the lower limit – Delay time to return to the priority phase Specifications: Voltage on each phase, V: 50-400 Load rated current: 40A Maximum load current: 50 A Off/switching time for upper limit, s: not more than 0.02 Off/switching time for lower limit (<120V), s: not more than 0.02 Upper limit of tripping/switching: 210-270 (250*) V Lower cut/switch limit: 120-200 (170*) V Priority Phase: L1,L2,L3 (OFF*) Load on delay time: 0-600s (0*) Switch delay time at lower limit: 1-10 sec (1*) Switching delay time to priority phase: 5-120 sec (5*) Voltmeter accuracy, %: no more than 1 Device protection degree: IP-20 Output control from "sticking" the contact: yes Size: 7 modules DIN rail mounting Warranty 5 years All set values are stored in non-volatile memory.
