    Dual power supply

    Product Overview

    • NYKP2 series double power supply switch apparatus belongs to PC grade, it’s divided into NYKP2-2 and NYKP2-N3.
    • NYKP2-2 is two-section automatic transfer switch, after switch connects to shifting signal, it shall shift from one power source to the other from the middle breaking position without any stop, current size is 20A-500A.
    • NYKP2-N3 is three-section automatic transfer switch, when this switch connects to shifting signal, it can immediately (or through a preset delayed time) shift from one power supply to the other, or shift from one power supply to middle breaking position disconnecting with any other power supply. Current size is 20A-800A.

    Product Features

    • Reliable mechanical interlock: Unique eccentric selection mechanism ensures that there’s only one group of power supply, absolutely without two groups of power supply to connect to load simultaneously.
    • Good arc extinction performance: All types of abnormal electric arc shall be off reliably, electric arc continuity time is short, contact wearing is less.
    • Faster switching speed: Rapidly switch between two groups of power supply key: normal power supply and spare power supply, User also can set switching delay time of ATS equipped with controller.
    • Simple structure and small volume: It has reliable work, lower fault rate, convenient installation, use and maintenance. When repairing it, please slowly rotate handles for operation, so as to find out and remove the fault, NYKP2 series ATS belongs to PC grade, comparing to traditional CB grade products.
    • OFF position: NYKP2-N3 type three-section transfer switch can be shifted from power-on status to OFF for a short stay and not connecting to any other power source, bringing convenience to User, while NYKP2-2 type two-section cannot stay at this OFF position.
