Features 【Fast Switching】 The switching response time of the ATS electronic switch is ≤ 0.05(s). When an anomaly occurs in the normal power supply, the backup power will respond immediately and switch in milliseconds, ensuring continuity, reliability and safety of the power supply. Built-in normally standby opening signal output port, which can be connected to the signal indicator. 【Fireproof Material】Photovoltaic backup power switch made of high quality fireproof plastic, with good insulation, high temperature resistance, aging resistance, safe and reliable. The use of silver contacts can significantly improve the conductivity and service life of the product. 【Observation】 The emergency switch has a connection for a timed standby signal, to which an external signal indicator can be connected to allow easy monitoring outside the control cabinet. It supports 35mm rail mounting with 57mm switch height. 【Satisfaction Guarantee】We stand behind our best service, high quality products.

Specifications: Item Type: Dual Power Automatic Transfer Switch Model No.: ZGQ5-100/2P Material: plastic. Purpose: Switch to backup power in case of power outage and switch to main power when power supply arrives. Working frequency: 50-60Hz Rated current: 100A. Rated voltage: AC110-230V. Operating voltage: AC220V. Operating mode: automatic and manual ATS: CB level Conversion time: ≤0.05(S) Number of poles: 2P How to use: 1. Place the dual power automatic switch on the debugging platform and connect the corresponding power line in the correct phase order. The phase line and neutral line are connected in position and cannot be connected incorrectly. 2. When debugging the three-pole switch, the common neutral wire and the spare neutral wire should be connected to the terminal of the neutral wire (NN and RN) respectively. 3. Set the dual power automatic transfer switch to work in auto-rotate and auto-reset mode. When the voltage of the two power supplies is normal, the switch should be set to the common power position, and the common power supply should be closed. 4. Set the common NA, NB, NC, NN power supply for each phase failure. Dual power supply should be automatically converted to backup power supply. When the common feeding returns to normal, it must be converted back into a common feed.
