AUTOMATIC POWER SWITCH ZGQ5-100/4P Feature: The use of silver contacts can greatly improve the conductivity and service life of the product Built-in regular standby opening signal output port, which can be connected to the signal control light, which is convenient do observation outside the cabinet Using high quality fireproof plastic, good insulation, high temperature resistance, anti-aging, safety and reliability When normal power supply is incorrect, backup power supply will work immediately to ensure continuity, reliability and safety of power supply Suitable do switch to emergency power when power is cut off, and do switch to main power source when power on Specification: Item Type: Automatic Dual Power Transfer Switch Model: ZGQ5-100/4P Material: plastic; Purpose: Switch to emergency power when power fails, and switch to main power source when power appears Working frequency: 50-60 Hz Rated Current: 100A Rated Voltage: AC110-230V Operating Voltage: AC220V Operating mode: automatic and manual ATS: level CB Conversion time: 0,05 (S) Number of Poles: 4P How to use: 1. Place the automatic dual power supply transfer switch on the debugging platform and connect the corresponding power line according to the correct phase order. The phase line and neutral line are connected in place, and an incorrect connection is not allowed. 3. When debugging a three-pole switch, a common and spare neutral wire must be connected do of the neutral terminal (NN and RN), respectively. 3. Set the automatic dual power switch to work in self-rotating and self-resetting mode. If the voltage of both power supplies is normal, the switch should be placed in the common power supply position, and the common power supply is closed. 4. Set common power supply NA, NB, NC, NN dla any phase loss, dual power supply should be automatically converted to backup power supply, if common power supply returns do standard, it should be converted back to common power supply 5. Adjust the voltage of any phase of the common do of the specified undervoltage voltage value, and the dual power supply should automatically switch to standby power supply. When the normal power supply returns do normal, the switch should return do normal power supply List of packages: 1 x Automatic Dual Power Switch 1 x User Manual
