I. Product Overview
YDQ3-63 mini dual power automatic transfer switching equipment is dedicated to the electrical power conversion device terminal double for AC 50Hz or 60Hz, rated working voltage 400V, rated current 63A and below the double-loop power supply system. According to the need for selectivity between two power conversion. Products with short circuit, overload, under voltage, voltage protection function, but also has prepared the fire, two points and closing signal output function. Especially suitable for a main one power conversion system, as fire, hospitals, shopping malls, military engineering, high-rise buildings do not allow a power outage of the main power supply place of use. It is in line with GB/T14048.11-2002 "Automatic Transfer Switching Equipment", "high-rise buildings for fire protection", & nbsp; "building design", & nbsp; "Emergency Lighting Design Guide", & nbsp; "civil electrical design specifications" and other norms or standards.


Second, the normal working conditions
● installation site altitude does not exceed 2000m.
● relative humidity of the atmosphere in the ambient air temperature is + 40 ℃ not more than 50%, at lower temperatures can have a higher temperature;
● wettest month of the monthly average minimum temperature of + 25 ℃, the mean maximum relative humidity of 90%, and taking into account changes in humidity condensation surface of the product, should take special measures.
● pollution degree Ⅲ pole.


Third, the model and the meaning of

Fourth, the basic structure
Mini dual power automatic switch
is mainly executed by the power converter circuit breaker (including the implementation of the common power supply and backup power circuit breaker DZ47 circuit breaker DZ47 execute each one) part of the automatic control box, electric operating mechanism and other components. Breaker DZ47 circuit protection and over-current protection function, as both off and protect the main circuits.

five assembly wiring
When wiring, the common power supply should be connected to common power execute N breaker DZ47, standby power R should then execute backup power circuit breaker DZ47, DZ47 circuit breaker when the four-pole, three-phase 1,3,5 carried off, 2,4 6 three-phase outlet end, 7 zero line into the line side, 8 zero line outlet end, if the choice of circuit breaker for the three-pole circuit breaker, it must be the common power supply (N) of the zero line NN and standby power (R ) NR zero line also received a zero on three poles dedicated wiring terminals.
Note: Line terminal and zero line terminal operating power dual power switch automatically from the breaker DZ47 controller, and if the choice of the three-pole circuit breaker must be connected to two electrical zero line and NN and NR, the three very special terminal in the middle of two circuit breakers. Automatic power switch installation, wiring process, do not cut into the line connected to the original end of the machine to get rid of the control line, touch off or shorted.

Six, using the operation
Regardless of whether the common power supply and standby power supply voltage, can be manually operated. In manual operation, you should manually - Auto button in the manual position, when the push handle is rotated clockwise to the terminal, perform backup power circuit breaker, the common power supply execution breaker closing, when the push handle is rotated counterclockwise to the terminal standby power circuit breaker closing execute, execute circuit breaker plant with power.
Panel, power indicator (green) indicates the power supply automatic control box, if the lamp is not lit, indicating automatic control box work power failure, you can not operate, to be repaired properly, the manual - automatic automatic position state, if common power supply is normal, the switch will automatically put into the implementation of the common power supply circuit breaker closing state, the panel N Power indicator (red) light; as check the common power supply is not normal, the nipple will automatically switch the circuit-breaker, spare circuit breaker the state is closing position, R panel power indicator (red) light


Seven features
● anti-interference ability, high precision;
● fire power DC24V, fire double points;
● Small size, breaking high, arcing short, compact structure, beautiful appearance;
● Simple noiseless operation, energy saving, easy installation and operation, stable, high performance;
● switch has automatic recovery function;
● according to the actual needs of the design circuit connected common power supply and standby power supply (or generator) into the round, the zero line. To ensure security, the need to convert the ground floor and reliable switch, outlet end of two circuit breakers in parallel, but the phase sequence must be consistent;
● When three-pole circuit breaker, the NN, NR (zero line) are respectively connected to the switch (N) 2, (N) 4 (neutral) terminal, or can not work properly;
● switch operating handle, the handle of the operation as an emergency use. (But you must press the control mode "manual" state), you can use the operating handle.
