DTQ1 Dual Power Transfer Switch

Product application:

DTQ1 Micro-Breaking Dual Power Transfer Switch (hereinafter referred to as transfer switch) is suitable for AC 50/60Hz dual power supoly system with rated operating voltage of 400V amd rated operating current form 16~63A. Optional transfer of dual power can be made according to requirement,. The product owns short circuit, overload, under voltage and loss-of-voltage protection function, as well as fire protection, double-break and output ON signal function. It's especially suitable for lighting circuit of office building, mall, bank, bus station and high-rise building requiring fire product complies with GB/T14048.11 standard.

Working Conditions:

1、The ambient temperature shall not be higher than+40℃, or lower than-5℃, and the daily average shall not exceed+35℃ . 
2、The altitude of installation site shall not exceed 2000m. 
3、Relative humidity shall not exceed 50% at the ambient temperature of +40℃，a higher humidity is allowable at a lower temperature, the average maxinmum relative is 90% in the wettest month at a monthly average minimum teperature of +25℃, and special measures shall be taken for the condensation on surface of product due to temperature change 
4、Pollution calss: class III. 
5、In place of no intense vibration and impact, no harmful gas corrosive and disruptive to the insulation, no sever dust, no conducting microparticle and explosive substance, no high electromagnetic interference. 

Product Featurres：

1、Reasonable structure, small volume, nice appearance, with provided with protective shield, safer and more reliable power supply. 
2、Complete protective fun ctions, including short circuit, overload, open phase and loss-of-voltage protection. 
3、Reliable remote double-break with EPS fire protectin power supply interface DC12-24V. 
4、Noiseless, energy saving, simple installation, easy operation, raliable and stable performance.

Product Performance：

1、The transfer switch is composed of two DTQS69 Micro-Breaking and motor and mechanical rotating divice, and make detection to daul power through controller, when abnormality controller, when abnormality occurs to the circuit, the controller will make a logic judgment for the detection result and drive the operating mechanism to switch on or off according to according to command of controller, ensuring safe and reliable and stable performance.
2、Rated short circuit breaking capacity: 3kA. 
3、Rated short circuit making capacity: 3kA.
