Scope STQ1-63 dual power automatic transfer switching equipment (hereinafter referred to as switch) for AC 50Hz or 60Hz, rated working voltage 400V, rated operating current 63AQ 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 the fire, two points and closing signal output function. Especially for the need for office buildings, shopping malls, banks, railway stations, hospitals and high-rise buildings to install fire lighting circuits required. Product complies with GB / T14048.11 standards. 1. normal operating conditions the ambient air temperature limit does not exceed + 40 ℃, the lower limit of not less than -5 ℃, 24h average does not exceed + 35 ℃. 2. The installation site altitude less than 2000m. 3. atmospheric relative humidity in the ambient air humidity + 40 ℃ when not more than 50%, at lower temperatures, high humidity may have; monthly average minimum temperature of the wettest month of + 25 ℃, the average of the maximum a relative humidity of 90%, and taking into account changes in humidity Cream product surface, should take special measures; 4. Pollution level Ⅲ. 5. Run the place without a strong vibration and shock, no corrosion and damage the insulation of harmful gases, no serious dust, non-conductive particles and explosive hazardous substances, no strong electromagnetic interference. Product Features 1. Reasonable structure, smallest, beautiful appearance, with a protective cover, more secure and reliable power supply. 2. Protection function, with short circuit, overload, phase, undervoltage protection. 3. Fire and EPS power connector, DC12-24V can be a reliable long-distance double points. 4. No noise operation, energy saving easy to install, simple to operate, reliable and stable performance. STQ2 automatic power switch is mainly composed of the basic structure of the implementation of the power conversion circuit breaker composition, there are three state switching positions for users to choose: the common power supply (N) together, double points, standby power (R) together, the switch has a small Siemens dual power switch, light weight, stable, easy to use and so on. STQ2 automatic power switch using the operation regardless of whether the common power supply and backup power supply voltage, can use the manual mode of operation. Manual operation ABB dual power switch, you should manually Auto button in manual operation position, when pushing the handle clockwise to the terminal, perform backup power circuit breaker opening Qr, common power to perform breaker QN closing; when push When the handle counterclockwise to the terminal, perform backup power circuit breaker QR closing, the common power supply execution breaker QN opening. Warnings 1. not with plug controller plugs million high dual power switch, otherwise it will cause an electric shock or product damage. 2. The non-professionals to prohibit the operation or modification, or they will cause an electric shock or product damage. 3. This product users without changes, this will cause damage to the product. 4. Load capacity can not exceed the rated capacity of the switch, otherwise it will lead to switch tripped or burned. 5. Do not be neutral (n) mistakenly access phase dual power switch, two input circuit breaker must be consistent, the choice of a three-pole circuit breaker. 6. can not be directly installed in outdoor work. 7. not be installed directly in explosive, moisture, direct sunlight, high temperature, vibration, shock and other places. 8. can not be directly installed in a conductive dust. 9. shall meet the requirements of the sample, otherwise it will shorten life.
