West Germany dual power CDQ3-63 / 3P / 4P Product Description: automatic switching common power (N) and standby power (R) between (can also be set to manual switching), due to the way of a power outage or abnormal ( undervoltage, overvoltage, loss of pressure) and automatic conversion between the power supply, in order to ensure continuity of supply, reliability and security. Current capacity respectively 63,100,225,400,630A, electric operation of the motor (single-phase AC) motor is, reverse to drive points, closing for power conversion. Features: switch body consists of two parts and controller, using two or three * MCCB and internal accessories as the main switch; the controller is based on MSP430 microprocessor core, with low power consumption, stable and reliable; between them with two lengths of 1.6m with product-specific plug cable is connected. CDQ3 dual power automatic transfer switch owns three operating modes: automatic closing (1) controller; handmade (3) from the controller sub-closing; (2) the manual controller operated by sub-closing. (Note: The controller is integrated product installed directly on the floor switch body) West Germany dual power CDQ3-63 / 3P / 4P technical parameters dual power automatic transfer switch CDQ3-63 CDQ3-100 CDQ3-225 CDQ3- 400 CDQ3-630 Rated current (In) 10 ~ 63A 10 ~ 100A 100 ~ 225A 225 ~ 400A 400 ~ 630A poles Three-pole or four-pole circuit breaking capacity L *, M rated short-circuit making capacity 17KA 30KA 30KA rated short-circuit breaking capacity 10KA 15KA 15KA product operation cycles through current 5000 3000 2500 1000 1000 without current 500 times the rated insulation voltage (Ui) 690V rated working voltage (Ue) 380V (400V) switch body protection class: IP20, Controller: IP30 Note: L * indicates that only CDQ3-63, CDQ3-100, CDQ3-225 three poles have a breaking capacity L, the main structure and working principle of Chint Group ZQ1 dual power automatic transfer switch consists of two molded case circuit breakers and accessories, motor transmission mechanism, a mechanical interlocking mechanism, automatic controller, etc., all devices mounted on a metal base plate. The controller uses an internal MOTOROLA microcontroller and advanced, reliable electronic components intelligent automatic control circuit composed. Automatic controller works briefly as follows: automatic control of three-phase voltage power supply and standby power used for testing at the same time, 120% higher than the rating that ruled over-voltage, lower than the 60-85% (by specific parameters user-set) press undervoltage treatment. The internal circuitry of the test results of six voltage amplitude and phase of the judge, and the results after the adoption of the delay, driving the corresponding relay instructions issued by opening and closing instructions to the electric operation. Simultaneously with the detection results of 10 light-emitting diode display on the panel. Through four buttons on the front panel switches, two delay adjustment potentiometer, a voltage adjustment potentiometer can be set to four operating modes ("Auto - Manual", "common power", "standby power", "power failure (re-buckle) "), the conversion value of the delay time and undervoltage.
