Features: power converter Brand: West Germany Model: CDQ3 225 / 3P 4P Description automatic switching common power (N) and standby power (R) between (can also be set to manual switching), due to the way a power-off electrical or abnormal (undervoltage, overvoltage, loss of pressure) and automatic conversion between the power supply to ensure continuity of supply, reliability and security. Current capacities of 63,100,225,400,630A, electric operation of the motor (single-phase AC) motor is, reverse to drive points, closing for power conversion. Certification CCC certification standard IEC 60947-6-1 GB / T 14048.11 Features from the two major switch body and controller, using two three or four molded case circuit breaker and internal accessories as the main switch; the controller based MSP430 microprocessor core, low power consumption, stable and reliable; connected between them with two product-specific cable length of 1.6m with a plug. CDQ3 dual power automatic transfer switch owns three operating modes: automatic closing (1) of the controller; manual (3) from the controller sub-closing; (2) the manual controller operated by a sub-switch. (Note: the controller integrated product is installed directly on the floor switch body.)
