EVESD3000 series intelligent dual power automatic transfer switch is the company adopts microcomputer control technology developed automatic transfer switch. The switch selection famous brand Merlin and ABB series circuit breaker load switch for actuators, and with a new control mechanism with a double interlock Mechatronics dual power switch models, especially for the important places not allowed off the power supply. The dual power switch is suitable for AC 50Hz, voltage 380V, current circuit 1A ~ 800A in order to meet the needs of the scene, it can be realized from the vote since the complex, mutual backup, manual and automatic conversion of three different ways of working. Through the power supply voltage deviation (undervoltage, overvoltage, loss of pressure) were detected to control the motor and other institutional transformation. EVESD3000 series intelligent dual power automatic transfer switch with intelligent operation, capable of working state clear display and alarm function with fault, is a new product combines the advantages of the domestic like product electrical performance and mechanical properties of the composition. When the dual power in the state can not fault trip automatic conversion circuit fault must be excluded before the ban does not exclude manual closing circuit failure. The dual power EVESD3000 with terminal type and basic type two. Swatch dual power switch is in working condition common failure analysis of several maintenance and troubleshooting to ensure the reliability of dual-supply operation, periodically (recommended every two months) to conduct a test to confirm the dual power switch is normal. To ensure continuity of supply load. Troubleshooting common when it comes to dual power does not work circumstances dual power switch, please see the list of the first fault. If you still can not be resolved, contact me or agents. Tripping the alarm normal or emergency power supply due to circuit breaker fault trip, warning lights "NB" or "RB" appropriate trip indicator light, but does not make the power conversion. Fault alarm is automatically released after discharge, but you must manually reset the circuit breaker. Fire is reset when the fire command center control unit dual input power switch suppliers, will enable two-way circuit breaker trips. Fire signal must be DC + 24V, disappeared after the fire command, you must press the reset button on the control unit to automatically re-entered the running state. User connection: 1. It is recommended when the switch is installed in the box to the mounting plate bolted to maintain. , 2. The switch with a common power supply, standby power indicator, indicating the circuit breaker is closed, the circuit breaker trip indication also provides an external output terminal (active) users of these indicator lights can be determined according to the required external concrete case, the user can refer to the product wiring diagram. 3. The ground wire must be reliable in order to ensure operator safety. Dual power switch manufacturers _ _ dual power switch only by Shanghai Thai Thai Industrial Co., Ltd.
