Yueqing lightning surge electric main dual power switch, dual power switch, dual power supply manufacturer, dual power wholesale price WATSNA-250 / 4P Sales Hotline: 18767770048 Mobile: 15157772419 Online QQ: 3229842726 Contact: Mr. Zhu supply WATSNA- 250 / 4P dual power switch a, CB-level product structure and characteristics ★ CB-class series intelligent dual power automatic transfer switch is composed of two three-pole or four-pole molded case circuit breakers and accessories (auxiliary, alarm contacts) , mechanical interlocking drive mechanism, intelligent controller and other components. Integral split into two structures. Integral with the controller and actuator mounted on a base; split is the controller installed in the cabinet panel, actuator mounted in the cabinet installed by the user, the controller and the actuator with about 2m long at the base of cable connection. Its characteristics are: a reliable mechanical interlock and electrical interlock protection between two circuit breakers ★ completely eliminate the possibility of simultaneous closure of two circuit breakers. ★ intelligent controller uses a microcontroller to control the core, the hardware is simple, powerful, easy expansion, high reliability; ★ short-circuit, overload protection, overvoltage, undervoltage, phase automatic conversion and intelligent alarm functions; ★ Automatic conversion parameters can be set freely in the outside; ★ having an operation intelligent motor protection function; ★ this unit with fire control circuit, when the fire control center to a control signal into the intelligent controller, two circuit breakers into the sub-gate status; ★ leaving many computer networking interfaces, in order to prepare to achieve remote control, remote adjustment, remote, telemetry and other four remote functions. Two, WATSN series of product structure and characteristics WATSN series intelligent dual power automatic transfer switch is composed of two three-pole or four-pole miniature circuit breakers and accessories (auxiliary, alarm contacts), mechanical interlocking drive mechanism, controller, etc. components. Its characteristics are: ★ with small, simple structure; easy operation, long service life, 3P, 4P are available; ★ switching driven by a single motor drive, smooth, no noise, small impact force; ★ having mechanical interlock and electrical interlock, conversion, reliable, manual, automatic conversion can be; ★ commonly used spare breaker rating may be different; ★ ATS built with terminals for customer connection can reflect breaker (open or closed) state; there are all the ATS panel kind of indication. Third, it works when the normal power supply is normal, when the function keys placed in the automatic transmission, the standby breaker, breaker used together to protect the common power supply connected to the load. A common power supply when one phase or three-phase full voltage is interrupted, ATS will transfer the load from the normal source to a standby power supply (when the standby power supply is normal voltage), and restore the normal power supply to normal, turn to the normal standby power conversion power supply. The use of operating and maintenance regardless of whether the common power supply and standby power supply voltage, can be manually operated. In manual operation, you should manually - Auto button in the manual position, when pushing the handle clockwise to the end, the standby power execute circuit breakers Qr opening, closing common power execute circuit breakers Qn; when pushing the handle counterclockwise to the terminal, the standby power switch on the implementation of circuit breakers Qr, common power execute circuit breakers Qn opening; panel power indicator indicates the power supply automatic control box, if the lamp is not lit, the power supply automatic control box is defective and can not be the operation switch. After the restoration of normal, the manual - Auto button in the automatic position, if the common power supply is normal, the switch will be transferred to the common power supply, the panel used the power indicator light; if the common power supply is not normal, the switch will turn the backup power supply, standby power indicator light panel. 1A switch has two fuses and a terminal block, fuse as short-circuit protection with automatic controller. Terminals was the lights connected to the control box panel provide active power source voltage is AC 220V, current of 150mA, which refer to specific operating instructions supplied wiring diagram for connection. Fifth, failure analysis and elimination occurs when the power supply is in the automatic control state change, electrically operated mechanism does not operate, the miniature circuit breaker is not closing or opening, you should check: (1) the grid is a blackout; ( 2) whether the wiring off; (3) the product itself, the fuse is blown. If any of the front-end circuit breaker has power, but they are correct wiring, fuses are intact, but still not closing or opening, you should please professional maintenance or contact the manufacturer to resolve. Supply WATSNA-63/3 dual power switch to meet the site requirements, automatic transfer switches and automatic recovery can be achieved, since the vote of no self-recovery, backup each of three different ways of working. Mainly applied in the business layer buildings, telecommunications, mining, ship, military, machinery, fire protection, elevators, industrial pipeline and other required uninterruptible power supply situation, as important to ensure a continuous supply of electrical devices.
