summary

WDQ2 series dual power automatic transfer switch is controlled by a microprocessor, which is used for automatic transfer of dual power supply between power grid and power grid or between power grid and generator in the power grid system, enabling continuous power supply. In case of sudden failure or power failure of the common power supply, the equipment can still operate normally after being automatically switched to the standby power supply through the dual power supply switch.
This switch complies with the following clauses of the national standard GB/T 4048.11 Automatic Transfer Switching Apparatus: the operating mechanism shall have reliable electrical and mechanical interlocking to prevent the common power supply and standby power supply from being connected at the same time.

Structure and performance

structure
WDQ2-63 dual power automatic transfer switching device is composed of small circuit breaker, motor operating mechanism, control circuit, etc. independently developed by Zhejiang Weiju Technology, and all components are installed on the same base plate. The control power supply voltage of automatic transfer switching device is AC220V, and the mechanical life is 5000 times.

performance
WDQ2-3 dual power automatic controller (only automatic switching and automatic recovery) detects the phase voltage (automatic control power supply) of two power supplies (called common power supply and standby power supply respectively) at the same time. When the common power supply is abnormal, that is, phase A of the miniature circuit breaker loses voltage or phase, the automatic controller enables the device to switch to the standby power supply without delay: when the common power supply returns to normal, The automatic controller enables the device to return to the common power supply without delay, and two power supplies are not allowed to supply power at the same time.
Note: During manual operation, press the button to the manual position.

Feature

1. The structure is reasonable, the volume is small, the appearance is beautiful, equipped with a protective cover, and the power supply is more safe and reliable.
2. Complete protection functions, including short circuit, overload, phase loss, undervoltage protection, etc.
3. With EPS fire power interface, DC12-24 can be reliably and remotely divided.
4. Noise free operation, energy saving and consumption reducing installation, simple operation, reliable and stable performance.
