Application

ZMQ2 / F Series intelligent self-protection dual power switch (hereinafter referred to as switch) for AC 50Hz, rated working voltage 400V, rated current 16A ~ 2000A. Mutual conversion used in emergency power supply system of two common power supply (N) and standby power (R) between (can also be set to manual) and as a control, signaling, interlocking and other uses of the switching control circuit, the present products with some models designed communication port, which enables remote control, allowing users to achieve unattended substation. Suitable for residential areas, military facilities, hospitals, shopping malls, airports and other places.

Normal working condition

The installation altitude not exceeding 2000 meters.

The upper limit of the ambient temperature is not higher than +40°C, the lower limit of not less than -5°C, 24-hour average does not exceed + 35°C.

Atmospheric relative humidity in the ambient air temperature is + 40 °C not more than 50%, at lower temperatures can have a higher humidity, condensation products should take into account the surface of the humidity change.

No explosive medium, the medium does not enough to corrode and damage the insulation of gas and dust.

No significant shake and shock vibration.

Structure and Function

The intelligent switch two parts by the microcomputer controller and switching device component, a dedicated cable connection between the two.

Switching from the microcomputer controller, micro-motors, gear machine, micro switch, keyboard, LGD display, molded case circuit breakers and other components. With automatic and manual operation; machinery and electrical double interlock features to best meet supply and distribution needs.

There are three state switching positions for users to choose: the common power supply (N) together, double points, standby power (R) together, the switch has a small size, light weight, stable, easy to use features.
