NDQ2 intelligent duplicate power supply automatic switching unit commonly called as A.T.S-automatic transfer switch ( hereinafter called as " Unit" is suitable for transferring between two circuit of power supply ( working power supply, standby power supply) with rated working voltage up to AC 400V, rated current up to 630A, frequency of 50Hz, .

NDQ2 series transfer switch take the molded case circuit breaker as the implementation component ; NDQ2 series transfer switch take the miniature circuit breaker as the implementation component., customer can make their choice basis the requirement.

Main functions and features

1, Double protections of reliable mechanical interlock between two circuit breakers and electrical interlock from MOTOROLA single-chip microcomputer to ensure switching reliably.

2, Fitted with over-voltage protection, under-voltage protection, phase fault automatic switching and intelligent alarm function;

3. Parameters may be set freely from external;

4, Smaller volume. Safe and reliable using convenience; lower energy consumption;

5 Fitted with fire-proof control function, when sending fire controlling signal to the intelligent controller, two circuit breakers are in OFF-status;

6 Construction of products is made up of quality cold rolled steel plate with beautiful and novel appearance, coating surface adopt advanced electrostatic powder coating technology with coat layer of good adhesion force and erosion resistance.
