GRT-RM Intelligent Low Voltage Composite Switch
Product
1.GRT-RM-450 composite switch is a kind of switch that can be put into operation by signaling through external contact, and is intelligently controlled by microcontroller to put into operation by magnetic retention relay.
The magnetic retention relay is intelligently controlled by the microcontroller to put in the voltage over zero and remove the current over zero,
The switch is a three-phase common complementary casting and switching device which is used for voltage over zero input and current over zero removal by microcontroller intelligent control magnetic retention relay.
2. The switching device inherits the advantages of SCR and AC contactor, and has the advantages of low inrush current, low energy consumption, and high efficiency.
It has the features of small inrush current, low energy consumption, small size, phase failure protection, voltage abnormality protection, operation status indication and so on.
Low inrush current, low energy consumption, small size, phase failure protection, voltage abnormality protection, operation status indication, etc.
3. The trigger signal is adapted to dynamic power factor controller, programmable controller
or other controllers.
Advantageous features
1. Applicable to grid voltage 380/400VAC dynamic PFC system
2. Adopting microprocessor intelligent technology, voltage over zero input, current over zero cut-off, fast response speed.
Fast response speed
3. Adopting magnetic retention relay, with small on-resistance and low energy consumption.
4. Trigger signal is optically isolated from the switch, high security.
