Low voltage motor protection controller/PDM-810MRC (H)

Standard Configuration

• It has multiple protection functions such as short circuit, locked rotor, overload, grounding, phase loss/imbalance, TE curve, starting timeout, under/over voltage, under power, etc

• Measure three-phase current, three-phase voltage, zero sequence current, power, electrical energy, and current imbalance, provide comprehensive protection for the motor, and have the function of recording protection events;

• Protection method: Relay protection output method, which is connected to the secondary operation circuit through the normally closed point of the relay to achieve protection function;

• Wide range AC/DC universal power supply: AC/DC85V~265V;

• 1RS-485 communication interface (optical isolation), Modbus RTU communication protocol;

• 8Passive switch remote signal input, capable of collecting external state variables;

• 4Circuit relay protection control output, used to protect tripping and fault alarm output functions, etc;

• Display mode: LCD Chinese LCD display, real-time reading of three-phase current measurement values and protection

• The recording of protective events and protection parameters can be set by the display panel and communication software;

• Adopting rear plug-in terminals for easy installation and wiring by users;

Optional configuration

• 1Programmable DC 4mA~20mA analog output; (A)

• 1Type-C communication interface, Modbus RTU communication protocol; (TYP1)

• External zero sequence/leakage current transformer input, measure zero sequence/leakage current; (Y1A/Y50)

• Restart after losing pressure; (Z)

• There are two ways to input current, and users can flexibly choose according to their needs:

1.Specialized small CT input (MT optional): 0.4A-3A (MT5), 2A-15A (MT25)

15A-60A(MT100)、30A-90A(MT150)、60A-150A(MT250)；

2.150AThe above uses standard CT and MT5 in combination;
