Product Description Acrel Three Phase ARD3M Smart Motor Protection RelayIn the field of industrial control, electric motors are the core power of production lines, but frequent failures often lead to equipment damage, production stoppages and even safety accidents.Traditional motor protection methods:The circuit breaker provides short-circuit protection for the main circuit;Overload protection is provided by thermal relays;Disadvantages: simple functions, faults are difficult to troubleshoot and cannot be located.ARD3M intelligent motor protection controller is suitable for AC motors below 660V. It integrates protection, measurement, control and communication, provides fault records, assists in rapid fault location, extends motor life and improves production efficiency.Core functions: complete protection functions, support for multiple starting modes, integrated MCC function;Advantage functions: insulation monitoring, waveform recording, anti-electrical shaking, PROFINET communicationInstallation: It adopts split structure design, the main body and display unit are connected by network cable, easy to install, suitable for harsh industrial scenes such as high temperature and high humidity. Type: Smart Motor Protector Function:Phase loss,overload,locked rotor,blockage,three phase unbalance protection,etc. Measurement:Active kWh (positive and negative),quadrant reactive power energy. Electrical measurement: U,I, P,Q,S,PF,F,THDv,Harmonic on 2nd-31st,etc Communication:RS485, WIFI Protocol:Modbus-Rtu,MQTT Installation:Separated type or integrated How we can help you? The power module supports the power range of AC/DC100-415V. Support fundamental wave and full wave power parameter measurement (U, I, P, Q, S, PF, F, EP, EQ), voltage and current unevenness Balance, voltage, current positive sequence, negative sequence, zero sequence components, three-phase voltage phase angle, residual current, voltage, current 2-63 times Sub-harmonic measurement, sub-harmonic content rate and total harmonic distortion rate. Protection functions include overload inverse time limit, overload definite time limit, grounding, starting overtime, leakage, underload, phase failure, blockage Turn, block, short circuit, overflow, unbalance (current, voltage), over power, under power, over voltage, under voltage, phase sequence, temperature degree, tE time, external fault, limit of starting times, running time alarm, fault times alarm.10 programmable DI inputs, the default is built-in DC24V power supply, and external active wet contacts can also be selected 6-channel programmable DO output, which can meet the requirements of direct starting, star-delta starting, autotransformer starting, etc.The remote control "start/stop" of the motor from the master station can be realized through the communication bus. Optional anti-shock function: support immediate restart after shock and restart after loss of pressure. Standard 2-way MODBUS_RTU communication, there are PROFIBUS DPV1, Ethernet, PROFINET communication modules for Optional. Optional 2-way DC4-20mA analog output interface, connected with the DCS system, can monitor the field equipment. It has various event records such as fault record, start record, stop record, DI displacement record and restart record, which can be checked View a number of motor operation and maintenance information, and at the same time record the motor running record for 1-5 hours. The display interface supports Chinese/English display. Support U disk to export waveform record and event record data, you can use EXCEL to open and export event record file. WIFI function can be added when the color LCD display is selected, and the WIFI can be connected to the mobile phone or computer to view and set the motor protection.Its perfect protection function ensures the safe operation of the motor, with logic programmable function, can meet a variety of control methods.Different communication modules can be selected to meet the needs of field communication.
