HPMV-DN series medium voltage solid-state soft starter device is designed to the new high-tech electrical equipment based on the third generation digital microprocessor-controlled technology and modern electronic power control technology. It is used to offer the optimal drop down-current limit soft start method for motors. To adapt to different load conditions and to reach better starting effect, a variety of control modes are applied to HPMV-DN soft starter, and thus the motor can smoothly start in accelerating state at the minimum current, therefore effectively reduce the voltage drop of grid when starting, in the meantime, lower starting current and mechanical shock. When soft stop is required, the gently tapered controllable voltage can be provided to the motor for the smooth stop of the motor drive system.

Manage the data and communication by digital CPU, strong anti-interference ability by signal access and isolation. More stable and reliable. HPMV-DN is a kind of high-performance digital soft starter, support smooth ramp up and ramp down of motors and reduce current impact and mechanical impact of motor and power net. Advanced optical fiber and optical fiber trigger technology ensure a full isolation of high voltage system and low voltage system. In the meantime support a perfect trigger, testing and isolation of high voltage SCR and control circuit.

Features:

- Advanced high frequency isolation and transfer technology support perfect working power for the components of high voltage system.

-Static and dynamic average voltage technology support reliable running of main components of serial connected high voltage.

-Advanced wireless voltage testing technology. Electric EVT technology, stable signal communication, no interference or-remove.

- Six starting curves, to suit different kinds of motors and applications. Automatically adjust the rotate speed of motors, smooth and stable accelerate curve, reduce electrical and mechanical impact.

-Six stopping curves, to suit for different kinds of loading, with the function of terminal torque adjustment. High effective to against pump's water-hammer while sopping period.

-Smooth step-less acceleration and deceleration.

-Pulse start, increase starting torque.

-Rich protection functions which includes over voltage, under voltage, over loading, under current, phase loss, phase unbalance, phase sequence wrong, grounding, over temperature of SCR, over starting time, starting cycle limit, SCR faulty protections and so on.

-Low voltage testing method. To test the full functions and quality of HPMV-DN soft starter by a low voltage motor. Support a complete performance report and parameter record.

-KYN24A-12 housing, raw material is made by imported aluminized zincograph. With the advantage of anti-corrosion, oxidation resistance, nice visual, high protection level. And easily to connect with other standard HYN28A-12 middle cabinets.

-For generator supporting conditions, special control program can guarantee a successful starting on unstable voltage, current, frequency, as well 1.35 times of motors capacity.

-Dual parameter input: for dual speed motors and power net and generator supporting electricity conditions, and for one drive two motors conditions, soft starter can input tow instructions of starting and stopping through required parameter by PLC.

-Friendly control menu and record index. Touch screen (optional).

-The RS485 communication with Modbus or Profibus protocol enables full control isolation testing function.(optional)
