Medium Voltage Drive MV510

Adopting voltage cascade technology for power cells, MV510 provides lower dv/dt insulation stress for motor winding and it’s also not necessary to add any external reactor device.

Built in large LCD touch operation panel with Chinese and English interface, it is easy to operate and real-time monitoring of running status via optional communication protocol RS485 Modbus, Profibus, DeviceNet and Ethernet. MV510 can be designed to meet different customized specification during 2.3kv-13.8kv input or output voltage.

Product Features

High Quality Power Input: By phase shifting of the secondary winding and multi-pulse diode rectifier, isolated powers can be acquired and supplied for power cells. (36pulses  for 6.6Kv, 54 pulses for 11kV) By using the technique of multi- pulse rectifier, the harmonic current could be eliminated greatly.

The Features of Nearly Perfect Power Output: The technique of multi level & cascade applied in MV510 general medium voltage drive greatly eliminates the output harmonic content. The output waveform is almost a perfect sine waveform(see Figure 2 and Figure 3). Compared with other high voltage and high power MVDs, it has the following advantages: No need of extra output filtering device; Directly driving the general high voltage synchronous or asynchronous motor, and the temperature of the motor will not be increased; No need of motor derating operation; No dv/dt damage to insulation of motor and cable; No torque ripple induced by harmonics, and the service life of motors and mechanism devices can be extended; No cable length limited when voltage drop is in the allowable range; The simple configuration for driving standard high voltage motors directly realizes highly efficient operation with minimal loss due to no input voltage transformers.

HMI with Powerful Function : Systematic Control on Touch Panel; Monitor & Control for Operational Status; Monitor & Control for Temperature & Status of Power Cell Unit; Operation Function Test by Using Low Voltage; Recordable 100 trips; Password setting; Remote Control; Emergency Stop.

Flexible and easy installation: To meet customers" request, MV510 can provide any possible entries and exits on top, bottom or both for installation.
