Delta Products Corporation, the world’s largest power supply manufacturer, has introduced the new MH300 / MS300 Series high performance and standard compact AC motor drives.

Designed for micro variable frequency drive (VFD) applications up to 30 HP, the MH300 delivers high speed up to 2000 Hz operation for either induction motors or permanent magnet motors. It also features built-in PLC and Safe-Torque-Off features as standard, energy saving modes, and network expansion including EtherNet/IP, Profibus, DeviceNet and Modbus TCP.

The MH300 Series also allows for additional I/O and encoder feedback modules, and the option for connecting to EtherCAT for the highest performance and synchronized network control.

Compact

Both drives are physically compact – up to 40% smaller than similar models with the same horsepower – and deliver high speed start-up plus fast acceleration and deceleration. Both are also equipped with brake choppers.

Reliable

Built to be highly reliable, their 100% coated printed circuits boards allow these new drives to withstand dusty and harsh environments for longer periods.

Capable

Beyond impressive speed, power and compact size, these drives were specifically designed to be exceptionally user-friendly. Plus, all of their parameters match those of Delta’s VFD-C2000 general-purpose drive, making the entire product line easily scalable from fractional horsepower to over 800 horsepower. And among the new drive’s timesaving features is a keypad jog-wheel (MH300 Series), plus spring terminal I/O, and application-based parameter grouping.

The MH300 offers five control methods – volts per frequency; sensor-less vector control; volts per frequency plus encoder pulse generator; field oriented control plus encoder pulse generator; and torque control plus encoder pulse generator. These last three give the MH300 more precise motor speed control.

The MS300 offers two methods – volts per frequency and sensor-less vector control.

The MH300 range is 0-2000 Hz, while the MS300 range is 0-1500 Hz.

For communications, the MS300 has built-in Modbus. The communication option cards are CANopen, DeviceNet, EtherNet/IP, Modbus TCP, and Profibus DP. And the MH300 has built-in Modbus and CANopen with the same communication option cards as MS300, plus EtherCAT. The MS300 has one option card slot while the MH300 has two option card slots, for more versatility.

The MH300 can control up to eight motors simultaneously, while the MS300 can control up to four.

For a compact, reliable and capable variable frequency drive, the MH300 / MS300 Series from Delta Products Corporation is the one to choose.
