Delta MH300 Compact Variable Frequency Drives

WOOLARS supplies Delta MH300 variable frequency drives for industrial purchasing and replacement inquiries. Find the complete ordering code in the reference below, then send your required quantity and destination for a quotation. For a new machine, include the motor and control requirements so the requested configuration is clear.

Buying an MH300 for tension or feedback control

The MH300 is a high-performance compact vector control drive. Delta identifies winding and unwinding, machine tools, textiles and woodworking among its applications. Its built-in tension-control functions include roll-diameter calculation and tension taper, while optional PG cards support feedback-based motor control. These capabilities make the control arrangement an important part of an MH300 inquiry, alongside voltage and motor power.

For a winding or unwinding machine

Describe whether the drive controls speed or torque, how tension is measured, and whether encoder feedback is used. Include the existing option-card codes when replacing an installed unit.

For a machine network

Identify the required protocol and any installed communication card. MH300 provides built-in Modbus and CANopen interfaces; other networks require the appropriate options rather than an assumption that every protocol is included.

For an existing drive

Send the entire nameplate code and any fitted accessories. Motor kW alone is insufficient to establish a replacement match.

MH300 model reference and catalog ratings

The following standard models are grouped by input supply. Capacity and current are catalog references; final selection also depends on the motor current, duty and installation conditions. This is the model range handled on this page, not the complete MH300 catalog.

The verified standard models below are IP20 versions without a built-in EMC filter. Check enclosure and filter requirements for the machine rather than substituting another suffix on the basis of a similar model name.

230 V class input

460 V class, three-phase input: 0.4–7.5 kW catalog range

460 V class, three-phase input: 11–45 kW catalog range

Additional ordering-code inquiries

For inquiries specifying VFD7A5MH21ANSHA or VFD25AMH43ANSHA, send the exact code and nameplate photo. Their detailed specifications are subject to confirmation before quotation; standard-model ratings in the tables above should not be applied to these codes.

Send your MH300 model for a quotation

Request an MH300 quotation from WOOLARS using Get A Quote or the inquiry options on this page. Include the complete model, quantity and destination. Product condition, availability and lead time will be confirmed for the specific inquiry.

For technical reference, see the Delta MH300 English catalog, the Chinese catalog with extended standard-model ordering tables, and Delta’s MH300 product information. Check the applicable user manual before installation or commissioning.
