Delta Inverters

Delta Inverters


Modular Design Modular structure and extension with optional cards

Standard MODBUS Protocol – Standard MOD BUS Protocol via R8-48S

Built-In EMI Filter (230V 1-phase and 460V 3-phase) – To reduce electromagnetic interference efficiently.

Compact Design – Space saving and euy DIN rail mounting with optional DIN rail adapter.

Optional Fieldbus Modules – Provide connection to a variety of networks, including Profibus, DeviceNet, LonWorks and CAN open.

Flexible Extension – Via optional cards, such a1 I/O card, Relay card, PG (Encoder) card and USB card, to meet your application requirement.

RFI-Swltch for IT Mains – Removable “Y” capacitor to use with IT mains supplies.

Easy DC BUS Sharing – Multiple VFD-E can be connected in parallel to share the regenerative braking energy. In this way, over-voltage is prevented and the DC-bus voltage stabilised.

Complete Protection Function – High precision current detection, full overload protection (oL, oLl and oL2), over-voltage/over-current stall prevention, short-circuit protection, reset after fault, speed search function and motor overheat protection by PTC.

Removable Keypad – Tho standard keypad acts as a status monitor. More functions, including parameter modification, RUN/STOP, speed change, and status display, via optional keypad.

Power Range

1 – phase 115V series: 0.2 – 0.75kW (0.25-1hp)

1 – phase 230V series: 0.2 – 2.2kW (0.25-3hp)

3 – phase 230V series: 0.2-7.5kW (0.25-20hp)

3 – phase 460V series: 0.4 – 22kW (0.50-30hp)

Built-In PLC Function – Easy to write PLC proaram without additional PLC

Side-by-side installation (40°c) – High-efficiency cooling and flexible space

Easy Maintenance – Removable cooling fan for easy maintenance


Application Cases

Vacuum compressor

It reduces the large load of instant vacuum with VFD-E outstanding overload capacity.


It not only saves energy with built-in PLC function and mulli-step speed but also eliminates cost of an external controller.
