Product Description

As a quality conscious enterprise in this field, we are engaged in providing premium class ACS 550 Variable Frequency Drives. The offered drives are successfully manufactured using fine quality components and modish techniques by dexterous troop of professionals. Highly demanded to eliminate the need for reversing starter as well as expensive mechanical drive components such as gearbox, these drives are operated with configural fans and pumps to reduce the consumption. These ACS 550 Variable Frequency Drives can be availed from us at economical prices.

Key points:

  • Strong construction
  • Available with different specifications
  • Flawless finish
  • Low power consumption

Energy efficiency counters

Several counters to illustrate saved energy (kWh), carbondioxide emissions (CO2) and cost in local currency.

Shows direct impact on energy bill and helps control operational expenditure (OPEX).

Load analyzer

Load analyzer saves process data, such as current and torque values, which can be used to analyze the process and dimensioning of the drive and motor.

Optimized dimensioning of the drive, motor and process.

FlashDrop tool

Faster and easier drive set up and commissioning

Patented, fast, safe and trouble-free parametrization method without electricity

Assistant control panel

Two soft-keys, function of which changes according to the state of the panel

Built-in help function via dedicated button

Real-time clock, allows timed tracing of faults and setting of parameters to activate at various times of day

Changed parameters -menu

Easy commissioning
