Overview Variations

What are Frequency Inverters for?

Frequency Inverters allow you to control the speed and power of the electric motor in your pump by altering the voltage and magnitude.

The ACS355 series, manufactured by ABB (market leader in the drive systems market), is of the highest quality with great functionality and available in 2 different standards.

Loose – to be installed by the customer
Pre-Installed in a cabinet including control system & calibrated

Key Features of the ACS355 Frequency Inverters:

Exceptionally compact & uniform design
Operating LCD display in 16 different languages
Quick & Easy commissioning with pre-configured application macros
Extension & Fieldbus Modules are optional
Instructions & Catalogues in multiple languages
Dedicated Tapflo Internal Technical Support available

Key Functions of the ACS355 Frequency Inverters:

Built in Dry-Run Protection for Centrifugal Pumps
2 Built-In PID Controllers for simple pressure or flow control without external controllers
Safe torque-off function (SIL3) as standard
Built-on C3 EMC Filter and brake chopper
Sensorless Vector Control
150% overload capacity
