Purpose

This general-purpose variable frequency drive is designed for regulating the rotation speed of an AC electric motor with a maximum power output of 22 kW. This unit is only suitable for general ventilation systems.

Features

The drive construction prevents forced air flow passage through its internal electronic components. The internal circuit boards of are well-protected.

Inputs and outputs

• 5 programmable digital inputs
• PNP/NPN logic
• 20-5000 Hz pulse input
• One 0-10 V or 0-20 mA analogue input
• One 0-20 mA analogue input
• Thermistor input (analogue or digital)
• 1 analogue output
• 1 relay, 240 V, 2 A
• RS 485
• Modbus RTU

Filter

The unit features an integrated HF filter which blocks RF interference from the motor and enables the use of a shielded cable up to 15 m long or unshielded cable up to 50 m long as per the applicable EU regulations.

Installation

Back-to-back installation for space savings. Thanks to a compact design the drives can be mounted immediately next to one another without any performance penalties.
