Speciﬁ cations

Options

A wide range of HVAC options are available mounted and tested

from factory or as plug-and-play options for update.

• General purpose I/O

3 digital inputs, 2 digital outputs, 1 analog current output,

2 analog voltage inputs

• Relay outputs

3 relay outputs

• Analogue I/O

3 Pt1000 / Ni1000 inputs, 3 analog voltage outputs

• External 24 VDC supply

24 VDC external supply can be connected to supply

control- and option cards

• Brake chopper

Connected to an external brake resistor, the built in brake chopper

limits the load on the intermediate circuit in case the motor acts as

generator.

Danfoss Drives oﬀ ers a wide range of external power options for use

together with our drive in critical networks or applications:

• Advanced harmonic ﬁ lters:

For critical demands on harmonic distortion

• dv/dt ﬁ lters: For special demands on motor isolation protection

• Sine ﬁ lters (LC ﬁ lters): For noiseless motor

HVAC PC software

• MCT 10

– ideal for commissioning and servicing the drive

• VLT HVAC Planet

– an interactive design guide including application examples.

• VLT Energy Box

– comprehensive analysis tool to calculate the value of energy savings

in the application and the pay-back time of the drive.

• MCT 31

– harmonics calculations tool
