Product Overview
The Control Techniques INL401 is a three-phase AC input choke developed for Unidrive SP drive installations using a 380–480 VAC ±10% three-phase supply.
An AC input choke provides impedance between the incoming electrical supply and the drive, helping smooth the current drawn by the drive. This can help reduce harmonic distortion introduced into the upstream electrical network and provide additional protection for the drive's input rectifier against supply-side transients.
The INL401 is particularly useful in installations where upstream electrical equipment may be sensitive to supply disturbances or where additional harmonic mitigation is required. It provides a dedicated external input-choke solution for compatible Unidrive SP installations.
Before installation, the choke should be checked against the specific Unidrive SP drive model and the manufacturer's installation requirements to ensure the correct input-choke arrangement is used.

Frequently Asked Questions
What does the Control Techniques INL401 input choke do?
The INL401 helps smooth the current drawn from the incoming AC supply, reduce harmonic distortion fed back into the electrical network and protect the drive's input rectifier from supply-side transients.
Which drives is the INL401 designed for?
The INL401 is specified for the Control Techniques Unidrive SP drive range.
What voltage supply is the INL401 designed for?
It is designed for 380–480 VAC ±10% three-phase supplies.
Is the INL401 a genuine Control Techniques accessory?
Yes. The INL401 is supplied as a genuine Control Techniques manufacturer accessory through General Tech Services LLC.
Where is the INL401 installed?
The input choke is installed on the AC supply side of the drive, following the manufacturer's wiring and installation requirements.
Do I need an external input choke if the drive already has an internal choke?
Some drives may include an internal DC choke, while an external AC input choke can be specified separately for additional harmonic mitigation or supply-side protection. The correct arrangement depends on the specific drive and installation. Contact our team to confirm the requirement.
Is the INL401 compatible with other Control Techniques drive families?
The INL401 is specified for the Unidrive SP range. For other Control Techniques drive families, contact General Tech Services LLC to confirm the correct input-choke part number.
