V1k provides Motor Protection by limiting voltage spikes below 1,000 volts for long lead applications

  • Greatly extends the life of the motor and cable

  • Specific applications can reach 3,000 feet

  • 30% reduction in common mode current

The V1k is the newest generation of the KLC dv/dt output filter series. V1k filters are UL Listed and available in Open, Type 1 and Type 3R packaging configurations. The V1k supersedes the KLC product line. The V1K prevents voltage spikes from exceeding 1,000 V up to 2,000 feet and limits dv/dt to less than 1,000 V/ μs. The product has been used successfully in applications up to 3,000 feet depending on cable and VFD sizes.

V1k Specifications:

Efficiency: > 98%

Insulation Rating: 600V

Class Insulation Class: Class H (180°C) or Class R (220°C)

Ambient Temperature: 40° C

Maximum Altitude: 2,000 meters (6,000 feet)

Derating necessary above 2,000 meters

Agency Approvals: cUL, UL

Lead Length: Specific applications can reach 3,000 feet (consult factory for applications above 1,500 feet)

V1k dV/dT Performance Guarantee, What is dV/dT?

Properly sized and applied, TCI guarantees that the V1k will limit motor terminal peak input voltage to 150% of the bus voltage with a wire lead length of 1000 feet and a carrier frequency of 4 kHz. Maximum lead length and carrier frequency can vary depending on wire lead type. If a properly selected, installed, and loaded V1k filter fails to meet the guaranteed performance levels, TCI will provide the necessary components or replacement filter at no additional charge. TCI does not take responsibility for additional installation or removal costs, to include, but not limited to, replacement of third party equipment.

Minimum System Requirements for Guarantee

In order to achieve the performance levels as stated in this guarantee, the electrical system must adhere to the following: The V1K must be sized at no more than 110% of the drive output current rating. The V1K must be sized to have regular line current loading of no less than 25% of its current rating. If the load has a potential for overhauling, the drive must be equipped with braking resistors or other features limiting bus voltage to no more than the level of the peak line voltage. The V1K must be wired no more than 10 feet from the drive.
