DANFOSS MCE101 175U3104

Danfoss VLT MCE101 Brake Resistor

Description

The Danfoss VLT MCE101, part number 175U3104, is a high-quality brake resistor designed for use with Danfoss VLT series frequency converters. It plays a critical role in applications with high inertia or frequent, rapid decelerations by safely dissipating regenerative energy from the motor. This prevents over-voltage faults on the DC-link of the drive, ensuring stable and reliable operation. Its robust construction with an aluminum heatsink provides excellent thermal performance.

FAQ

What VLT drives is this MCE101 resistor compatible with?

It is generally compatible with smaller Danfoss VLT series drives like the FC 51, FC 202, and FC 301/302. However, you should always verify compatibility and proper sizing in the specific drive’s hardware or design guide.

What is the purpose of the 10%/40% duty cycle rating?

This rating indicates the resistor’s ability to handle high peak power for short durations, which is typical during motor braking. It means the unit can safely dissipate 2800W for 10% of a 30-second cycle, or 700W for 40% of that same cycle, without overheating.

What are the key considerations for installation?

Ensure there is adequate ventilation and clearance around the aluminum heatsink, as it is designed to get hot. Use appropriately gauged wiring for the expected peak current and ensure all electrical connections are secure to prevent hazards.
