Product Description:

The 136U0576 is an AC motor controller produced by Danfoss for the VLT FC 102 HVAC Drives series. It is intended for building-automation panels that regulate pump and fan speed to balance airflow or water circulation while reducing energy use. The controller supports stable motor operation in commercial HVAC systems where efficient variable-speed control is important.

This drive accepts a mains supply of 380 to 480 VAC, allowing it to operate on common 50 Hz and 60 Hz utility networks without a separate transformer. It is built for three-phase power, so the rectifier and inverter can deliver balanced output to compatible induction motors. The unit carries an IP20 / Chassis protection rating, which makes it finger-safe while still requiring installation inside a suitable enclosure. An integrated RFI filter helps reduce conducted emissions and supports compliance with EMC requirements in commercial environments.

User interaction is handled through a detachable graphical local control panel that displays operating speed, temperature, and alarm information on a backlit screen. Time-based scheduling is available with the installed MCB-117 real-time clock option, which supports night setback and weekend shutdown routines. The drive uses normal cabinet mounting for A, B, and C frames, which matches standard switchboard layouts used in HVAC applications. Its uncoated PCB design suits climate-controlled mechanical rooms where airborne contamination is limited.

Wake Industrial stocks this drive and offers same-day shipping. Each unit includes a 1-year warranty, and quotations remain valid for 30 days. The chat tool on the website answers general type-code and fault-code questions.
