Product Description:

The 136U3388 is a variable frequency drive from Danfoss in the VLT FC 102 HVAC Drives series. It modulates fixed-frequency input power to control motor speed for fans, pumps, and compressors in building automation systems. That control helps ventilation and chilled-water equipment match demand more closely and reduce unnecessary energy consumption.

An integrated MCA 125 BACnet/IP option allows native BACnet communication, so setpoints and status values can move across the network without a separate gateway. The MCB-109 I/O card with RTC backup adds terminals and preserves time data during outages, which helps scheduled control sequences restart correctly. The drive accepts 380 to 480 VAC and uses three-phase power to deliver balanced motor currents across common commercial distribution systems.

A chassis enclosure rated IP20 chassis is intended for protected installation inside an electrical cabinet with managed airflow. Operators use the graphical local control panel to review parameters and trend data directly at the drive. An integrated RFI filter reduces conducted emissions, while normal cabinet mounting for A, B, and C frames supports standard panel layouts. The unit uses a non-coated PCB, which is suitable for clean electrical rooms where conformal coating is not required.

Wake Industrial stocks this drive and can arrange same-day shipping for urgent orders. Quotations remain valid for 30 days, which can help buyers align purchasing with maintenance schedules. For questions about fault codes or parameter groups, customers can use the chat tool available on the website. It is available for fast replacement in time-sensitive HVAC service situations.
