Product Description:

The 134N8585 is an AC variable frequency drive from Danfoss for the VLT FC 102 HVAC Drives series. It controls fan and pump motors in heating, ventilation, and air-conditioning systems, allowing motor speed to track changing demand. That control method can reduce energy use, lower mechanical stress, and improve part-load operation in building services.

It accepts 380 to 480 VAC input, which allows connection to common building power without a separate transformer. Because it uses three-phase power, the DC bus remains stable under normal operating load and supports consistent motor performance. The enclosure carries an IP20 chassis rating, so the unit is intended for installation inside a ventilated cabinet where basic finger protection is maintained.

Networking is handled by the embedded EtherNet/IP MCA 121 option, which supports communication with building automation systems for monitoring and control. The MCB-109 I/O, RTC backup board adds terminals and helps preserve clock functions during short power interruptions. A removable graphical local control panel provides on-door access to trends and parameter changes, while the integrated RFI filter helps limit electromagnetic emissions. The drive uses normal cabinet mounting for A, B, and C frames, has standard cable entries, and is built without a brake chopper.

Wake Industrial keeps this drive in stock for dispatch. Same-day shipping is available on qualifying orders, which can help reduce downtime when a replacement is needed quickly. Quotations remain valid for 30 days, and the chat tool available on the website can help with questions about type codes or fault codes.
