Product Description:

The 134N0046 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. It regulates motor speed in air-handling units, chillers, and pump groups so airflow or pressure can be controlled accurately while energy use is reduced. This makes it well suited for commercial and industrial building systems that need stable HVAC performance during changing load conditions.

Electrical compatibility includes 380-480 VAC on a three-phase power supply, and the IP20 chassis is intended for use inside standard control cabinets. A built-in RFI filter reduces conducted emissions, and the optional Modbus TCP MCA 122 interface enables Ethernet-based supervision. Because the design is built without a brake chopper, without a B option, and without a mains option, regenerative energy must be handled by external equipment.

Uptime support is provided by the MCB-107 24 V DC backup board, which helps the control electronics ride through brief power dips and maintain parameter retention. Operators adjust settings through a graphical local control panel, which gives direct access to parameter changes and operating status. The drive uses an uncoated PCB, so it is best suited to filtered environments where airborne contaminants are controlled.

Wake Industrial stocks this drive and can arrange same-day shipping options for urgent orders. Each purchase is backed by a 1-year warranty. Customers can use the chat tool available on the website for questions about type codes, fault codes, or general specifications when quick clarification is needed during maintenance planning and routine service work at busy facilities.
