Product Description:
The 134U4499 is a variable frequency drive manufactured by Danfoss and positioned within the VLT FC 102 HVAC Drives series. Falling under the VLT HVAC Drive product group, this unit is engineered for integration in air-handling units, pumps, and other building-services equipment where closed-loop speed regulation is required. By varying motor frequency, it enables accurate airflow or pressure control while minimizing energy consumption and mechanical stress on connected machinery.
Electrical characteristics start with a supply range of 380 – 480 VAC, suited to three-phase distribution panels. The unit accepts three-phase power, which supports balanced current draw and reduced harmonic content. Its enclosure carries an IP20 / Chassis rating, meaning finger protection is provided, but the drive must be mounted inside a control cabinet for environmental protection. Communication with supervisory systems is available through the BACnet MCA 109 A-option card, and field I/O expansion is provided by the MCB-105 Relay Card installed in the B-option slot. Standard cable entries are pre-machined in the housing, and there is no additional mechanical adaptation on the B side, so installation is limited to routing conductors. An internal RFI filter attenuates conducted emissions, while the design omits a brake chopper because safe-stop braking is not required for typical HVAC loads. Normal cabinet mounting across A, B, and C frame sizes supports straightforward placement.
Routine service is simplified by the front-mounted graphical local control panel, which allows parameter changes without external tools. The drive uses the Standard Language Pack for its interface and the latest standard software release, so no additional C-option software is loaded. The unit uses uncoated PCBs, reflecting the intended clean-cabinet environment. There are no C0, C1, D, or mains options installed, and the safe-stop brake interface is unused. The drive follows the 102 series identifier and uses first-entry standard cable glands to complete wiring.
