Product Description:
The 131B9890 is a variable-frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. It modulates three-phase induction motors in air-handling units, chillers, and pumps, allowing building-automation systems to match fan or compressor speed to real-time load demands and conserve energy.
The drive is rated at 37 kW (equivalent to 50 hp) and accepts mains supplies from 380 - 480 VAC three-phase networks. Continuous input current is 59 A, while the power stage delivers a steady 65 A to the motor and can surge to 71.5 A for short acceleration intervals. Losses at rated load are limited to 739 W, supporting efficient cabinet thermal management. An integrated RFI filter helps meet EMC emission class EN 55011 Class A2, and the product includes no brake chopper because HVAC fans rarely require dynamic braking. Power is processed through an internal rectifier; there is no additional mains option module.
Mechanically, the enclosure is certified to IP55 / Type12 Backplate and measures 680 mm H × 308 mm W × 310 mm D with a maximum mass of 45 kg, allowing installation on Frame A5, B, or C backplates in open-drive panels. The unit ships with a graphical local control panel (LCP), two relay outputs, and an enclosure size code C1. Standard cable entries form Adaptation A, while Adaptation B and all A, B, C0, C1, D, and Mains options are omitted, reflecting a streamlined HVAC-centric build. The printed circuit boards are not coated, the software is the latest standard release with a standard language pack, and the series identifier is 102 within the VLT HVAC Drive product group.
