Product Description:

The 134L0931 AC drive is manufactured by Danfoss for the VLT FC 102 HVAC Drives series. It regulates fan, pump, and compressor motors so building systems can manage airflow, temperature, and energy use more precisely. The unit is intended for commercial and industrial HVAC cabinets where dependable variable-speed control is required.

The drive accepts 380 - 480 VAC on a three-phase power supply, which suits common facility distribution systems. An integrated RFI filter helps the unit meet electromagnetic compatibility requirements in controlled cabinet environments. The D option includes an MCB-107 24 V DC backup, allowing control electronics to remain powered during short mains interruptions. The enclosure carries an IP20 / Chassis rating, so it is meant for protected installation inside switchgear.

Because there is no brake chopper, braking energy must be managed by the system instead of inside the drive. The housing measures 268.0 mm in height, 205.0 mm in depth, and 90.0 mm in width, giving it a compact cabinet footprint. A total weight of 4.09 kg keeps handling straightforward during panel assembly. Standard cable entries and the front graphical local control panel support routine setup and parameter access.

No A, B, or mains option boards are installed, and software, C0, and C1 option modules are also absent. Conformal PCB coating is not applied, and adaptation B is not used. Wake Industrial offers same-day shipping options, keeps quotations valid for 30 days, and provides the chat tool available on the website for questions about fault codes or type-code details.
