Danfoss 134N0813 at a glance

The Danfoss 134N0813 is a 3.0 kW VLT HVAC Drive FC 102 for 3 × 380–480 V AC supplies, made for the fans, pumps and compressors in building services. It is a frame A2, IP20 / chassis unit, built for mounting inside a control panel or enclosure.

This configuration has RFI class A1/B (C1), safe Stop, no brake chopper, a numeric LCP 101 control panel, and a BACnet MCA 109 fieldbus card. The full type code is decoded alongside the FAQs.

Sizing and installation

  • Enclosure: IP20 / chassis — built for mounting inside a control panel or enclosure.
  • EMC: RFI class A1/B (C1). Check the permitted screened motor cable length in the Danfoss FC 102 Design Guide.

FC 102 features for HVAC

  • Built-in RS-485 protocols: Danfoss FC, Modbus RTU, BACnet MS/TP, Metasys N2 and FLN Apogee — connects to most building management systems without an option card.
  • Fire Mode keeps the drive running during an emergency, for example to keep smoke-extract fans turning.
  • Automatic Energy Optimisation (AEO) cuts motor losses at part load — Danfoss quotes a further 5–15% saving.
  • Pump and fan functions: sleep mode, dry-pump, end-of-curve and broken-belt detection, plus a built-in cascade controller for pump sets.
  • Built-in DC coils limit mains harmonics (EN 61000-3-12).
  • Smart Logic Controller for simple sequencing without a PLC.

Where the energy saving comes from

Centrifugal fans and pumps follow the affinity laws: absorbed power falls with the cube of speed. Running at 80% speed needs roughly half the power of full speed (0.8³ ≈ 0.51, before motor and drive losses) — which is why speed control pays back faster on fans and pumps than almost any other load.

Frequently asked questions

Which communication protocols does it support?

This unit is fitted with a BACnet MCA 109 card, in addition to the built-in RS-485 protocols: Danfoss FC, Modbus RTU, BACnet MS/TP, Metasys N2 and FLN Apogee.

Does this drive need to go in an enclosure?

Yes. IP20 / chassis drives are designed to be mounted inside a control panel or enclosure. For wall mounting without a panel, choose an IP55 or IP66 version.
