Description
XD2000-120P-4B1221 — 45kW(HD)/55kW(ND) Three-Phase Variable Frequency Drive (415V)
The Lauritz Knudsen xD2000 XD2000-120P-4B1221 is a 45kW/55kW 415V VFD built for fan, pump, compressor, and other non-regenerative process applications on a 380–460VAC (-15/+10%), 3-phase, 50/60Hz supply. It combines a compact Frame 5 footprint with an inbuilt EMC filter, galvanic isolation, and (from 4kW ND onward) a built-in DC reactor for reduced harmonics and longer motor cable runs. Explore the complete range in our Lauritz Knudsen variable frequency drives collection.
45kW/55kW 415V VFD – Control & Motor Compatibility
The xD2000 supports V/F control (5-point), Slip Compensation, quadratic V/F energy-saving, and Open Loop control of Permanent Magnet synchronous motors. Overload capacity is 150% of rated current for Heavy Duty use and 110% for Normal Duty use, and the output frequency range spans 0.5–500Hz. This 45kW/55kW 415V VFD is a strong fit for fans, pumps, compressors, and general utility process applications that do not require regenerative braking.
45kW/55kW 415V VFD – Pump & Fan-Specific Features
Built-in PID control (AHU, fan, pump, compressor) supports 4 preset PID references, PID wake-up/sleep with Sleep Boost, and predictive speed (pre-PID frequency). Pump & compressor specific logic adds lead (master) and auxiliary pump selection with fixed and variable speed, FIFO/FILO staging, and booster-pump control with staging and destaging. Stall prevention (deceleration ramp adaptation and current limiting), skip frequency, catch-on-the-fly (flying start), and DC braking during stopping round out the application toolkit.
45kW/55kW 415V VFD – Built-in Modbus & Optional Profibus DP
A front-face RJ45 port gives native 2-wire RS485 Modbus RTU connectivity (4800–38400 bps), so the XD2000-120P-4B1221 links directly to a PLC, HMI, or SCADA system. An optional Profibus DP card (9-pin Sub-D, 9.6–12000 kbps with automatic baud-rate detection) adds native drive profile support (CiA®402) and PROFIdrive, with quick setup from the drive side and support for two masters (MS0/MS1). Detachable, IP21-rated basic LCD keypads (4-line, white backlight, 6 languages, store/download configurations) are standard, with an advanced graphical LCD keypad available as an option.
45kW/55kW 415V VFD – Applications
This 45kW/55kW 415V VFD is widely used for HVAC fans and AHUs, water and booster pumps, compressors, and other non-regenerative utility and process applications across buildings, water treatment, and light industry. Its enclosure is IP20 (IP4X on top with the vent cover), and the inbuilt EMC filter complies with IEC/EN 61800-3 Category C3 in Environment 1 or 2 for CE marking, with a maximum shielded cable length of 50m.
