Description
XD1000 18.5kW 415V Variable Speed Drive – xD1000 Series VFD by Lauritz Knudsen
The Lauritz Knudsen XD1000-43P0-4B2111 is a 415V AC Variable Frequency Drive rated 18.5kW (Heavy Duty) / 22.0kW (Normal Duty) — this 18.5kW variable speed drive is part of the xD1000 AC Drive series from Lauritz Knudsen Electrical and Automation. Built on the same Frame S5 chassis as the 15kW model, this is now the highest-power model in the xD1000 lineup available at Stockhai. Full technical reference: lk-ea.com/cn/XD1000-43P0-4B2111.
Motor Control Modes
The XD1000-43P0-4B2111 supports multiple control algorithms to suit different load types: V/F Control (2 Point), Pump-optimized U2/F Control, Sensorless Vector Control (SVC), and Slip Compensation for improved speed accuracy under varying load — making it suitable for fans, pumps, conveyors, and general industrial motor control applications.
Built-in Braking Chopper
This model includes an integrated dynamic braking chopper as standard, enabling fast motor deceleration and controlled stopping without the need for an external braking unit — useful in applications requiring quick stops or frequent start/stop cycles.
Forced-Fan Cooling – Frame S5
As a Frame S5 unit, the drive uses forced-fan cooling (1 fan, minimum airflow 140 m³/h) to manage the higher heat dissipation at this power rating, maintaining reliable operation with acoustic noise kept to approximately 50 dBA.
Built-in Modbus RTU
Integrated Modbus RTU communication (RJ45 connector, 2-wire RS485, 4800–38400 bps) allows the drive to be connected directly into a PLC or SCADA-based automation network for remote monitoring, parameter configuration, and centralized control — without requiring an external communication module.
Applications
As an 18.5kW variable speed drive, it is well suited for large HVAC fans and pumps, water supply systems, compressors, conveyor systems, mixers, and general-purpose industrial motor control where a high-power 415V drive with robust overload capacity is required.

Note: This model shares the same Frame S5 chassis dimensions and weight as the 15kW model, but steps up to a heavier-duty circuit breaker (63A) and contactor (MO 70) plus a higher-rated 100A semiconductor fuse and a lower-value dynamic braking resistor (minimum 10Ω vs. 16Ω) to match its increased current handling. Per Lauritz Knudsen’s own product range specification, 18.5kW(HD) sits near the top of the entire xD1000 HD range (0.37–22.0kW).

FAQ
Q: Can this drive be used for pump and fan applications?
A: Yes, the built-in Pump U2/F control mode is specifically designed for variable-torque pump and fan loads.
Q: Does it need an external braking resistor unit?
A: No external chopper unit is required — the braking chopper is built into the drive; an external braking resistor (minimum 10Ω) can be added for higher braking duty if needed.
Q: What communication protocol does it support?
A: Built-in Modbus RTU is standard for integration with PLC/SCADA systems.
Summary
The Lauritz Knudsen XD1000-43P0-4B2111 is an 18.5kW(HD)/22.0kW(ND) 415V VFD on Frame S5 with built-in braking chopper, forced-fan cooling, multiple control modes, and Modbus RTU communication — currently the highest power model in the xD1000 series at Stockhai.
