Description
XD1000 4kW 415V Variable Speed Drive – xD1000 Series VFD by Lauritz Knudsen
The Lauritz Knudsen XD1000-12P1-4B2111 is a 415V AC Variable Frequency Drive rated 4.00kW (Heavy Duty) / 5.50kW (Normal Duty) — this 4kW variable speed drive is part of the xD1000 AC Drive series from Lauritz Knudsen Electrical and Automation. Built on Frame S3, this is currently the largest and highest-power model in the xD1000-02P3 to 12P1 lineup available at Stockhai, offering higher current handling and a heavier-gauge power terminal design to match its increased output.

Motor Control Modes
The XD1000-12P1-4B2111 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 S3
As a Frame S3 unit, the drive uses forced-fan cooling (1 fan) to manage heat dissipation at this higher power rating, maintaining reliable operation with acoustic noise kept to approximately 50 dBA.
Built-in Modbus RTU
Integrated Modbus RTU communication 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 a 4kW variable speed drive, it is well suited for HVAC fans and pumps, water supply systems, compressors, conveyor systems, mixers, and general-purpose industrial motor control where a mid-to-high power 415V drive with robust overload capacity is required.

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 can still 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 XD1000-12P1-4B2111 is a 4.00kW(HD)/5.50kW(ND) 415V VFD on Frame S3 with built-in braking chopper, forced-fan cooling, multiple control modes, and Modbus RTU communication — the highest power model currently listed in the xD1000 series at Stockhai.
