⚡ Key Features

Rated for a 18.5 kW motor — adjustable output frequency from near 0 to 50/60 Hz gives stepless speed control for pumps, fans, compressors, and conveyor drives.
Soft-start acceleration ramp — limits motor starting current to ~1.5× FLC vs. the 6–7× FLC of DOL starting; eliminates mechanical shock on gearboxes, belts, and couplings and reduces peak demand charges.
Built-in electronic motor protection — overload, phase-loss, overvoltage (+10%), undervoltage, and short-circuit protection without additional external relays.
Manufactured to IEC 61800-5-1 (safety) and IEC 61800-3 (EMC) — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified where applicable — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised XD1000-43P0-4B2111 product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.
Worldwide export available — UAE, Singapore, UK, USA, Sri Lanka & more. Contact +91 94814 00316 for bulk pricing and international shipping.

❓ Frequently Asked Questions

Q: Can the XD1000-43P0-4B2111 be used to control a 18.5 kW motor with soft start and variable speed?

A: Yes. This VFD is rated for a 18.5 kW motor load and provides stepless speed control from 0 to rated frequency (typically 0–50 Hz). The soft-start ramp eliminates mechanical shock and reduces starting current from typically 6–7× FLC to just 1–1.5× FLC. Ensure the motor cable length does not exceed the VFD manufacturer’s maximum (typically 50–100m without output filter) to avoid insulation stress.

Q: Does the XD1000-43P0-4B2111 require an input line reactor or output filter for protection?

A: For installations with poor power quality (voltage spikes, harmonics), an input line reactor (3–5% impedance) extends the XD1000-43P0-4B2111’s life by reducing diode stress and lowering harmonic injection. An output dV/dt filter is recommended when motor cable exceeds 50m to prevent reflected wave damage to motor insulation, especially on older motors not rated for VFD use.

Q: Can the XD1000-43P0-4B2111 run a standard squirrel-cage induction motor without modification?

A: Yes — standard squirrel-cage induction motors rated for 415V 50Hz can be driven by this VFD. However, at low speeds (<20 Hz), motor cooling is reduced because the shaft-mounted fan slows down. For extended low-speed operation, fit a separately powered external cooling fan on the motor, or use a motor specified for inverter duty.

Q: Does the XD1000-43P0-4B2111 inject harmonics into the supply and is a line reactor required?

A: VFDs including the XD1000-43P0-4B2111 generate harmonic currents (primarily 5th and 7th order) due to their diode rectifier front-end. In installations where total harmonic distortion (THD) is a concern — such as facilities with sensitive medical or measurement equipment, or where multiple large drives share a common bus — a 3% or 5% impedance line reactor on the input significantly reduces harmonic injection and protects the drive’s DC bus capacitors from voltage spikes. Check if your site’s power quality specification sets a THD limit.
