DC VFD 3 Phase 380V 0.75kw, 1.5kw, 2.2kw, 4kw, 5.5kw, 7.5kw, 11kw, 15kw, 18kw, 22kw, 30kw, 37kw | Efficient Variable Frequency Drive

VFD 3 phase 380V is the right choice when you want to control motor speed instead of slamming every motor straight on line. This CNC drive range covers 0.75kW to 37kW, so it fits small workshop machines as well as larger pumps, blowers, conveyors and process lines. In Pakistan that matters because rough starts waste power, shock belts and couplings, and create nuisance trips on weak panels.

This is not a product to buy by guesswork. A VFD must match motor kW, supply voltage and duty pattern. A 2.2kW drive for a packaging machine in Lahore is a different job from a 22kW drive on a textile line in Faisalabad. The point is simple: smoother starting, controllable speed and less mechanical abuse.

This description uses only data published on the live product page plus carefully separated official CNC family data where it helps the buyer. Exact input current, output current, braking resistor data, terminal map and dimensions for every local variant are not fully published on the Pakistan product page and have not been guessed.

Applications in Pakistan

The best use of a VFD is proper motor control. In Faisalabad that often means textile and process machines that do not need full speed all day. In Karachi, pump duty and HVAC are common reasons to move from basic starting to variable speed control. In Lahore and Sialkot, workshop and production lines often use drives to reduce start shock and get steadier operation.

• Water pumps where full-speed starting creates hammer, pressure spikes or panel disturbance
• Blowers and exhaust systems where speed needs to match real demand
• Conveyors where slow ramp-up protects belts, couplings and gearboxes
• Packaging and process machines where the operator needs more control than simple ON/OFF
• Commercial HVAC systems in Islamabad and Rawalpindi where controlled motor operation helps comfort and uptime
• Workshop machinery where reduced start shock can make the whole setup feel less rough

Sizing and Selection Guide

Start with the motor nameplate, not the salesman’s guess. Match the supply first, then the motor kW, then the duty. A lightly loaded fan and a high-inertia conveyor do not behave the same way. If the load is hard to start or the site is unusual, do not treat it like a standard pump job.

CNC vs Competitors

What This Product Does NOT Protect Against

A VFD is not a replacement for every protection device in the panel. It does not replace upstream short-circuit protection, proper earthing, surge protection, phase monitoring where needed, or correct panel cooling. It also does not fix an undersized motor, a damaged bearing, a broken process machine or a badly wired control circuit.

• It does not replace the upstream circuit breaker or MCCB.
• It does not replace a proper surge protection device in a rough supply environment.
• It does not replace a phase sequence relay where phase loss or reversal is a real risk.
• It does not replace suitable contactors and overload coordination where the panel design needs them.

Installation Guide

Drive installation is not just “mount it and run it.” First confirm the motor nameplate, available supply and the actual duty of the machine. Second, mount the VFD in a clean panel with sensible airflow. Third, use correct upstream protection and proper grounding. Fourth, program the basic motor parameters and ramp times carefully instead of leaving everything at random defaults. Fifth, test under real load and watch current, acceleration behaviour and motor temperature before calling the job complete.

In Pakistan, panel heat is often ignored. That is a mistake. A drive that sits in a sealed dusty cabinet beside hot contactors in June will not behave the same way as a drive mounted in a ventilated indoor control panel. If the enclosure is crowded, add space planning and cooling into the job from day one.

Frequently Asked Questions

1) What is the main reason to install a VFD instead of a normal starter?

The main reason is control. A normal starter gives full-speed starting. A VFD lets the motor ramp up, slow down and run at the speed the process actually needs.

2) Can this CNC VFD save electricity?

Sometimes yes, especially on fans and pumps where speed can be reduced instead of throttling flow. On fixed-load machinery, the main gain may be process control rather than dramatic savings.

3) Which kW size should be selected?

Start with the motor nameplate. Match the drive to the motor kW and supply system. If the load is heavy, high inertia or hard to start, do not choose on kW alone.

4) Is this VFD suitable for textile machinery in Faisalabad?

Yes, provided the motor and duty match the selected kW size. Textile applications often benefit from smoother starting and adjustable process speed.

5) Can this be used for pumps in Karachi or Peshawar?

Yes. Pump duty is one of the common VFD jobs. The correct size still depends on the motor nameplate and the load.

6) Does the local product page publish full current and terminal details?

No. The local page publishes the voltage class, kW range and live variant prices. Some deeper datasheet values are not fully listed there, so they have not been guessed.

7) Should a surge protector be added with a VFD panel?

Often yes. If the panel is exposed to unstable incoming supply or surge risk, an SPD is a sensible add-on.

8) Is this better than buying the cheapest available imported drive?

For many buyers, yes, because this listing gives a visible kW range and live local pricing. The cheapest drive can look attractive at first but often leaves the buyer with thinner support and weaker documentation.

If you need a 3 phase 380V VFD in Pakistan, this CNC range gives you a practical spread from 0.75kW up to 37kW with live local pricing already visible on the product page. The safer buying approach is to match the drive to the motor and duty instead of buying by rough guess.
