VFD frequency converter 7.5kW 220V 380V triphase engine speed regulator

The VFD frequency converter is a professional electrical equipment to regulate the speed and power of a three-phase engine. This 7.5 kW converter is compatible with 220V and 380V network voltage and is therefore suitable for industrial and domestic power systems. The VFD-frequency converter reduces energy consumption, increases engine performance and extends its service life. It is ideal for controlling pumps, fans, spinning engines and other adjustable speed programs.

VFD frequency converter - main features

• Anal entrance 4- 20mA / 0- 10V — Allows connection of various sensors and control devices, enabling precise engine regulation based on real-time signals.
• Fixed pressure pump control - with PID function and pressure sensor, you can automate water supply systems to prevent swings and pressure fluctuations.
• Relay exit - integrated internal relay allows direct control of additional devices or signalling systems according to the status of the frequency converter.
• Support for rotary engines — Specialized configuration with up to 400Hz frequency, suitable for setting precise rotational speeds in machines and production lines.
• Universal three-phase exit - convert one-phase 220V or three-phase 380V into three-phase 220V / 380V compatible with any industrial engine.
• Easy installation scheme - a clear external connection diagram and terminal diagram makes installation simple even for beginners.
• High-quality electronics - reliable portable backhaul conversion with thermal protection and short-circuit protection guarantees long-term operation.

Buyer questions

Q: Does the VFD frequency converter work with my existing engines?
Yes, if your engine is three-phase and has a nominal power of not more than 7.5 kWConverter supports 220V / 380V tripping and single-phase input modes. If the engine is less than 7.5 kW, the converter will be ideal. We recommend choosing one step more power than your engine requirements.

Kl: How to connect the pressure sensor to a constant pressure pump?
The pressure sensor is connected to an analogue input of 4-20 mA or 0-10V. The frequency converter shall have an embedded PID function which automatically adjusts the engine speed at the specified pressure. The configuration is performed through the settings menu using the control panel.

Q: What is the duration of delivery and can I return?
The standard delivery from China hits 15-30 days. The guarantee shall be granted for 12 months from the date of purchase. If the product was damaged or incompatible, you can return it, but the buyer pays the customs duties. Contact our emergency services during mediation.

The VFD frequency converter is an investment in energy efficiency and engine performance. If you use triple engines and want to reduce costs, this converter is the ideal solution. Reliable, compact and easy to use, the VFD frequency converter will become your main tool.
