Power Supply
Power supplies are essential components used to convert and deliver electrical energy safely and efficiently to various electrical and electronic devices. Choosing the right power supply depends on the required voltage, current, and power for each application, ensuring reliable performance and safety in industrial, commercial, and residential environments.

Industrial Power Supplies and Transformers
Henvi offers a specialised range of power supplies and transformers, essential components for ensuring that your equipment receives the correct voltage with maximum stability. Whether for powering DC control circuits or for AC voltage isolation and conversion, our solutions are selected to deliver high energy efficiency and long-term reliability.
Power Supplies for Automation (AC/DC)
In modern automation, voltage precision is non-negotiable. Our catalogue includes:
- DIN Rail Power Supplies: Compact and easy to install, ideal for powering PLCs, sensors and HMI interfaces.
- Standard Voltages: Models available in 12V, 24V and 48V DC, with different current ratings (Amps) to suit your system load.
- Integrated Protection: Equipment with protection against short circuits, overloads and overvoltage.
Control and Isolation Transformers
For applications requiring changes in AC voltage levels, we offer robust transformers:
- Control Transformers: Essential for separating power and control circuits, ensuring galvanic isolation.
- Input/Output Versatility: Solutions for converting 400V or 230V to the most common control voltages on the market.
- High-Quality Construction: Durable windings and insulating impregnation to minimise losses and acoustic noise.
Why Trust Henvi for Your Power Conversion Needs?
As a close and reliable partner, Henvi understands that a power supply failure can bring an entire production line to a standstill. That is why we work exclusively with manufacturers that guarantee high MTBF (Mean Time Between Failures). When you purchase from Henvi, you benefit from specialised technical support to calculate the power required for your installation, preventing overheating and ensuring the longevity of your electronic components.
Frequently Asked Questions About Power Supplies and Transformers
What is the difference between a power supply and a transformer?
A transformer changes the voltage of alternating current (AC) without changing its frequency. A power supply generally converts the mains AC into stable direct current (DC), which is used by most electronic and automation components.
How do I size the power rating (W) of a power supply?
You should add up the consumption of all devices that will be connected to the power supply and add a 20% to 25% safety margin. This prevents the power supply from operating at its limit, reducing the heat generated and extending its service life.
What is an isolation transformer used for?
An isolation transformer electrically separates the load circuit from the power supply network. This is a critical safety measure for protecting operators and sensitive equipment against electric shocks and electrical interference.
