PORTABLE SAFETY TRANSFORMERS 230V/24V

How to choose the right safety transformer?

A portable safety transformer is an electrical device designed to lower a high voltage (230V) to a safe voltage (24V LTV). It is specifically designed to avoid electrical hazards by providing reinforced insulation between the primary and secondary circuits. This type of transformer is widely used in environments requiring increased safety, such as construction sites, where workers and equipment must be protected against the risk of electric shock.

When to use a safety transformer or an isolation transformer?

The main role of the safety transformer is to ensure a reliable power supply while minimizing risks to users. By reducing voltage to a very low level, it protects operators and equipment against accidental electric shock. What's more, its design makes it possible to power a variety of devices while guaranteeing continuity of operations, even in demanding environments. This electrical separation is essential for maximum safety. In short, it combines safety, reliability and efficiency.

What's the difference with an isolation transformer?

An isolation transformer, although similar in design, differs in its main function. It doesn't necessarily reduce voltage, but creates galvanic isolation between input and output. This isolation protects sensitive equipment from electrical interference and overvoltage, while reducing the risk of short-circuiting. The safety transformer combines isolation and voltage reduction. This makes it perfect for environments requiring low voltage. These features enable it to be used in applications requiring fast, safe tbt.

When is an isolation transformer used?

An isolation transformer is mainly used in situations where the protection of sensitive electronic equipment is essential. In hospitals, for example, it supplies power to medical equipment while eliminating the risk of electrical interference. In industrial environments, it protects machines against overloads and guarantees stable operation. Unlike safety transformers, they are less frequently used on site, unless the sensitivity of the equipment requires it.

How to use a safety transformer

A safety transformer converts 230V to 24V (low-voltage). It's quick and easy to use: plug it into the mains and use the available sockets to power your low-voltage appliances. Some models feature reinforced housings for enhanced shock protection. Transformers are available with 1, 4 or 6 sockets, depending on your needs. For example, our 2500 VA 230/24V safety transformer offers 6 x 24V sockets.

Selection criteria for safety transformers

While using a transformer is straightforward, choosing the right model requires special attention. Determine your electrical power requirements: add up all the electrical powers of your appliances and add 140%. This figure represents a safety margin to prevent overheating. These steps will ensure optimum electrical distribution. To find out the power rating of a transformer, refer to its VA rating.

Another criterion to consider is mechanical resistance (IK) and protection index (IP). These elements ensure maximum reliability in the most demanding environments, such as industrial buildings.

In summary, to ensure optimal use, please take the following into account:

• Electrical power (expressed in VA): for example, the 2,500 VA model is ideal for energy-hungry appliances.
• Protection index (IP): determines resistance to dust and water. For example, an IP54 rating ensures watertightness for outdoor environments.
• Robustness (IK): necessary to withstand mechanical shocks on site.

Your industrial sites covered by our transformers

Labérine Énergie offers isolation transformers specially designed for industrial sites. For the entire range up to 3,500VA, they are housed in a butyl rubber enclosure. Above 3,500VA and up to 315KVA, they are protected by a sheet metal enclosure. These features enable you to supply your worksites with safe, high-powered power. With our portable or stationary safety transformers, you can supply your site lighting with 24 V (extra-low voltage) in complete safety.

For outdoor jobs, the weather is no problem, since our safety transformers are resistant to rain, dust and moisture. What's more, our units are relatively light and ergonomic, so you can transport them from one site to another with minimum effort.

Depending on the model you choose, our transformers offer a number of totally safe and efficient sockets. Our 2.5 kva 230V/24V transformer, for example, offers 6 CEE 16A 2P 24V sockets. But if your power requirements are more modest, opt instead for the 1,000 VA 230/24V model, which offers 4 sockets. Lighter in weight, this transformer also comes with a 3 m cable, so you can benefit from power on your worksite without any loss of voltage. Finally, all our transformers come with primary and secondary circuit breakers to guarantee the safety of your workers in all circumstances.

Our portable and stationary safety transformers

Labérine offers safety transformers for a wide range of applications , in both portable and stationary versions. Portable transformers are characterized by their light weight and compact design, making them easy to transport from one worksite to another. They are particularly well-suited to one-off jobs, flexible environments and emergency situations. These models are often equipped with ergonomic handles and a robust structure to withstand frequent movement and outdoor conditions.

Stationary transformers, on the other hand, are designed for fixed installation and long-term use. They are ideal for industrial sites, workshops or infrastructures requiring a stable, continuous power supply. These models often feature higher power ratings to meet demanding requirements, and a reinforced design to ensure optimum resistance in specific environments.

The choice between a portable or stationary model depends on the constraints of the project. If mobility and flexibility are essential, a portable transformer is the best choice. Conversely, stationary transformers are ideal for permanent installations where power and stability are paramount.

These two complementary options ensure that you'll always find a solution to your very low voltage (VLV) power supply needs, in complete safety.

Whether you need a safety transformer or an isolation transformer, our experts are at your disposal to guide you in your choice.
