Portable transformers - an essential tool in the electrical industry

Portable transformers are a key piece of equipment for every electrician.   At Onninen we perfectly understand the needs of professionals in this field.   Our many years of experience allow us to offer the highest quality equipment. Portable transformers are used in many situations. They are useful both on construction sites and during home repairs. Their mobility is a huge advantage in everyday work.

Our offer includes a wide selection of portable transformers. Models with different power and parameters are available. We often come across questions about selecting the right device. That is why our experts will be happy to advise you on choosing the optimal solution. We pay special attention to the safety and reliability of the equipment.

Types of portable transformers available at Onninen

Our assortment includes various types of portable transformers.   We offer both single-phase and three-phase models.   We especially recommend:

• Single-phase transformers 230/230V separating
• Single-phase transformers 230/230V safety cased portable
• Three-phase transformers 400/230V

Each of these types has its own unique applications. Isolation transformers provide galvanic isolation of circuits. This is crucial for safety in many situations. In turn, safety transformers provide protection against electric shock. They are invaluable when working in difficult conditions.

Recently, we advised on the selection of equipment for a large industrial plant project. The client needed a reliable transformer for use in a humid environment. We recommended a model with double insulation and IP54 protection. This solution proved to be perfect, ensuring the safety of employees.

Key parameters when selecting portable transformers

Selecting the right portable transformer requires taking several important factors into account.   In our daily practice, we see how important it is to match equipment to specific needs. Here are the most important aspects to pay attention to:

• Transformer rated power
• Input and output voltage
• IP protection class
• Insulation class
• Weight and dimensions of the device

The rated power determines the maximum load of the transformer. It should be selected with a certain margin. The input and output voltages must correspond to the parameters of the network and devices. The IP protection class is crucial when working in difficult conditions. The insulation class affects the safety of use. The weight and dimensions are important due to the mobility of the equipment.

In the case of office reorganization, we most often recommend lightweight transformers with a power of up to 1kVA. They work great when powering computer equipment. On construction sites, we recommend models with higher power and a durable design. These are often devices with a power of 3-5kVA with a high degree of IP protection.
