4 KVA Isolation Transformer – Single Phase

The 4 KVA isolation transformer from PowerRed Transformers is intended for electrical and electronic applications that require an isolated power supply with a higher rated capacity than smaller transformer models. It can be considered for compatible industrial control systems, testing facilities, laboratory instruments and multiple electronic devices operating within the transformer's specified rating.

A single-phase isolation transformer transfers electrical energy through magnetic induction between separate primary and secondary windings. This provides galvanic isolation between the input and output circuits. Depending on the design, shielding and installation, it may also help reduce the transfer of certain types of common-mode electrical interference.

Key Features of a 4 KVA Isolation Transformer

• 4 KVA rated capacity: For compatible equipment loads within the specified operating limits.

• Single-phase operation: Designed for applications requiring a single-phase isolated supply.

• Galvanic isolation: Separate primary and secondary windings provide electrical separation.

• Industrial and commercial applications: Suitable for selected control, testing, laboratory and electronic equipment.

• Configurable specifications: Input voltage, output voltage, cooling method and enclosure should be selected according to the application.

Applications of a 4 KVA Isolation Transformer

A 4 KVA single-phase isolation transformer may be suitable for industrial automation panels, laboratory and testing equipment, electronic measuring instruments, IT and communication systems, printing and packaging machine controls, and other compatible electrical loads.

Its suitability depends on the combined load, power factor, startup current, operating duty and installation environment. Equipment with motors or high inrush currents may require additional capacity assessment.

How to Select a 4 KVA Isolation Transformer

Before ordering, confirm the required input and output voltage, frequency, total connected load, operating current, installation conditions and any additional shielding or protection requirements. The transformer should be selected using the equipment manufacturer's specifications rather than KVA rating alone.

An isolation transformer primarily provides electrical isolation; it does not independently correct sustained high or low input voltage. A servo voltage stabilizer, UPS or other power-conditioning equipment may be required if the application also needs voltage regulation or backup power.
