1 kVA 3 Phase Transformer Price

In the realm of electrical systems, transformers play a vital role in ensuring safe and efficient power distribution. One of the smallest yet significant units is the 1 kVA 3 phase transformer. Despite its compact guide power capacity, it holds a unique position in specialized applications such as instrumentation, automation, and control panels. This article explores everything from pricing to technical comparisons, market background, and expert selection advice.

What Is a 1 kVA 3 Phase Transformer?

A 1 kVA (kilovolt-ampere) 3 phase transformer is a low-capacity electrical transformer designed to convert three-phase voltage levels while delivering a total apparent power of 1,000 VA (or 1 kVA). It is typically used to:

• Step down a higher voltage (e.g., 400V) to a usable lower voltage (e.g., 208V, 240V, or 120V);
• Isolate circuits for safety;
• Match impedance in sensitive control equipment.

These transformers are often dry-type or encapsulated, and constructed with laminated silicon steel cores to reduce eddy current losses.

Applications of 1 kVA 3 Phase Transformers

Despite its low capacity, a 1 kVA transformer finds relevance in:

• Automation Systems: PLCs and sensor control circuits;
• Laboratory Equipment: Powering small three-phase instruments;
• Marine and Aerospace: Where space and weight limitations matter;
• UPS and Power Conditioning: For signal stability in control loads;
• Medical Devices: For circuit isolation and voltage adjustment in low-power devices.

Its compact size, low heat emission, and ease of installation make it ideal for indoor panels, control cabinets, and limited-space installations.

Market Pricing Overview

The price of a 1 kVA 3 phase transformer varies depending on several factors including:

• Manufacturer (e.g., ABB, Schneider Electric, Siemens, local OEMs);
• Input/output voltage configurations;
• Core material (CRGO steel, amorphous metal);
• Type (dry-type, oil-filled, resin-encapsulated);
• Regulatory compliance (UL, CE, IEC 60076 standards).

Typical Price Range

Note: Prices may vary by country, shipping, taxes, and supplier markup.

Differences from Other Transformer Types

In summary, 1 kVA 3 phase transformers are more expensive per kVA, but they provide precision and stability where it’s needed.

Buying Advice and Selection Tips

Here are expert tips to help you choose the best 1 kVA 3 phase transformer:

1. Match Input/Output Voltage Requirements
   Common configs: 480V to 240V, 400V to 208V, etc.
2. Choose the Right Core Type
   Toroidal = higher efficiency and lower noise, but higher cost.
3. Check Certifications
   For industrial or export use, UL, CE, or IEC compliance is essential.
4. Consider Environmental Conditions
   For dusty or moist areas, use epoxy-coated or encapsulated types (IP44+).
5. Compare Total Cost of Ownership
   An efficient transformer saves energy and reduces panel heat—ideal for long-term use.
6. Buy from Trusted Brands
   ABB, Schneider Electric, Eaton, and Siemens are known for reliability and global support.
