2 KVA Isolation Transformer – Single Phase

2 KVA Isolation Transformer

The Purevolt 2 KVA isolation transformer is a single-phase 230 V AC input and 230 V AC output unit developed for medium electronic loads that require electrical separation from the incoming mains. It can be used with control systems, laboratory equipment, communication devices, office electronics, medical instruments, test systems, and grouped loads whose total demand is within the transformer’s rated capacity.

The transformer transfers energy magnetically between separate primary and secondary windings. This breaks the direct conductive path between the supply and the connected load, providing galvanic isolation. In a correctly engineered installation, this arrangement can improve supply separation and help attenuate common-mode noise that may affect sensitive electronics.

Suitable Applications for a 2 KVA Isolation Transformer

The 2 KVA rating offers more capacity than a 1 KVA model while remaining compact enough for localized equipment protection. It is commonly considered for:

• Small industrial control panels
• PLC, HMI, and instrumentation systems
• Laboratory analysers and measuring equipment
• Communication and telecom systems
• Medical and diagnostic electronics
• Computer workstations and peripheral equipment
• Audio-video production systems
• Printing and packaging-machine control electronics
• Security and access-control systems
• Equipment servicing and test benches
• Research and educational laboratories
• Multiple low-power devices on one isolated supply

Application suitability depends on current, power factor, inrush, duty cycle, and installation conditions. Equipment with motors, compressors, heaters, large transformers, or high-capacitance power supplies may require a larger rating even when normal running power appears modest.

Technical Configuration

• Capacity: 2 KVA
• Phase: Single phase
• Nominal input: 230 V AC
• Nominal output: 230 V AC
• Function: Input-output electrical isolation
• Cooling: Air cooled
• Construction: Enclosed transformer assembly
• Application: Sensitive electrical and electronic loads

Additional requirements such as an electrostatic shield, input-output protection, special cable terminals, wheels, meters, non-standard voltages, or a specific enclosure should be stated before manufacture or dispatch.

Why Use a 2 KVA Isolation Transformer?

Sensitive equipment can be affected by unwanted electrical references, common-mode interference, and disturbances conducted through the mains connection. Separate windings create an isolated secondary circuit and can reduce the direct transfer path for certain types of interference. This can support more reliable operation of measurement, communication, control, and audio equipment.

Isolation should not be confused with voltage regulation. If the incoming voltage varies significantly, the output of a 1:1 transformer will generally vary in relation to it. A servo voltage stabilizer or automatic voltage regulator may therefore be required in addition to the isolation transformer. Similarly, surge protection, circuit breakers, residual-current protection, earthing, and an online UPS each address different electrical risks.

Load Calculation and Current Capacity

At 230 V, a 2 KVA rating represents approximately 8.7 A under ideal unity-power-factor conditions. This is a theoretical reference, not a universal loading recommendation. Transformer losses, power factor, harmonics, inrush current, ambient temperature, ventilation, and continuous-duty requirements must be considered.

List the rated VA, watts, current, and startup demand of all connected equipment. Where several devices operate together, add their simultaneous demand and include suitable spare capacity. For electronic loads with switch-mode power supplies, ask the equipment supplier or Purevolt team about inrush and harmonic considerations.

Place the transformer in a clean, dry, ventilated area with sufficient space for heat dissipation and inspection. Use appropriately rated cables, lugs, isolators, breakers, and terminals. Protect the unit from rain, water leakage, corrosive chemicals, excessive dust, impact, and obstruction of ventilation openings.

The secondary earthing arrangement must be chosen for the intended application and applicable electrical rules. Do not assume that an isolated output can be installed without protective earthing or fault protection. Commissioning should be carried out by a qualified electrician who can verify input-output voltage, insulation, earth continuity, load current, temperature, and protective-device operation.

Maintenance

Routine checks should include terminal tightness, cable condition, ventilation, dust accumulation, unusual sound, overheating, insulation condition, and load current. Disconnect and isolate the supply before inspection. Persistent humming, smells, abnormal heat, tripping, or voltage drops should be investigated rather than ignored.

2 KVA Isolation Transformer Price

The price of a 2 KVA single-phase isolation transformer varies with winding material and design, insulation, shielding, enclosure, terminals, protection devices, taxes, freight, and customization. The product page displays the standard listed model and price, while special configurations require a separate quotation.
