Single & Three Phase Variable Voltage Transformer – 1 KVA to 1000 KVA

This variable voltage transformer is designed for precision control of AC voltage in both single-phase (230V) and three-phase (415V) systems. Output voltage is manually adjustable from 0 to 230V (single-phase) or 0 to 415V (three-phase), allowing flexible operation for test benches, control equipment, and regulated supply systems.

The transformer is available in dry type or oil-immersed construction, with power capacity ranging from 1 KVA to 1000 KVA (1 MVA), offering excellent scalability for industrial and laboratory use. Built to operate in ambient temperatures up to 50°C, it supports Class F or Class H insulation for reliable thermal performance.

For user protection and environmental adaptability, it can be configured in IP00 (open frame), IP23 (drip-proof), or IP65 (dust-tight, water-jet proof) enclosures. Output control can be achieved using a manual knob or an optional push-button interface for enhanced operator precision.
