Three Phase Servo Voltage Stabilizer - PRO-S | 3KVA

The PRO-S 3KVA is a compact three-phase servo voltage stabilizer designed for installations that require balanced, reliable power across all three phases. Built around a precision servo motor stabilizer mechanism, it accepts a three-phase input range of 280V – 480V and delivers a stable 3 × 400 Vac output with an accuracy of ±1–1.5%, with independent phase monitoring ensuring consistent protection across every phase at all times.

Engineered for continuous duty, this automatic servo voltage stabilizer runs at up to 98% efficiency with Class H insulation and natural air cooling that keeps thermal stress under control across extended operating cycles. Harmonic current is held to ≤5% at ohmic load, and this electrical stabilizer performs reliably in ambient temperatures up to 50°C.
Compact and floor-standing at 380 × 265 × 605 mm with a weight starting from 21kg, the PRO-S 3KVA servo stabilizer is straightforward to install and easy to position on site. With an IP23 indoor protection rating, a 3.5KV test voltage, and Class H insulation, it is a dependable three-phase servo voltage stabilizer available across Egypt for any installation where three-phase power quality matters.
