Voltage Stabilizer- PRO-S 30KVA – Single Phase Servo Motor

The PRO-S 30KVA is a heavy-duty automatic servo voltage stabilizer designed for large-scale installations where consistent power quality is critical. Rated at 30KVA with a continuous output current of 120A, it accepts an input range of 140V – 276V and delivers a stable 230V output with an accuracy of ±1–1.5%, protecting high-value equipment from overvoltage, undervoltage, and voltage dips around the clock.

Built for continuous operation, this servo voltage stabilizer runs at up to 98% efficiency with Class H insulation and advanced assembly technology that keeps thermal stress under control across extended duty cycles. A digital LCD display provides real-time visibility of input and output voltage, while the automatic protection system responds instantly to overvoltage, undervoltage, overload, short circuit, and overtemperature conditions. An internal bypass and 6-second safe-start delay ensure supply continuity and a safe power-on sequence at every startup.

The PRO-S 30KVA voltage stabilizer is floor-standing on heavy-duty castors for easy on-site positioning, operates in ambient temperatures up to 50°C, and carries CE, cULus, and TÜV Austria certifications — a proven mainline voltage stabilizer for hospitals, data centres, industrial production lines, and large commercial facilities across Egypt.
