20KVA Automatic Servo Voltage Stabilizer – Single Phase | PRO-S

The PRO-S 20KVA is a 20 kva single phase automatic voltage stabilizer built to protect large electrical installations from the damaging effects of mains voltage fluctuations. Whether you need a mainline voltage stabilizer for home or a heavy-duty servo voltage stabilizer for industrial use, the PRO-S range delivers. It accepts a wide input range of 140V – 276V and regulates the output to a stable 230V with an accuracy of ±1–1.5%, ensuring all connected equipment receives a consistent and clean power supply at all times.

Rated at 20KVA with a continuous output current of 80A, this automatic servo voltage stabilizer operates at an efficiency of up to 98% with Class H insulation and advanced assembly technology that minimises heat losses during extended operation. A smart digital LCD display provides real-time monitoring of input and output voltage, while the built-in protection system automatically responds to overvoltage, undervoltage, overload, short circuit, and overtemperature conditions. An internal bypass and 6-second safe-start delay ensure supply continuity and a controlled power-on sequence for the connected load.

Suitable for large commercial buildings, industrial workshops, centralised HVAC systems, and heavy medical equipment setups, the PRO-S 20KVA voltage stabilizer regulator is floor-standing on heavy-duty castors for flexible positioning and easy relocation. From a 1kva automatic voltage stabilizer for small loads to a 20KVA servo voltage stabilizer for demanding applications, the PRO-S series covers every requirement. It operates reliably in ambient temperatures up to 50°C and carries CE, cULus, and TÜV Austria certifications — a dependable voltage stabilizer available across Egypt for demanding single-phase applications.
