The PRO-S 5KVA is an automatic servo voltage stabilizer built to safeguard high-demand electrical loads from the damaging effects of unstable mains voltage. Bridging the gap between a small voltage stabilizer and larger mainline units, it suits small workshops, commercial kitchens, telecom equipment rooms, and multi-device office setups. It accepts an input range of 140V – 276V and maintains a steady 230V output with an accuracy of ±1–1.5%, keeping critical equipment running reliably regardless of grid conditions.


Rated at 5KVA with a continuous output current of 20A, this servo voltage stabilizer is engineered for sustained heavy-duty operation — achieving up to 98% efficiency while advanced assembly technology actively limits heat build-up during prolonged use. A front-facing LCD screen delivers real-time visibility of input and output voltage, and the integrated protection system of this automatic voltage stabilizer guards against overvoltage, undervoltage, overload, short circuit, and overtemperature events. A 6-second safe-start delay is activated at every power-on cycle, preventing inrush stress on the connected load.


Compact enough for wall mounting yet robust enough for round-the-clock operation, the PRO-S 5KVA voltage stabilizer regulator holds CE, cULus, and TÜV Austria certifications — a dependable servo voltage stabilizer available across Egypt for residential, commercial, and light-industrial environments where power quality directly impacts productivity.
