The PRO-S 1KVA is a 1kva automatic voltage stabilizer engineered to deliver reliable protection for sensitive electrical equipment against mains voltage fluctuations. As a compact servo voltage stabilizer, it is ideal for powering home appliances, office equipment, and medical devices — making it one of the most practical small voltage stabilizers for everyday use. It accepts a wide input range of 140V – 276V and regulates the output to a stable 230V with a tight accuracy of ±1.5%.
Built for demanding environments, this automatic servo voltage stabilizer achieves an efficiency of up to 98% while keeping heat losses minimal through advanced assembly technology. It operates at ambient temperatures up to 50°C and features a real-time LCD display showing live input and output voltage values. The comprehensive protection suite of this voltage stabilizer regulator covers overvoltage, undervoltage, overload, short circuit, and overtemperature conditions — complemented by a 6-second safe-start delay that shields the connected load at power-on.
Compact, lightweight, and straightforward to install, the PRO-S 1KVA voltage stabilizer carries international approvals including CE, cULus, and TÜV Austria — a trusted automatic voltage stabilizer available across Egypt for residential, commercial, and light-industrial applications.
