Single-phase voltage stabilizer RETA НОНС-35 kW CALMER SEMIKRON Without circuit breaker 3-17

CALMER Stabilizers — this is the flagship line of single-phase voltage stabilizers from the Ukrainian manufacturer TM “Reta”. Models in this series are designed specifically for mission-critical equipment that requires the most precise and uninterrupted power supply. Thanks to its high technical specifications, CALMER is ideal for cottages, homes, as well as industrial enterprises and facilities with increased requirements for power quality.

Key advantages of the CALMER series

• Highest stabilization accuracy in the lineup — 36 adjustment levels with a step of ±3 V (±1%) ensure a stable 220 V voltage even during significant fluctuations in the grid.
• The ideal solution for critical equipment — welding machines, compressors, MRI, CT, X-ray units, server and telecommunications systems.
• Wide input voltage range — models in the series cover values from 130 to 289 V with automatic shutdown at 260–314 V.
• Works with generators — maintains stable operation even with gasoline/diesel generator sets.
• Low power consumption — only 10–20 W in standby mode with up to 98% efficiency.
• Fast response — reacts to voltage changes in 20 ms, preventing even brief interruptions.
• Intelligent protection — against overload, overheating, short circuit, and input/output overvoltage.
• Does not distort the sine wave — an important feature for electronics and medical equipment.
• Compatibility with SES — capable of operating in renewable energy systems, supports the “green tariff.”
• Reliable construction — steel housing, IP20 protection rating, fan cooling.
• Manufactured in Ukraine — local production, adapted to our power grid conditions.

Intelligent control and monitoring

• Microprocessor control — ensures uninterrupted operation and automatic adaptation to changes in the grid.
• Advanced user menu — full control over parameters, statuses, and operating modes.
• Web interface (optional) — monitoring and control of the stabilizer via smartphone or computer (iOS/Android).
