The three-phase voltage stabilizer consists of three independent NSN stabilizers assembled and switched in a single housing. The stabilizer is housed in a metal case, allowing it to be used floor-standing. The front panel features LCD indicators displaying (by default) the input and output voltage levels, current, and stage number. The INFINITY 3X series models are designed to stabilize input line voltage in the 200–500 V range and maintain 4.5% output accuracy. These compact devices can be installed horizontally or wall-mounted using a special bracket. Characteristics: Power: 36 kW Output voltage stabilization accuracy: ±%4.5 Number of automatic regulation stages: 16 Operating range of input linear voltages: 200 ÷ 495 V Operating range of output linear voltages: 365 ÷ 397 V Maximum range of input linear voltages: 105 ÷ 520 V Response time to emergency voltage change: up to 20 ms Thermal protection temperature: 105 ° C Dimensions: 310 × 580 × 950 Weight: 105 kg Advantages of this series: • accuracy, speed; • wide range of input voltage; • robust compact design; • long service life; • continuity of control of input current parameters; • effective air cooling of working units; • the ability to adjust the input voltage interval; • reliable protection against overload, overheating and short circuit. The stabilizer provides: • stabilization of the output phase voltage at 220 V, 50 Hz; • automatic disconnection from the network when the input phase voltage increases above the upper limit of the input voltage; • undistorted form of the sinusoidal output voltage; • operation in the entire load range from no-load to maximum load; • protection against short circuits and long-term overload at the output; • transit mode in an emergency; • protection of consumers from overvoltage in transit mode at 265 V (at 445 V linear); • thermal protection of the autotransformer; • disconnection of consumers in case of a short-term disappearance of the power supply network (prevents damage to the pulse power supplies of consumers); • display of the input phase voltage;
