Three phase AVR voltage stabiliser 30kVA LCD
Three phase AVR voltage stabiliser 30kVA LCD
Guarantee: 24 mth
Description: A stable power supply for professional equipmentThe stabiliser utilises SERVO control technology, in which a servo motor controls the position of the voltage regulators moving arm. This solution allows the unit to respond automatically to changes in mains parameters and smoothly adjust the input voltage without the need for manual operation, ensuring a stabilised output voltage of 380 V.Precise output voltage stabilisation 3%The stabiliser maintains the rated output voltage at 380 V AC with an accuracy of 3%. This means that during normal operation, the output voltage is stabilised within a range of approximately 368.6391.4 V AC. The measurement system continuously monitors the power supply parameters, whilst the servo motor control automatically corrects any deviations in the input voltage. This helps to minimise the impact of mains fluctuations on connected machinery, industrial equipment and other three-phase loads.Monitoring of every stage for greater system safetyModels with a power rating of 15 to 40 kVA are equipped with a 6-transformer system, comprising 3 Variac regulating autotransformers and 3 compensation transformers. Each phase has its own separate control unit, which allows independent correction of the L1, L2 and L3 voltages. The Variac autotransformers work in conjunction with a servo mechanism to adjust the regulation level, whilst the compensation transformers increase or decrease the voltage in accordance with the current mains parameters. This solution ensures smooth stabilisation, an output voltage accuracy of 3 per cent and reliable operation of the connected equipment. A multi-level protection system for three-phase installationsThe comprehensive Multi-Protection system helps to minimise the risk of damage to machinery, industrial equipment and other three-phase loads, ensuring greater reliability and continuity of operation for the installation.The stabiliser provides protection against: reversal of the phase and neutral wires, loss of one of the phases, incorrect phase sequence, loss of the neutral wire, excessive voltage surges. Stable voltage for heat pumps, compressors and advanced control electronicsWith models available in power ratings from 10 to 40 kVA, the voltage stabiliser can be selected to meet the requirements of a specific installation and used, amongst other things, to power: three-phase heat pumps, compressors, motors and pumps, production machinery and machine tools, industrial automation systems, refrigeration and air-conditioning equipment, servers, ICT cabinets and network infrastructure, heating systems and technical installations, office equipment and professional electronic equipment. The key parameters are always clearly visible on the easy-to-read LCD screenThe built-in LCD display allows real-time monitoring of the stabilisers operating parameters for each of the three phases. The screen displays the voltage and current values for phases L1, L2 and L3, allowing the user to quickly assess the power supply status and detect any anomalies. Clear messages make it easier to identify the cause of a fault and take appropriate action.The panel also indicates key operating statuses and warnings, such as: voltage too low or too high, overload, overheating, phase loss, active start-up delay.
