Online Power Frequency Machine UPS Three In Single Out

Online power frequency machine UPS three in single out is a three-input single-output online power frequency UPS power supply, which is an uninterruptible power supply device that converts three-phase AC input into single-phase AC output. When the mains power is normal, the mains power is rectified into DC power, and then converted into stable single-phase AC power output to the load through the inverter. When the mains power is abnormal, the battery supplies power to the inverter to continue to provide uninterrupted power support for the load.

Working principle: It is mainly composed of rectifier, inverter, battery, control circuit, etc. The rectifier converts the input three-phase AC power into DC power, one part of which is used to charge the battery and the other part is supplied to the inverter; the inverter converts DC power into stable single-phase AC power output to the load; the battery provides DC power to the inverter when the mains power is interrupted; the control circuit is responsible for monitoring and controlling the operating status of the entire system to ensure the stability of the output voltage and frequency.

Online power frequency machine UPS three in single out advantages:

1. High output stability: It can provide stable single-phase output voltage and frequency, effectively protect sensitive equipment from power fluctuations, surges and other power quality problems, such as ensuring the stable operation of computers, servers and other equipment.

2. No switching time: The load is always powered by the inverter, and there is no delay or switching time when the mains power is off, which can achieve seamless power supply to the load and ensure the continuous operation of key equipment. It is suitable for places with extremely high requirements for power supply continuity, such as financial data centers, hospital operating rooms, etc.

3. Good electrical isolation: The power frequency machine is based on the transformer design, which enables good electrical isolation between input and output, can reduce the impact of electrical noise and interference on the mains side on the load, and improve the reliability and stability of the equipment.

4. Large input capacity: With three-phase input, the large capacity characteristics of the three-phase power supply can be used to provide higher power support for single-phase loads, meeting the power needs of some large or high-power single-phase equipment, such as single-phase control circuits in large industrial automation equipment.

Product technical parameters

Input voltage range: The voltage of the Online power frequency machine UPS three in single out is generally 340V-460V The wider input voltage range can adapt to different mains power environments, reduce the number of times the UPS switches to battery power due to mains voltage fluctuations, and extend battery life.

Output voltage: usually 220V or 230V, etc., which can be adjusted according to different load requirements. The accuracy of the output voltage is generally between±1% -±2%, which can provide stable voltage support for the load.

Output frequency: mostly 50Hz or 60Hz, the accuracy of the output frequency can reach about±0.01% -±0.5%, ensuring synchronization with the mains frequency and meeting the frequency stability requirements of most loads.

Power capacity: The power range is wide, with common specifications such as 10KVA-30KVA. You can choose the appropriate UPS model according to the actual load power requirements to ensure that sufficient power support can be provided for the load when the city power is interrupted.

Product application scenarios

Industrial field: In industrial production, the control systems or auxiliary equipment of many large equipment may be single-phase loads, but the power supply of the factory is usually three-phase power supply. The three-input single-output UPS can provide stable backup power for such equipment to ensure the continuity and stability of the production process, such as controllers, sensors, displays and other equipment in industrial automation production lines.

Commercial places: In places such as shopping malls, supermarkets, office buildings, etc., there are a large number of single-phase office equipment, commercial lighting equipment and cash register systems. The three-input single-output UPS can provide reliable power guarantee for these key equipment to prevent business interruption and data loss due to mains failure.

Medical industry: Some important medical equipment in hospitals, such as CT machines, X-ray machines, monitors, etc., are partly single-phase equipment and have extremely high requirements for power supply quality and continuity. The three-input single-output UPS can ensure that these equipment can still operate normally when the mains power is abnormal, providing guarantee for the diagnosis and treatment of patients.

Communication base station: Some communication equipment in the communication base station is single-phase load, and the three-input single-output UPS can provide it with a stable power supply to ensure the normal operation of the communication network and avoid communication interruption due to power outages.
