Online Power Frequency Machine UPS Single In Single Out

Online power frequency machine UPS single in single out Product overview

1. Single input Single Output (SISO) Uninterruptible power supply (UPS) is a power backup device.

2. Online: In the online UPS, the load is always powered by the inverter. The inverter continuously converts direct current (from the rectified AC input or battery) into an AC supply load. This provides a high degree of protection against power outages and power quality issues, as there is no switching time when the mains is off.

3. Power frequency machine: This refers to the type of inverter used. Power frequency inverters usually operate at the mains frequency (50Hz or 60Hz). They typically have a transformer-based design that provides good isolation and stability.

4. Single input single output: This means that the UPS has a single phase input (getting power from a single phase AC power supply) and a single phase output (providing power to a single phase load). This type of UPS is suitable for small and medium-sized loads, such as personal computers, small servers, and some office equipment.

Online power frequency machine UPS single in single out components and working principles

1. Rectifier: converts the input mains AC to direct current. This direct current is used to charge the battery and provide power to the inverter.

2. Battery: Store electrical energy. When the mains power goes out, the battery provides the inverter with the direct current it needs to continue powering the load.

3. Inverter: Converts direct current (from a rectifier or battery) into alternating current with stable voltage and frequency. The output of the inverter is connected to the load.

4. Transfer switch: in some Online power frequency machine UPS single in single out design (although the online UPS is not so critical for power conversion), used to switch between the mains power supply and the inverter output. In an online UPS, the transfer switch is usually in a position that always allows the inverter output to power the load.

Control circuit: Monitor input power quality, battery status and load. It controls the operation of rectifiers, inverters and transfer switches to ensure a stable and uninterrupted power supply to the load.

Online power frequency machine UPS single in single out advantage

1. Power quality: Provides very stable output voltage and frequency to protect sensitive equipment from power fluctuations, surges, voltage drops and other power quality problems.

2. No switching time: Since the load is always powered by the inverter, there is no delay or switching time when the mains is cut off, ensuring seamless power supply to the load.

3. Isolation: The transformer based design of the power frequency machine can provide good electrical isolation between the input and output, protecting the load from electrical noise and interference on the mains side.

Online power frequency machine UPS single in single out shortcoming

1. Efficiency: In general, due to the use of transformers and the continuous operation of the inverter, the efficiency of the power frequency UPS is lower than that of the high-frequency UPS.

2. Size and weight: Transformer-based designs make UPS larger and heavier than high-frequency designs.

3. Cost: Due to the use of more components such as transformers, the cost of power frequency UPS is usually higher.

Online power frequency machine UPS single in single out application scenario

1. Office environment: suitable for supplying power to office computers, printers and other small and medium-sized office equipment.

2. Small and medium-sized servers: can be used to provide backup power for small and medium-sized servers in small businesses or branches.
