Explanation of power supply terms related to UPS power supply

UPS power generally refers to uninterruptible power supply. UPS (Uninterruptible Power Supply) is an uninterruptible power supply with an energy storage device. Many people do not know much about some accessories and power terms of online UPS power supply. Now let Upsystem Power factory explain the power terms related to UPS power supply in detail for you.

Power factor: For a device, there are two different parameters: input power factor and output power factor. The absolute value of power factor is between 0 and 1. It is between W (active power) and VA (apparent power). ratio. The higher the input power factor, the higher the utilization efficiency of the UPS to the grid, and the power factor of the energy-saving UPS is above 0.9. Considering the output end, the higher the output power factor, the stronger the UPS's load capacity, and the lower the output power factor, the weaker the UPS's load capacity.

Power factor correction: a means to improve the input power factor of electronic equipment. After the UPS is equipped with a power factor correction circuit, its input power factor can be greatly improved.

National standard socket: China's standard socket form, the zero and live wires are arranged in / font, and the ground wire is at the head of.

American standard socket: the standard socket form of the United States, the zero and live wires are arranged in 11-shape, and the ground wire is at the head of 11.

Common mode: refers to a way of the noise flow path. Any noise that comes from the power hot wire (HOT) or neutral wire (NEUTRAL) and returns through the ground wire is called common mode noise.

Silicon barrier diode: It is a diode designed with silicon (AILICON) as the main raw material. The difference between silicon barrier diode and general diode is that when the voltage exceeds its designed rated voltage, the two The polar body produces a barrier effect (AVALANCHEEFFECT) and turns on, so the silicon barrier diode is often used as a voltage regulator diode.

Fault current: refers to the flow of abnormal current in the line.

"Three remotes": remote signaling, telemetry, and remote control. Refers to remote monitoring of equipment.

Isolation: The power grid uses live wire and neutral wire to transmit power. Therefore, external lightning strikes will damage the internal electronic components of the appliance through the live wire and neutral wire. Therefore, many UPS or electrical equipment are equipped with transformers at the output and input terminals to connect the equipment to the electrical equipment. The grid is electrically isolated to solve the above problems and reduce noise.

High-frequency machine: Using high-frequency switching technology, the UPS that replaces the bulky power frequency transformers in the rectifier and inverter with high-frequency switching elements is commonly known as a high-frequency machine. The high-frequency machine is small in size and high in efficiency.

Power frequency machine: UPS using power frequency transformer as rectifier and inverter components is commonly known as power frequency machine. The main features are that the main power components are stable, reliable, overload capacity and shock resistance.

Management information base: a software module used to support SNMP network equipment, which stores the status information of the network equipment for the network management system or users to inquire about the equipment status.

Interactive: A working mode of UPS, the basic structure consists of bidirectional inverter, battery and switch. When the grid fails, the inverter supplies power to the load, and when the grid is normal, the inverter turns to charge the battery. The interactive UPS has a strong charging function, but there is a switching time for the output.

Backup type: A working method of UPS, the basic structure consists of an inverter, a battery pack and a switch. When the grid is normal, the inverter stops outputting AC power, and the AC power from the grid supplies power to the load through the UPS. When the power grid fails (power failure, undervoltage, overvoltage, etc.), the UPS switches to the inverter output mode through the switch. This conversion process has a switching time of 3-10ms.
