What are the important technical parameters and specifications of UPS uninterruptible battery power supply?

Important technical parameters and specifications of UPS uninterruptible battery power supply 1. The UPS host requires single-in and single-out, double conversion pure on-line, power 3KVA, and requires a standard output isolation transformer, with a backup time of 3 hours. 2. UPS rectification requires SCR phase control technology or IGBT rectification technology. 3. Input voltage range: mains input voltage is 220V±25%. 4. Require the invested UPS manufacturers to obtain my country's Green Star certification. 5. Rectifier input frequency range: 40～70Hz. 6. Output voltage range: L-N: 220V±1%; mains power is normal, automatic synchronization tracking; mains power failure, this machine 50±0.2%. UPS uninterruptible power supply products on the market generally have capacity specifications of 0.5, 0.65, 1, 2, 3, 4, 5, 6, 8, 10, 15, 20, 30, 40, 60, 80, 100, 120, 160, 200, 300, 400, 500, 600, 800, 1000KVA, etc., and have formed a series of products. The important technical parameters of UPS include: rated capacity, input voltage range, input power factor, output voltage, output power factor, battery voltage, overall efficiency, etc. UPS is divided into two specifications: centralized and decentralized. The advantages and disadvantages of these two specifications are as follows: 1. The centralized power supply mode is easy to manage and the wiring requires high reliability and low cost. 2. Distributed power supply mode is inconvenient to manage wiring requirements, low reliability, high cost, and low cost.
