UPS power supply, also known as a lead-acid battery, operates on the same principle as open-vent lead-acid batteries, even though the same battery technology is used in UPS power supplies. Battery life varies significantly between manufacturers, which is crucial for users. Battery temperature affects the reliability of the batteries in the RediStar UPS system under normal operating conditions. The temperature also has a significant impact on the natural aging process of the batteries during energy conversion. This is also a key reason why the replacement cycle for backup or online interactive UPS batteries is relatively long.

后备式UPS (Offline UPS)
During normal mains power, the equipment is powered directly by the utility power. In the event of a power outage, the battery inverter supplies power.
Its features include: simple structure, compact size, low cost; however, it has a narrow input voltage range, switching time, and is not suitable for equipment with high power quality requirements. It is commonly used in personal computers.
Interactive Online UPS
When AC power is normal, the inverter operates by receiving DC power from the rectifier. It directly supplies AC power to the equipment. Meanwhile, the charger charges the battery, maintaining full capacity. The inverter is always in operation, ensuring continuous output without any switching time. Suitable for equipment with high power quality requirements.
Features:
Simple structure, compact size, low cost; however, narrow input voltage range, poor output voltage stability, with switching time, and the output waveform is typically square wave. Therefore, backup UPS systems are not suitable for equipment with high power quality requirements and are generally used in personal computer systems.
Service Method: 7*24 service, same-day shipment, no charge for installation on-site!
