Secure 650VA 455W UPS

Description

The Secure 650VA/455W UPS is designed to provide reliable backup power with an input voltage of 220VAC and operating frequency of 50Hz60Hz. It delivers a stable 220VAC output with a transfer time of 10ms including direction time, ensuring minimal interruption during power fluctuations. The UPS generates a sine wave under main supply and a square wave during battery operation. For safety, it includes overload protection that activates when the load exceeds 130%, cutting off within 3 seconds, along with a fuse for overload and short circuit protection. In the event of a short circuit, the UPS immediately shuts down to protect connected equipment.

Powered by a sealed lead-acid, maintenance-free battery, the system offers auto-inspection, discharge protection, and battery fault caution. Normally, the battery requires charging only once every three months, taking less than 6 hours per cycle. Audible and visual alarms provide clear status indications: when battery capacity is sufficient, a buzzer rings every 4 seconds with a flashing red light; when capacity is insufficient, the buzzer rings every second with the red light flashing; and in the case of low voltage, overload, or short circuit, the buzzer sounds continuously while the red light remains on. This makes the Secure UPS a dependable and efficient choice for safeguarding electronics from power disturbances.
