8?Outlet Standby UPS:

The CyberPower ST425 Standby UPS is an affordable, compact uninterruptible power supply ideal for protecting home offices, workstations, entertainment systems, and network gear from unexpected outages and power surges. With a capacity of 425?VA / 260?W and 8 outlets?4 offering battery backup and surge protection, and 4 offering surge protection only?it gives you flexible protection for multiple devices. Featuring ENERGY STAR certification and CyberPower?s efficient GreenPower UPS? design, it minimizes energy waste while maintaining readiness.

Features

The ST425 utilizes standby (offline) topology with simulated sine wave output, offering a cost-effective UPS solution for non-critical IT equipment. When normal AC utility power is present, your devices run directly from the grid; upon power disruption, the unit switches to battery mode in about 8?ms?enough time to sustain computers, routers, and consoles, giving you time to save work or trigger automatic shutdowns.

Advanced Options

It includes 890?J surge suppression, EMI/RFI noise filtering, and transformer-spaced outlets to accommodate large adapters without blocking other plugs. The GreenPower UPS? design reduces power consumption, lowering heat and operating costs?while ENERGY STAR certification reinforces its efficiency credentials. Auditory alarms and LED indicators inform you of battery mode, low battery, overload, or fault conditions.
