The Power Guard PG650VA-CS is a dependable 650VA offline UPS designed to protect essential electronics during power interruptions and unstable mains conditions. With a rated output capacity of 390W, it is well-suited for home and small office setups where you need dependable runtime for devices such as monitors and other connected equipment. Its simulated sinewave output and fast transfer capability help keep your workflow stable when the power goes out.
This UPS supports an input voltage range of 145–280V, helping it operate across a wide range of common voltage fluctuations. The unit runs on 50/60Hz input frequency (±5%), and it delivers an output voltage of 220/230VAC with a tolerance of ±10%. For switching behavior, the transfer rate is typically 2–6ms, which is important for reducing disruption to connected equipment during outages.
Powered by a 12V 7.2Ah battery, the PG650VA-CS provides backup time of 10–15 minutes at full load for a typical pairing such as 1 UPS unit and 1 monitor. After power returns, the UPS supports automatic recharge even when the UPS is off, which helps ensure the battery is ready for the next interruption. The recharge time is 6 hours up to 90% capacity, making it convenient for daily use in environments where outages may be frequent.
Built for safer operation, the UPS includes automatic voltage regulation (AVR) along with high/low voltage protection. It also provides overload and short protection to help safeguard the connected load. Additional convenience features include an LED display for quick status checks, a beeping alarm for alerts, and intelligent battery management to support consistent performance over time. The UPS also supports cool start operation for a computer even when there is no main power, which can be especially helpful during sudden outages.
The Power Guard PG650VA-CS is compatible with generators, making it a practical choice for backup power systems where you may rely on generator output during extended outages. It features two output connections on the back side, allowing you to connect typical office or home essentials. The plastic body supports a compact, lightweight installation, and the included cable length of 0.86 meters supports straightforward placement near your equipment.
As an offline UPS with simulated sinewave output, this model is best for common electronic loads such as monitors and typical office equipment that can operate reliably with this waveform type. If your setup includes sensitive equipment, it’s a good idea to confirm compatibility with simulated sinewave UPS power. For many everyday home and office use cases, the combination of AVR, fast transfer, and protective circuitry makes this UPS a practical and cost-conscious power backup solution.
The UPS comes with a 1-year warranty, including 1 year battery & service. For warranty claims, the box is mandatory. The unit is made in China and weighs 4.6 Kg, with dimensions of 88.9 x 304.8 x 139.7 mm.
