Technical Specifications

650VA UPS Capacity

The Power Guard PG650VA-CS provides a 650VA capacity with a maximum load rating of 390W. This makes it suitable for compatible desktop computers, monitors, routers, networking devices, and other electronics that fall within the UPS's rated capacity.

When selecting equipment for connection, calculate the combined power consumption of all devices. The total load should remain below the 390W maximum rating for reliable operation and appropriate backup performance.

Wide Input Voltage Range

The UPS accepts an input voltage range of 145-280VAC. This wide input range helps the UPS accommodate fluctuations in the incoming electrical supply without immediately switching to battery operation.

The built-in voltage regulation function helps provide a more stable output for connected equipment during normal mains operation.

Backup Battery

The PG650VA-CS uses a 12V 7.2Ah maintenance-free lead-acid battery. When mains power fails, the UPS switches to battery operation to keep connected equipment powered for a limited period.

Backup time varies according to the connected load. Published specifications indicate approximately 5-40 minutes depending on load, while some listings specify up to approximately 15 minutes under particular load conditions. Actual runtime will depend on equipment power consumption and battery condition.

AVR and Voltage Protection

The UPS includes Automatic Voltage Regulation (AVR) and high/low voltage protection. These features help protect compatible connected equipment against common mains-voltage fluctuations.

The unit also provides overload and short-circuit protection to help protect the UPS and connected equipment under abnormal electrical conditions.

Offline UPS Operation

The PG650VA-CS is an offline UPS, also known as a standby UPS. Under normal mains conditions, connected equipment operates from the utility supply while the UPS monitors the input. During a power interruption, the UPS switches to battery operation.

The typical transfer time is specified as approximately 2-6ms. Actual transfer behavior depends on operating conditions and connected equipment.

LED Status Indication

The UPS uses an LED display to indicate operating status. Available specifications identify different visual indications for AC operation, battery operation, and overload conditions.

• AC Mode: Green indication
• Battery Mode: Red indication
• Overload: Yellow indication

Plastic Body Design

The Power Guard PG650VA-CS features a plastic body with a compact desktop-oriented design. Its approximately 88.9 × 304.8 × 139.7mm dimensions make it suitable for placement beside or under compatible computer and office equipment.

Applications

• Desktop computers
• Office computers
• Home computers
• Monitors within the rated load
• Wi-Fi routers
• Network equipment
• Modems
• CCTV and networking devices
• Small office electronics
• Other compatible electronic equipment

Compatibility Notice

Do not exceed the 390W load capacity. The 650VA rating does not mean the UPS can continuously power a 650W load. The specified maximum active power capacity is 390W.

For computers with high-power processors or graphics cards, calculate the actual system power consumption before connecting the equipment. The UPS is best suited to loads that remain comfortably within its rated capacity.

Devices requiring a pure sine-wave power source should also be evaluated separately because this model is specified with a modified-sine-wave output.

Why Choose the Power Guard PG650VA-CS?

The Power Guard PG650VA-CS combines a 650VA capacity, 390W load rating, AVR, wide input voltage range, maintenance-free battery, and overload protection in a compact plastic-body UPS.

It is a practical option for users who need short-duration battery backup and voltage protection for computers, networking equipment, and other compatible home or office electronics.
