Power Guard 800VA CS Offline UPS

Product Description

Power Guard 800VA CS Offline UPS in Bangladesh

Frequent power cuts can interrupt work, damage sensitive PC components, and cause sudden shutdowns. Power Guard 800VA CS Offline UPS provides dependable battery backup for desktop systems. Its 800VA/480W capacity targets home, office, student, and professional computing setups that need short-duration power protection.

Power Guard 800VA UPS Engineering and Performance

The Power Guard Offline UPS combines a 12V 9.0Ah maintenance-free lead-acid battery with a 480W output rating. Its offline architecture switches connected equipment to battery power during abnormal mains conditions.

The input section accepts 145-280VAC, making the unit suitable for areas experiencing voltage fluctuations. A typical 2-6ms transfer time allows connected computers to transition quickly during a power interruption.

Key electrical characteristics include:

• Capacity: 800VA / 480W
• Input range: 145-280VAC
• Output: 220/230VAC ±10%
• Waveform: Modified-sinewave
• Frequency: 50/60Hz ±5%
• Transfer time: 2-6ms typical
• Battery: 12V 9.0Ah lead-acid
• Battery quantity: 1 piece

Backup Power and Protection Features

The Power Guard UPS provides approximately 5-25 minutes of backup, depending on the connected load. Automatic recharge continues even when the UPS is switched off, while a 6-8 hour charging period reaches approximately 90% capacity.

Protection functions cover several common electrical problems:

• Spike and surge suppression
• Over-voltage and under-voltage battery transfer
• Overload protection
• Short-circuit protection
• Fuse and current limiting
• Intelligent battery management
• Cool-start operation without mains power

The cool-start function can start a connected computer from battery power when utility electricity is unavailable. This is useful during short outages when immediate access to a workstation is necessary.

Practical Indicators and Alarm System

Three status indicators provide quick visual information about operating conditions. Green indicates AC operation, red indicates battery operation, and yellow identifies an overload condition.

A beeping alarm provides an audible warning during relevant UPS events. This combination helps users identify battery operation or excessive load without relying on software monitoring.

Real-World Uses for Computer UPS Bangladesh

The 800VA UPS is best suited to desktop systems with moderate power requirements rather than high-wattage gaming PCs or workstation-class hardware.

Suitable applications include:

• Home desktop computers
• School and college workstations
• Office productivity PCs
• Internet browsing systems
• Small business computers
• POS and administrative terminals
• Entry-level creative workstations

For Bangladesh users, the backup function can be particularly practical during short electricity interruptions. The 480W limit should be checked against the total PC, monitor, and peripheral load before installation.

Compatibility and Setup Guidance

The Power Guard 800VA CS works with equipment that remains within its 480W maximum output capacity. A PC's actual consumption should be considered rather than relying only on the rated wattage of its power supply.

For a practical setup:

• Keep the combined load below 480W.
• Connect only essential peripherals.
• Place the UPS on a stable, ventilated surface.
• Avoid plugging high-power appliances into the UPS.
• Allow adequate charging time after extended discharge.

The modified-sinewave output is suitable for many conventional desktop applications, but users operating equipment with strict waveform requirements should verify compatibility before purchase.

Bangladesh Climate and UPS Maintenance Tips

Bangladesh's warm, humid, and dusty environment makes ventilation and regular cleaning important for UPS reliability. The specified operating range is -5°C to 45°C, with humidity tolerance from 20% to 90%.

Practical maintenance includes:

• Keep ventilation areas free from dust.
• Avoid placing the UPS beside heat-producing equipment.
• Keep the unit away from moisture and direct water exposure.
• Inspect cables and plugs periodically.
• Allow proper charging after deep battery discharge.

The maintenance-free lead-acid battery reduces routine battery servicing, while intelligent battery management supports controlled battery operation.

Power Guard 800VA CS Warranty and PCB Store Support

The Power Guard UPS comes with 01 year battery warranty and 01 year service with spare parts. Warranty terms provide coverage for the specified period, subject to applicable retailer and manufacturer conditions.

PCB Store Bangladesh provides product support for warranty processing and technical concerns. Genuine Original Power Guard Products should be verified through the retailer before purchase, particularly when comparing offers across the local market.

UPS Price in BD and Purchase Guidance

The UPS Price in BD depends on current stock and retail pricing. Buyers should compare the rated 800VA/480W capacity, battery specification, warranty coverage, and protection features rather than selecting solely by price.

The Power Guard 800VA CS is a practical Backup Power Supply for moderate desktop loads requiring short-duration protection. Buy Power Guard UPS Bangladesh from PCB Store for genuine product availability, local warranty assistance, and nationwide delivery support.

Power Guard 800VA CS Overall Verdict

The Power Guard Offline UPS is a sensible choice for users needing basic battery backup, voltage protection, and automatic charging in a compact plastic chassis. Its 480W ceiling makes load calculation essential.

Its strongest advantages include a broad 145-280VAC input range, 5-25 minute load-dependent backup, surge protection, cool-start capability, and intelligent battery management. The modified-sinewave output remains an important consideration for specialized equipment.
