Phasak Basic Line-Interactive UPS 800 VA / 480 W – Essential protection for IT and network equipment

800 VA / 480 W line-interactive UPS with AVR, designed to protect computers, NAS systems, routers, switches and other sensitive electronic equipment against power outages, micro power cuts, surges and voltage fluctuations. Its compact mini tower format makes it a practical solution for workstations, home networks and small offices.

What is this UPS for?

The Phasak PH 9408 is designed to prevent the most common electrical problems in IT and networking environments:

• Data loss caused by power outages or micro cuts

In the event of an electrical issue, the unit responds immediately to keep connected devices running long enough to save work or perform a safe shutdown.

Main advantages

Automatic Voltage Regulation (AVR)

Compensates for voltage drops and overvoltage without constantly switching to battery mode, helping extend battery life and providing a more stable power supply.

Basic and effective protection

Protects against overvoltage, overload or short circuit, improving the safety of connected equipment.

Compact mini tower format

Its compact design makes installation easier on desks, work areas and locations with limited available space.

Easy to use
