UPS Phasak 2000VA LCD USB with protection for RJ45

Phasak PH-9420 2000VA Interactive UPS with AVR

The Phasak PH-9420 is a 2000VA (1200W) line-interactive UPS designed to protect computers, servers, NAS systems and network equipment against power outages, voltage drops, surges and electrical noise. Its built-in Automatic Voltage Regulation (AVR) stabilises the output voltage without continuously using the battery, helping to extend battery lifespan.

This UPS is ideal for office environments, home networks and small business applications where reliable power protection and system stability are essential. The integrated LCD display allows real-time monitoring of operating status, load level and battery condition.
