Mecer ME-1000-VU 1000VA/600W Line-Interactive UPS

South Africa’s Most Common Home UPS

The Mecer ME-1000-VU is one of the most widely deployed UPS units in South African homes and small offices. Designed and supported locally by Mustek (South Africa’s largest IT assembler and distributor), it combines reliable performance with a price point that makes sense for everyday load shedding protection.

It provides 600W of usable backup power — enough to run a desktop computer, monitor, Wi-Fi router, and a network switch simultaneously, keeping your home office or entertainment setup online through Stage 2 and Stage 3 load shedding without interruption.

AVR — Protection Beyond Just Backup

The automatic voltage regulation (AVR) function corrects brownouts and overvoltages without switching to battery power. South African grid voltage frequently sags or spikes during peak demand periods. The AVR function keeps your equipment supplied with stable voltage even when the grid is present but unstable — extending the life of sensitive electronics.

What Can You Power?

At 600W real power output, the ME-1000-VU can support:

• Desktop PC (150–250W) + 24″ monitor (25–35W) + router (10–15W) — approximately 45–60 minutes runtime
• Wi-Fi router + managed switch + NAS device — 3–5 hours runtime
• 65″ OLED/QLED TV + DStv decoder + soundbar — approximately 1–2 hours runtime

Note: runtime depends on actual load. Reduce connected devices to extend backup duration during extended outages.
