PCE M8-700 UPS (line-interactive) — 700 VA / 360 W backup unit for 220–240 V input. Protects PCs, routers, small electronics from outages and voltage swings. The PCE M8-700 is a line-interactive UPS designed for home or small office use. It provides backup power, voltage regulation (AVR), surge protection, and supports automatic switching during outages. Ideal for desktop PCs, network gear, monitors, or point-of-sale systems. Features & Capabilities Line-interactive topology: regulates input voltage without switching to battery when voltage fluctuates mildly. Automatic Voltage Regulation (AVR) to correct undervolt/overvolt conditions. Simulated (stepped) sine wave output in battery mode. Surge, overload, short circuit, discharge protections built in. Cold start capability (ability to power on from battery with no mains) LED + audible alarms for status (battery mode, overload, fault) USB / RS232 interface in some variants for power management (shutdown, monitoring) Technical Specifications What “Input 220–240 VAC, 50/60 Hz, 3.7 A” Means (and Caveats) If the specification you’re giving is “3.7 A” at input, that corresponds to a maximum input current draw when the UPS is handling a heavy load or during charging cycles. At 230 V × 3.7 A ≈ 850 W of input capacity. The unit’s 360 W output means there’s overhead for losses, inverter inefficiency, battery charging, etc. The UPS must operate within the stated voltage and frequency ranges — if input is too low or too high, it may switch to battery or go into protection mode.
