Pure sine wave UPS 500VA/300W for central heating boiler, 12V, Kemot URZ3408

Pure sine wave inverter, designed for equipment sensitive to voltage waveform: circulation pumps, convector automation systems, central heating boilers with control electronics. A pure sine wave means that motors and control circuits receive exactly what they get from the grid, without harmonics that shorten their lifespan or cause noisy operation.

Switching to battery power occurs in under 4 ms, below the threshold at which most equipment detects an interruption. The battery (12V, not included) charges at up to 10A, so a 7-9Ah battery recovers quickly after a short outage.

• Inverter power: 300W / 500VA
• Battery voltage: 12V DC (max. 15V DC)
• Input voltage: 180-275V AC, 45-60Hz
• Output voltage: 230V AC ±8%, 50/60Hz ±0.5Hz
• Output waveform: pure sine wave
• DC-AC conversion efficiency: ≥85%
• Maximum battery charging current: 10A
• Switching time: ≤4ms
• Output sockets: 2x Schuko
• Protections: overload, short circuit, overvoltage/undervoltage
• Operating temperature: 0-40°C
• Humidity: 10-90%
• Dimensions: 25.5 x 26 x 16 cm
• Weight: 4.7 kg

Compatibility: central heating boilers with circulation pumps, convector automation systems, any 230V AC equipment sensitive to voltage waveform and with a continuous consumption of under 300W.

Good to know: the 12V battery is not included. Autonomy depends directly on the capacity of the chosen battery and the power consumption of the connected equipment; for a typical 80-150W central heating boiler, a 17-20Ah battery provides several hours of operation.
