KEMOT URZ3409 UPS / Pure Sine Wave Inverter (800 VA / 500 W)

The KEMOT URZ3409, also known as the PROsinus‑800, is a 12 V DC UPS and pure sine‑wave inverter designed to provide reliable backup power for sensitive electronics, pumps, heating systems, and other devices during power outages. It converts DC from an external 12 V battery into stable 230 V AC output with a pure sine waveform, ensuring proper operation of connected devices. The unit also charges the battery when mains power is available. Note: External battery is required (not included).

Features

• Pure sine‑wave output: Provides clean 230 V AC power suitable for sensitive electronics and inductive loads.
• 12 V DC operation: Works with external 12 V lead‑acid or compatible batteries.
• UPS and inverter modes: Delivers backup power during outages and charges the battery when mains is present.
• Fast switchover: ≤ 4 ms transfer time from mains to battery power.
• LED status display: Shows input/output voltage, battery level, and load level.
• Protection features: Safeguards against overload, short circuit, overvoltage, undervoltage, and extreme conditions.

Benefits

• Ensures pure sine‑wave AC power for computers, pumps, boilers, and other sensitive devices.
• Prevents overheating or malfunction of inductive loads.
• Automatic switching and battery charging make it convenient for standby power setups.
• LED display provides clear operational status.
