Product information

Description

KEMOT PROsinus-500 is a 500VA power inverter that converts 12V DC to 230V AC with a pure sine wave output. It is intended to supply heating boiler feed pumps and fans during mains supply interruptions; backup duration depends on the connected battery capacity. The inverter is compatible with lead‑acid (Pb) batteries rated 12V and between 18–120Ah.

Advantages

The pure sine output delivers a stable, low‑distortion AC voltage suitable for sensitive electronics and inductive loads such as pumps and fans. With a compact 500VA rating it supports small household devices and charging equipment while offering straightforward connection to a 12V Pb battery bank. The unit provides automatic DC to AC conversion and reliable backup power during supply failures.

Suitable for

  • Heating boiler feed pumps
  • Boiler circulation fans
  • Small household appliances within 500VA
  • Chargers and audio/video equipment requiring pure sine power

Key specifications

  • Output power: 500VA
  • Input voltage: 12V DC
  • Output voltage: 230V AC, pure sine wave
  • Compatible battery type: Pb (lead‑acid)
  • Supported battery capacity: 18–120Ah
  • Manufacturer: KEMOT, MPN: URZ3408

How to use

Connect the inverter to a 12V lead‑acid battery (18–120Ah) according to the manufacturer’s wiring instructions, then connect the boiler pump or fan to the 230V AC output. Ensure battery polarity is correct and that battery capacity is sufficient for the expected backup duration. Turn on the inverter to provide AC power when mains supply fails or to run devices from the battery.

Usage recommendations

Use an appropriately sized Pb battery and observe safety precautions: secure connections, correct polarity, and adequate ventilation. Do not exceed the 500VA continuous load rating and consult boiler documentation to confirm compatibility with a pure sine inverter.
