Nabíjačka batérií IVT 3-stupňová nabíjačka konštantným prúdom 12V/24V model 900018

IVT 3-Stage Constant Current Charger 12V/24V model 900018 is a mains-powered battery charger designed for lead-acid battery systems. The charger supports both 12 V and 24 V configurations and applies a three-stage charging algorithm—bulk, absorption and float—with constant current control to ensure safe and efficient charging and maintenance of batteries used in vehicles, backup systems and stationary installations.

Advantages

This charger delivers controlled constant current during the main charging phase, reducing stress on the battery and helping to restore capacity more effectively than uncontrolled charging. The three-stage algorithm prevents overcharging by switching to absorption and float stages as appropriate, which helps to prolong battery life and minimize maintenance. The unit is suitable for continuous connection to battery systems for float maintenance, providing reliable standby readiness for backup applications.

Key specifications

How to use

Connect the charger to a suitable mains outlet and select the correct battery voltage if applicable. Ensure battery terminals are clean and observe correct polarity when connecting the charger clamps to the battery. Start charging according to the device indications; the charger will perform bulk charging at a controlled constant current, then switch to absorption and finally float maintenance automatically. Monitor charging status via the unit's indicators and disconnect from mains only after the charger indicates completion or when performing battery maintenance.

Recommendations

Use this charger in well-ventilated areas and avoid charging in sealed compartments. For long-term standby batteries, keep the charger connected in float mode to maintain capacity and prevent sulfation. Verify compatibility with the specific lead-acid battery type (flooded, AGM, gel) and follow battery manufacturer temperature and charging specifications to achieve optimal service life.
