IVT 920033 Charge Voltage Booster 12 V 30 A

Unlike standard battery chargers that stop at a fixed voltage, the IVT 920033 boosts the alternator voltage to the exact level your auxiliary battery needs, ensuring a full charge even on long cable runs or with voltage drops. This 30 A unit supports LiFePO4, Gel, AGM, and wet lead-acid batteries with three selectable output voltages.

Highlights

• Three output voltage settings: 14.2 V (LiFePO4), 14.4 V (Gel/AGM), 14.7 V (wet lead-acid)
• High 30 A output current, up to 430 W power
• Efficiency above 90%
• Temperature-controlled fan for reliable cooling
• Protection against overload, short circuit, overtemperature, and reverse polarity

In daily use

Install the booster close to the auxiliary battery, connect it to the alternator via D+ or a manual switch, and select the appropriate voltage for your battery type. The compact aluminum housing and screw terminals for up to 16 mm² cables make installation straightforward. Standby consumption is under 1 mA, so it won't drain your battery when idle.
