NGBC-R3

Operation Guide

Thank You for purchasing another quality GSL Product. This Micro Controlled Booster Charger has been designed to 
overcome the limitations of most auxiliary charging systems. 

The NGBC1222 is a Next Generation full 3 stage 22Amp Charger which will operate from voltages as low as 11.5Volts up 
to 15.5Volts whilst still providing optimal charge to a variety of lead acid and lithium battery chemistries. Feature rich unit 
incorporates revolutionary new concepts in battery charging. 
Featuring:

Optional:

 Automatic Start Assist - Using a solenoid (Sold Separately on NGBC1222-1) will automatically jumpstart from an axilliary battery.

• Constant Output Power Limiting - Giving you more charging current when auxilliary battery is low (Up to 25A

 output)

 Thermal Compensation - Via optional external LM series sensor. (For Lead Based Batteries Only) 

 Automatic voltage drop compensation - calculates and overcomes voltage drop on long wire runs. 

• Polymer Encapsulation - 

Weatherproof convection cooled aluminum construction. 

• High Operating

 Temperatures - Safely work up to 70°C. Full power output to 45°C with gradual power degrading to 70°C
