The Sentinel 150 line provides high performance battery charging for continuous float charge and standby power applications. Switch mode technology provides major advances in power supply and battery charger design, giving a compact and lightweight construction, improved power efficiency, low heat dissipation, wide supply voltage tolerance and low output ripple.

The chargers are configured for fast, accurate charging to give optimum battery life and reliability. The very smooth output (<1% ripple) allows charging of sealed or vented batteries - e.g., Nickel Cadmium (NiCd), Lead Acid Sealed (VRLA), vented and Planté cells - or use as a stand-alone power supply. Factory calibration is optimized for each specific battery type.

Output Calibration Information N/A Calibration figures shown are at 20 ºC. If temperature compensation is enabled and remote SNTL-RTC temperature sensor is connected, output voltage automatically varies by 3 mV per cell per 1 ºC deviation from 20 ºC, within the range -10 to 50 ºC. Increasing temperatures give decreasing outputs; decreasing temperatures give increasing outputs. N/A

AutoBoost provides a temporary increase in output voltage, equalizing the charge between cells and maximizing battery life and capacity. AutoBoost is triggered automatically when the battery falls below a preset voltage or can be initiated manually through a momentary switch input. At the end of the AutoBoost cycle, Sentinel automatically reverts to normal float charge mode, preventing battery over-charge and gassing.

Features N/A All models feature an intelligent, multistage charge regime. During charge recovery mode, the Sentinel gives a constant (maximum) current output. As the battery approaches peak charge, the output reverts to float charge mode, maintaining an optimum cell voltage and supplying additional standing load current up to the rated maximum. Output current is always limited to the rated maximum, even during high load (e.g., engine cranking), short-circuit or reverse polarity connection. N/A
