The Sentinel 150P is a range of highly efficient, high performance battery chargers, designed 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 efficiency and 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. Each charger's output can be OEM-configured for optimal charging of different cell types: vented/wet lead acid, Calcium-Calcium, sealed VRLA (AGM or Gel), NiCd or custom requirements. The very smooth output (< 1% ripple) allows charging of sealed or vented batteries, or use as a stand-alone power supply.

All models features an intelligent, multi-stage 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.

AutoBoost 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, and reverts to float mode automatically at the end of the boost cycle, preventing battery over-charge and gassing. N/A The optimum charge voltage for lead acid and NiCd batteries varies with ambient temperature. Sentinel can be configured to sense battery temperature from a remote sensor and automatically compensate the output charge voltage.
