RS PRO 12V 5A Battery Charger

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.

Switch mode power supply technology: light and compact, power efficient with low heat dissipation
Multi-stage, low ripple charging: 12V/5A (RS 885-3663) or 24V/5A (RS 885-3672)
Versatile: OEM-configuration gives optimized output for different battery types, plus programmable I/O functions
AutoBoost and temperature compensation
Open-frame with protective cover, for surface mounting inside a panel
For stationary engine, genset and standby power applications

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.

Both 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

RTC sensor for remote temperature compensation feature, complete with 3m/9.8ft lead assembly (RS 885-3688)
SNTL150P-PCCONN programming kit. Includes SNTL150P-PCSUITE software tool (PC compatible) (RS 885-3681)

Standard Sentinel (SNTL150) models feature a compact case for surface (or optional DIN rail) mounting inside existing control panels
