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.
