Sentinel 300P Series Battery Charger

Sentinel 300P battery chargers provide new levels of DC power control, monitoring and protection for stationary engine starting and standby battery applications.

Advanced Sentinel charging features included as standard:

• Switch mode charging technology: high power efficiency and low heat dissipation, plus wide supply voltage tolerance, in a compact and lightweight package.
• Multistage charging: float, bulk, absorption and AutoBoost stages ensure no compromise between rapid charge recovery and long term battery capacity and life.
• Low output ripple: <1% ripple, beneficial for wet lead acid & NiCd cells, essential for VRLA, and configurable for use as a stand-alone DC power supply.
• AutoBoost: triggered automatically on low charge levels, or manually by remote switch, AutoBoost temporarily increases the charge voltage before returning to float mode. Equalizing battery cell charge without overcharge and gassing, AutoBoost maximizes cell capacity and life.
• Temperature compensation: ensures batteries are charged at the optimal voltage, which varies significantly with ambient temperature. Sentinel can measure temperature with a battery mounted sensor, and adjusts output voltage to prevent under or over charging.
