    power applications

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 vented 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,
•  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.
•  AutoBoost maximizes cell capacity and life.

In addition, the Sentinel 300P includes:
•  Flexible configuration: microprocessor programmability for automatic or manual configuration of charge output voltages (12 or 24V nominal), cell types/numbers and application – all in one standard model. •  Programming is by circuit board links or PC-based software configuration and monitoring tool.
•  Inputs & outputs: for remote charger control, and signalling of charge fail, high/low battery volts and mains fail faults. Standard output functions are NFPA 110 compliant. Non-standard input/output functions available to special order.
•  Display, instrumentation and communication: options for backlit LCD readout, analogue metering, plus RS485 and CAN 2.0B / SAE J1939 data communication, configuration and control.

The Sentinel 300P is available either as an open-frame, UL-recognized module for mounting in existing control panels, or as a UL-listed, wall-mounted stainless steel enclosure with LCD and analogue metering options. Electrical connection is by screw terminal blocks. On enclosed models, wiring harness access is by knock-out cable gland holes in the case side.

Battery type is selected by circuit board DIP switches or SNTL-PCSUITE configuration software. Calibration figures at 20 deg C. If temperature compensation is enabled, and remote SNTL-RTC temperature sensor connected, output voltage automatically varies by 3mV per cell per 1°C deviation from 20°C, within the range –10 to +50°C. Increasing temperatures give decreasing outputs; decreasing temperatures give increasing outputs.
