Standard Output Calibration

Output Calibration Information

Battery type is selected by circuit board DIP switches or SNTL300P-PCSUITE configuration software.

Calibration figures at 20 ºC. If temperature compensation is enabled, and remote SNTL-RTC temperaturesensor connected, output voltage automatically varies by 3 mV per cell per 1 ºC deviation from 20 ºC, within the range -10 to +50 ºC. Increasing temperatures give decreasing outputs; decreasing temperatures give increasing outputs.

AutoBoost

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

Temperature Compensation

Microprocessor programmability for automatic or manual configuration of charge output voltages (12 or 24 V 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.

Flexible Configuration

Flexible Configuration

For remote charger control, and signaling 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

Display, Instrumentation and Communication

Options for backlit LCD readout, analogue metering and CAN 2.0B/SAE J1939 data communication; all models include RS485 communication for 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.
