Sentinel 300P Series Battery Chargers
Sentinel 300P Series Battery Chargers

FEATURES

  • Microprocessor controlled, programmable battery charger
  • High rate, low ripple float charging: 10A @ 12/24 VDC
  • Auto boost and temperature compensation
  • Options for RS485/CAN connectivity, backlit display and analog meters
  • Panel mount module or wall mounted, stainless steel enclosure
  • For stationary engine, genset and standby power applications

 

DESCRIPTION

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 auto boost 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.

 

  • AUTO BOOST: triggered automatically on low charge levels, or manually by remote switch, auto boost 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.

 

In addition, the Sentinel 300P includes:

 

  • FLEXIBLE CONFIGURATION: microprocessor programmability for automatic or manual configuration of charge output voltages (12 or 245 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.

 

  • INPUTS & OUTPUTS: 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 inout/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.
