Sentry Battery Chargers

murphy.sentryThe Sentry UL battery charger provides automatic, current limited and thyristor controlled charging of vented lead acid or NiCd batteries. It may be used in a wide range of industrial charging applications, including standby engines, pumps and generators.

The charger is supplied in a wall mounted stainless stell enclosure, complete with DC ammeter indication. Each unit consists of a transformer, rectifier and control circuit. The control circuit ensures that the charger maintains a battery voltage at the pre-calibrated float level, while supplying any additional load current up to the specified maximum.

When used as a float charger, the unit is designed to give a constant current output while battery voltage is below 'knee-point' (approx. 13V for 12V lead-acid batteries). Above the knee-point, as the battery approaches its float voltage, the Sentry output current ramps down. This multi-stage charge regime gives a fast charge rate, followed by float charge without overcharging.

Nominal operating voltages: 120V units
Permissible voltage variation: ± 6% of nominal
Nominal operation frequency: 50-60Hz

DC Charge Output:
Maximum current ADC: 5

Guardian Battery Chargers

murphy.guardianThe Guardian UL is a highly efficient, high performance battery charger. The output is configured for accurate fast charging, optimum battery life and reliability. High impedance transformer technology gives a low ripple output (<1%) for optimal charging of vented or sealed lead acid or NiCd batteries. The charger, typically wall mounted in its stainless stell enclosure, may be used in a wide range of industrial charging applications, including standby engines, pumps and generators.

The Guardian consists of a transformer, rectifier and control circuit with DC ammeter and voltmeter. The control circuit ensures that the charger maintains a battery voltage at the pre-calibrated float level, while supplying any additional load current up to the specified maximum.

The auto boost operation provides a temporary increase in output voltage, equalizing the battery charge between cells and maximizing battery life and capacity. Auto boost is triggered automatically when the battery falls below a preset voltage, and can also be triggered manually by linking two ‘boost’ terminals, e.g. using a panel switch or push-button. Once the batteries have reached the boost voltage level, Guardian reverts to its normal float charge mode, preventing battery over-charge and gassing.

Power Supply:
Nominal operating voltages: 120VAC ± 6%
Permissible voltage variation: 120VAC ± 6%
Nominal operation frequency: 50-60Hz

DC Charge Output:

Sentinel 150 Battery Chargers

murphy.sentinel150Sentinel 150 UL approved automatic battery chargers are highly efficient, high performance battery chargers, designed 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 efficiency and 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. All models features an intelligent, multi-stage charge regime: during charge recovery mode, the Sentinel gives a constant (maximum) current output; as the battery approaches peak charge, the output reverts to float charge mode, maintaining an optimum cell voltage and supplying additional standing load current up to the rated maximum. Output current is always limited to the rated maximum, even during high load (e.g. engine cranking), short-circuit or reverse polarity connection.

Specifications:
Operating voltage: 95 to 250 V AC
Operating frequency: 47 – 63 Hz.
Nominal voltage: 12 or 24 V DC
Maximum current limit: 5 A (12 and 24V models) or 10 A (12V models)

Sentinel 300 Battery Chargers

murphy.sentinel300Sentinel 300P battery chargers provide new levels of DC power control, monitoring and protection for stationary engine starting and standby battery applications. Standard features include switch mode charging technology, a high power efficiency and low heat dissipation, plus wide supply voltage tolerance, in a compact and lightweight package. Multistage charging includes float, bulk, absorption and auto boost stages to ensure no compromise between rapid charge recovery and long term battery capacity and life.

The very smooth output (< 1% ripple) allows charging of sealed or vented batteries – e.g. Nickel Cadmium (NiCd), Lead Acid sealed (VRLA), and vented lead acid – and is configurable for use as a stand-alone DC power supply. The auto boost feature triggers automatically on low charge levels, or manually by remote switch. Auto boost temporarily increases the charge voltage before returning to float mode, which equalizes the battery cell charge without overcharge and gassing. Auto boost also maximizes cell capacity and life. The Sentinel 300P's temperature compensation feature ensures batteries are charged at the optimal voltage, which varies significantly with ambient temperature. The charger 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 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. Optional backlit LCD readout, analogue metering, plus RS485 and CAN 2.0B / SAE J1939 data communication, configuration and control are offered in some models.

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.
