Sentry Battery Chargers Sentry Battery Chargers are available in a wide range of models and are offered in both switchmode (SM) and Ferro-Resonant (FR) technologies SM Battery Chargers
The Sentry switchmode chargers are designed for unattended operation. When current is requested or the battery needs charging, the Sentry SM charger responds with the required output. The three-step charger brings your battery up to full charge very quickly. When the battery reaches a float condition, output is reduced to match that requested by the battery. The unit also acts as a power supply to operate your 12 or 24 VDC systems directly, should the need arise. Flexible Sentry SM-Series Chargers are available in 12 and 24V models in capacities ranging from 10 to 120 amps. Most models can be set for 115 or 230 VAC operation with a simple internal adjustment. They can accommodate 50 or 60 Hz power with automatic switchover. Some larger capacity chargers must be ordered for 115 or 230V input. The chargers can work efficiently with low supply voltages and poor-quality AC waveforms from generators. An easy manual switch is used to select output for gel cell or lead acid batteries. Most Sentry SM models offer three indpendent outputs for charging three separate battery banks simultaneously. The 12V, 10 and 20 amp models provide two outputs. Easy Operating the Sentry SM charger couldn't be easier. You turn it on and leave it on. That ís all. Convenient front panel indicators give a readout of system status. An optional indicator panel is also available on most models for remote mounting. Quality The Sentry SM chargers are built to ABYC and UL standards and are CE certified for export to Europe. They are designed with protection against over temperature and short circuit, and are equipped with input and output fuses. They are ignition protected and current limited.
FR Battery Chargers
Sentry FR-series chargers are designed for totally automatic, unattended operation. All you have to do is set the front-panel switch to "automatic", and the Sentry charger takes over. It monitors all battery banks. Whenever it senses a drop in voltage to the cut-in level, the charger comes on, maintaining the load of your DC system while taking care of your batteries. As the battery approaches full charge, the Sentry's ferro-resonant transformer gradually tapers back the charging current. Then the charger turns itself completely off until it's needed again. When it's off, it's completely off. There's absolutely no output trickle to overcharge and dehydrate, damage or warp your batteries' cell plates Wide Range of Choices. Sentry FR-series chargers are available in a wide range of 12V, 24V and 32V models, with output current ranging from 20 to 60 amps. Standard input power is 115 or 230 VAC power. Models are available for 50/60 Hz operation. Standard Sentry units have negative ground with triple output, permitting up to three separate banks of batteries to be charged simultaneously. A fourth output is available on some larger models. A manual/automatic selector switch, ammeter, full charge and power indicator are conveniently located on the front panel. Reliability Is Built In. Sentry FR chargers are designed for dependable operation in a hostile environment, providing continuous operation in hot engine compartments at temperatures up to 122° F (50° C). The units compensate automatically for fluctuations in dockside voltage. Fifteen percent change in input causes one percent change in output. All models are current limited, and fully ignition protected. The charger has an auto reset DC breaker, allowing the automatic recharge of severely depleted batteries. Isolation-type step-down transformers eliminate the possibility of electrolysis. All products meet applicable yacht safety standards. Contact Airon for Sentry marine battery chargers and accessories.
