12 Ahr and 24 Ahr Power Supplies
Th e BP12 and BP24 are battery packs for powering systems1 that have higher current drain equipment such as satellite transmitters. Th ey consist of a rechargeable battery, enclosure mounting bracket, and cables. Th e BP12 and BP24 require a regulated charging source (provided by the CH100 or CH200 regulator connected to an unregulated solar panel or a wall charger). Regulator Th e regulator controls the current fl owing to the battery and prevents the battery current from fl owing to the charging source. A regulator is required to connect the BP12 or BP24’s sealed rechargeable battery to an exter- nal charging source (e.g., solar panel, wall charger). Th e CH100 regulator is for standard applications. Th e maximum charging current of the CH100 is 1.2 A, which means that the largest solar panel that can be used is an SP20. Th e CH200 is a microcontroller- based smart regulator with two- step constant voltage charging that optimize battery charging and increases the battery’s life. It has input terminals that allow simultaneous connection of two charging sources. It also mea- sures various input, output, and status parameters to allow close monitoring of the battery. Th e SP70 70-W solar panel can be connected to the CH200. Integrated Power Supply Th e PS24 consists of a 24-Ahr sealed rechargeable battery, CH100 regulator, enclosure mounting bracket, power cable, and a 10” x 12” environmental enclosure. Th is power supply is intended for systems such as the ET107 where the weather station’s enclosure is not large enough to house a BP24 battery. Th e enclosure has one conduit for cable entry and several options for mounting it on a tripod or tower. Th e battery should be recharged via a charging source (see below). Accessories Charging Sources Several wall chargers and solar panels are off ered for recharging the batteries (see Ordering Information). Solar panels charge batteries by converting sunlight into direct current. Wall chargers use power from external ac power lines to recharge the batteries. Adapters Campbell Scientifi c off ers two adapters that fasten onto our regulators. An A100 adapter used with a regulator and a battery pack can power periph- erals and external devices at nondatalogger sites such as repeater stations. Th e A105 adapter increases the number of 12 V and ground terminals available on the regulator. Th e A100 and A105 cannot be connected to the regulator at the same time. Above shows the PS24’s enclosure, CH100, power cable, and battery bracket. The battery is shipped separately, and must be installed by the user. The BP12 (shown above) and BP24 include a bracket for mount- ing to the backplate of an ENC16/18 enclosure. The 27758, an optional BP12 mounting kit, is also off ered if more secure mounting is required. 1Information about calculating power usage is included in our Power Supply Overview brochure and Power Supply application note.
