Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure The PS24 Power Supply is typically used when a solar-powered ET107 transmits data via an RF450 Spread Spectrum Radio or cellular phone. However, the PS24 can be used for any situation where a larger capacity battery is desirable. B.1 PS24 Components The PS24 consists of a 24 Ahr rechargeable battery, CH100 regulator, and a 10 inch x 12 inch environmental enclosure (see FIGURE B-1 through FIGURE B-3).
