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). The battery should be recharged via ac power or solar power. An SP10
10-W solar panel, SP20 20-W solar panel, or 14014 Wall Charger is typically
used to recharge the battery. The environmental enclosure is mounted to the
ET107’s pole using the pn 18520 hanger kit.
