The PS100 provides a 12-Vdc, 7-Ah rechargeable power supply for the CR500, CR510, CR800, CR850, CR10, CR10X, and CR1000 dataloggers and peripherals. The rechargeable battery can be trickle-charged from ac power (requires optional wall charger) or from an external solar panel. The user can add an external rechargeable battery.Read More
The PS100 can also be used as a separate auxiliary 12-V power supply to power remotely located sensors or peripherals, such as a multiplexer located at a distance from the datalogger enclosure. However, to avoid errors in analog measurements and ground loops, the power supplies must share a common ground.

Note: The following shows notable compatibility information. It is not a comprehensive list of all compatible or incompatible products.
|CR23X (retired)||Typically, a CR23X, CR3000, or CR5000 datalogger uses its integrated rechargeable base instead of the PS100. However, the PS100 can be used if the data logger has a low-profile base or if the battery base has been disconnected.|
|CR3000||Typically, a CR23X, CR3000, or CR5000 datalogger uses its integrated rechargeable base instead of the PS100. However, the PS100 can be used if the data logger has a low-profile base or if the battery base has been disconnected.|
|CR5000 (retired)||Typically, a CR23X, CR3000, or CR5000 datalogger uses its integrated rechargeable base instead of the PS100. However, the PS100 can be used if the data logger has a low-profile base or if the battery base has been disconnected.|
A desiccated, non-condensing environment is required. The PS100 includes built-in keyhole flanges for mounting to the backplate of a Campbell Scientific enclosure.
The PS100 is compatible with the A100 null-modem adapter and the A105 adapter for additional 12 V output terminals. The A100 Null Modem Adapter connects and powers two Campbell Scientific peripherals via two CS I/O 9-pin connectors configured as a null modem. This is useful in linking different communications technologies, such as telephone to radio, at sites that do not have a data logger. The A105 adapter may be used to provide additional 12 V and ground terminals where the power supply is used to power several devices.
The PS100 charges with a 24 V input. However, when the battery is discharged or the system is pulling high current (about 700 mA), the regulator overheats. This, in turn, limits the charging time because the regulator is heating up until it gets so hot that it shuts down. At this point, the regulator stops charging the battery until the regulator cools down and starts charging again. This cycle repeats until the battery is charged enough so that the regulator no longer overheats. For a system with a constant current drain of 0.7 A or higher, the PS100 is not able to keep the battery charged unless the input voltage is between 16 and 20 V. If the input voltage is between 16 and 20 V, the regulator outputs continuously up to a 1.2 A load.

Look for a stamp on top of the battery. The stamp may be in a date format of YYMMDDXX where:
This indicates the age of the battery.
Typically, the battery will filter out the noise that comes in over the ac wall transformer.
Yes. The 7 Ah battery can be purchased locally to save on shipping costs. Purchase pn 17057, PS100 Power Supply with No Battery.
No. The sole purpose of the red LED on the PS100 is to indicate that the solar panel or ac wall transformer is delivering power to the charge circuitry.
The PS100 is designed to follow the Yuasa recommended temperature curve for float-charging batteries. This gives a nominal charge voltage of approximately 13.7 V at 25°C. The design should follow the curve to within ±0.2°C or better.
The external battery can be as large as the BP84; however, there is still a limitation of a 1.2 A charging current, as well as other specifications of the PS100. If higher charging currents are needed, use the PS200, Smart Power Supply and Charge Controller, or pn 18529, 10A, 12 V, Morningstar Regulator.
Two different conditions can cause the battery to not hold a charge well:
Yes. However, Campbell Scientific recommends connecting a PS100 battery to a wall charger overnight before using it in the field.
The charging time is dependent on the size of the solar panel or wall charger, as well as the level of discharge of the battery.
