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.
The PS100 replaced the PS12LA power supply. The PS100 offers a slightly smaller footprint and height than the PS12LA. It also allows access to the Power Switch and LEDs without removing the lid of the power supply.

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible 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 (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.|
|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.
Yes. A deep-cycle RV or marine battery can be used. To make it work correctly, however, it may be necessary to purchase the 6186, External Battery Cable for Rechargeable Power Supplies.
Connecting a 55 W solar panel to a PS100 will not damage the PS100. However, the current passing from the solar panel to the battery is limited to a maximum of approximately 1.2 A. Therefore, the full benefit of the 55 W solar panel is not realized. A better option may be to use a 55 W solar panel with a PS200 or CH200.
Not directly. However, a DCDC18R Boost Regulator can be used to boost the voltage of the 12 V, 100 Ah battery up to the required 18 V.
Yes. On the order, specify pn 6182.
The LED will be off if the solar panel is missing or damaged, or if it is night-time. If the charging source is a wall charger, such as a 29796, the issue could be a loose connection, a power failure, or a bad wall transformer. To check the connection, try tightening the screws. To check for a power failure, try plugging another device into the wall outlet.
Yes. The 7 Ah battery can be purchased locally to save on shipping costs. Purchase pn 17057, PS100 Power Supply with No Battery.
The easiest way is to note the system voltage, which will be approximately 14 V when the sun is shining on the solar panel and the battery is full (depending on temperature, of course). When the 7 Ah battery is fully charged, the PS100 will limit the current to the battery to milliamps. An ammeter can be inserted in line with one of the solar panel or wall transformer lines to see if the current is very low.
The PS200 and CH200 have a feature that measures the battery current (amperage). If this feature is needed, consider purchasing the PS200.
To connect the PS100 and the deep-cycle marine or RV battery, use pn 6186, External Battery Cable for Rechargeable Power Supplies.
