Overview

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.

Technical Description

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.

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.

Additional Compatibility Information

Enclosure Considerations

A desiccated, non-condensing environment is required. The PS100 includes built-in keyhole flanges for mounting to the backplate of a Campbell Scientific enclosure.

Adapters

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.

Charging Source

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.

  1. Look for a stamp on top of the battery. The stamp may be in a date format of YYMMDDXX where:

    • YY is the year.
    • MM is the month.
    • DD is the day.
    • XX is the manufacturing plant.

    This indicates the age of the battery.

  2. 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.

  3. Yes. However, Campbell Scientific recommends connecting a PS100 battery to a wall charger overnight before using it in the field.

  4. Yes. A deep-cycle RV or marine battery can be used. To make it work correctly, however, it may be necessary to purchase the 6186External Battery Cable for Rechargeable Power Supplies.

  5. 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.

  6. Yes. The PS100 can be continuously connected to the 29796 or 9591 wall charger on ac power.

  7.  To connect the PS100 and the deep-cycle marine or RV battery, use pn 6186, External Battery Cable for Rechargeable Power Supplies.

  8. Although the SP20 delivers approximately 1.17 A in full sun, the limit of the PS100 is approximately 1.2 A. Therefore, Campbell Scientific does not recommend connecting a PS100 to a solar panel larger than 20 W. In comparison, the PS200 and CH200 can be connected to solar panels as large as 70 to 90 W.

  9. 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.
