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.

Detailed 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 data logger enclosure. However, to avoid errors in analog measurements and ground loops, the power supplies must share a common ground.

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.
CR295X (retired)
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.
CR500 (retired)
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.

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.

Frequently Asked Questions

Number of FAQs related to PS100: 28

Expand AllCollapse All

  1. 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.

  2. Yes. The 7 Ah battery can be purchased locally to save on shipping costs. Purchase pn 17057PS100 Power Supply with No Battery.

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

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

  5. Two different conditions can cause the battery to not hold a charge well:

    • The battery could be getting old and needs to be replaced.
    • The system load could be higher than expected. Look for faulting cabling, failed sensors, or configuration changes on telemetry devices or in the program of the data logger.
  6. 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.

  7. 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.

  8. Campbell Scientific recommends letting an idle PS100 charge continuously in an ac power setting. If solar panel power is being used, the daily cycle is expected.
