PS100 12 V Power Supply with Charging Regulator and 7 Ah Rechargeable Battery

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

Note:
*Typically, a CR23X, CR3000, or CR5000 datalogger uses its integrated rechargeable base instead of the PS100. However, the PS100 can be used if the datalogger has a low-profile base or if the battery base has been disconnected.

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 datalogger. 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. 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.

  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, if this type of data is desired, a better option may be to use a PS200 instead of a PS100. The PS200 (or CH200) model has built-in sensors that can measure the flux into and out of the battery and then pass that information to the datalogger via an SDI-12 cable.

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

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

  6. 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.

  7. 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.

  8. 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.

  9. 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.
