Resumen
La PS100 consiste en una batería recargable de 12Vdc 7Ah y un circuito regulador de carga. Esta fuente de alimentación es adecuada para alimentar a nuestros dataloggers y periféricos. La recarga puede hacerse tanto con un adaptador a 220Vac como con un panel solar.

Descripción detallada
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, PS150, and PS200 models take in AC or DC power from a wall transformer or a solar panel. The internal regulator controls the charge to the battery to make sure the battery doesn’t become overcharged (based on temperature).
If the switch is on, the voltage from the battery will flow back out from the regulated battery to the loads; however, the voltage on that battery may be 11.9 V, 13.2 V, or some other value that the battery happens to be at. It is important to understand that the voltage will not always be exactly 12.0 Vdc. Rather, the voltage will float up or down as the battery is recharged or depleted.
-
The voltage from a solar panel will fluctuate throughout the day.
If AC power is being used, the voltage is usually stable.
The voltages coming into the regulator inputs are controlled so that the battery won’t be overcharged (and thus ruined by boiling out the electrolyte). If the battery connected to the regulator is good, the highest voltage you will likely see is just above 14 Vdc in the extreme cold, but normally it should be around 13.2 Vdc.
If you have a nearly dead battery (to be checked with a voltmeter) or a battery with shorted cells, you will see a very low battery voltage. The lowest voltage you will see on the data logger data is usually about 10.0 V because the data logger will shut down near that level and then wait for the voltage to increase to an 11- or 12-volt level.
The ripple voltage is a few millivolts flowing into the battery, but the battery should filter out most of that noise, providing a pretty stable voltage.
-
Yes. The G and 12V terminals on the charge regulator are used to connect the black and red wires that connect with the green connector, which provides power to the data logger.
-
Look for a stamp on top of the battery. The stamp should 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.
To evaluate the condition of the battery:
- Charge the battery.
- Let the battery sit for a couple of hours.
- Measure the open circuit voltage to get an estimated indication of condition.
-
Most would terminate the ac line in an ordinary duplex receptacle box inside the enclosure. It is not recommended that you use the same conduit access hole that your signal leads are fed through, as that may induce unwanted noise in your signals. Then, simply connect the 9591 wall transformer from the receptacle to the PS100 charge terminals. The PS100 (or CH100) expects either 18 Vac or 18 Vdc that's limited to no more than 1.2 amps.
-
Typically, the battery will filter out the noise that comes in over the ac wall transformer.
-
Yes. However, Campbell Scientific recommends connecting a PS100 battery to a wall charger overnight before using it in the field.
-
Yes. The 7 Ah battery can be purchased locally to save on shipping costs. Purchase pn 17057, PS100 Power Supply with No Battery.
-
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.
-
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.

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.
