L'alimentation rechargeable PS100 délivre une tension de 12 Vcc, 7 Ah destinée aux périphériques et aux centrales de mesure CR500, CR510, CR800, CR850, CR10, CR10X et CR1000. La batterie rechargeable peut être rechargée via une alimentation secteur (nécessite un adaptateur secteur de type, AC-ADAPT en option) ou à partir d'un panneau solaire externe. L'utilisateur peut ajouter une batterie rechargeable externe.Lire la suite
Le PS100 peut également être utilisé comme un bloc d'alimentation distinct auxiliaire de 12 V destiné aux capteurs ou à des périphériques situés à distance, par exemple un multiplexeur placé à certaine une distance du coffret de la centrale de mesure. Toutefois, pour éviter les erreurs de mesure analogiques et les boucles de masse, les 0 du 12V des alimentations doivent être reliés.
Le PS100 remplace l'alimentation PS12E-LA. Le PS100 est de dimension légèrement plus petit que le PS12-LA. Il permet également l'accès à l'interrupteur d'alimentation et la LED sans enlever le couvercle de l'alimentation.

|CR3000 (obsolète)||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 (obsolète)||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.

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.
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.
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. The 7 Ah battery can be purchased locally to save on shipping costs. Purchase pn 17057, PS100 Power Supply with No Battery.
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.
To connect the PS100 and the deep-cycle marine or RV battery, use pn 6186, External Battery Cable for Rechargeable Power Supplies.
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.
