Campbell Scientific offer power supplies with either alkaline or lead-acid batteries.

Alkaline Packs

The BPE-ALK uses eight alkaline D-cells. It incorporates a low voltage drop diode to prevent any paralleled battery discharging into the alkaline cells. A fresh set of eight alkaline D cells provides 12.4V to the datalogger with a nominal rating of 10Ah capacity at 20°C.

Solar Panels

A choice of 3 models offering 5W, 10W and 18W of power are offered. These are typically used to maintain a float charge on a lead acid pack to power remote weather stations and other monitoring systems in situations where mains power is not available.

Lead Acid Packs

The following 12V  power sources are available and all include housing and charger circuit:

     PS100E-LA 7Ah 
     BP17E-LA 17Ah  
     BPE24-LA 24Ah 
 
The PS100-A100 12V lead-acid power supply offers a charging regulator and Null Modem Ports, used when 5V is needed to power external modems, in addition to the normal capabilities of the PS100E-LA. A common use for the PS100-A100 is in radio telemetry networks. 

The CR200 series dataloggers have a built-in battery charger. These dataloggers use a PS200E-LA 12v battery - a lower-cost variant of the PS100E.

PS200 & CH200 Smart Charging Regulator and Power Supply

The PS200 and CH200 are microcontroller-based smart chargers with two-step constant voltage charging and temperature compensation that optimize battery charging and increases the battery's life. Two input terminals allow simultaneous connection of two charging sources.

PS100 & CH100 Rechargeable Power Supplies and Charging Regulator

The PS100 and CH100 are 12V DC power supplies for our CR200X, CR800, CR850, CR1000 and older dataloggers and peripherals. They can also be used as a separate auxiliary 12V power supply to power remotely located sensors or peripherals, such as a multiplexer located at a distance from the datalogger enclosure.
