Power Supplies for Data Loggers
Campbell Scientific offer power supplies with either alkaline or lead-acid batteries.
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.
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
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.
