概览

DCDC18R升压直流转直流模块接受11-Vdc到16-Vdc的输入压电,提升到18 Vdc输出。因而可以通过它使用汽车电瓶给CR3000、CR5000、CR23X的密封可充电电池充电。DCDC18R可以方便的附在密封可充电底座的靠近充电输入端子的一侧。

Enclosure Considerations

A desiccated, non-condensing environment is required. The DCDC18R includes built-in keyhole flanges for mounting to the backplate of a Campbell Scientific enclosure.

常见问题解答

DCDC18R: 1

  1. The CR3000 rechargeable lead-acid battery base requires more than 16 Vdc to properly charge the batteries. The DCDC18R Boost Regulator was designed for this purpose. Failure to use the DCDC18R with the lead-acid rechargeable battery base will result in permanently damaged batteries. (The batteries will remain below deep-discharge levels.)

    The CR3000 internal lead-acid batteries are used whenever the car battery is too low to power the data logger (less than 11 V). For example, when the engine is turned off or during start-up when the vehicle battery voltage drops due to starter current demands.
