DCDC18R 12 to 18 Vdc Boost Regulator

Overview

The DCDC18R Boost Regulator accepts an 11 to 16 Vdc input and boosts it to 18 Vdc, allowing a vehicle to recharge CR3000, CR5000, or CR23X sealed rechargeable batteries. The DCDC18R conveniently attaches to the side of the sealed rechargeable base next to the charger input.

Frequently Asked Questions

Number of FAQs related to 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 datalogger (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.
