FIGURE 3-2. DCDC18R on CR5000
The DCDC18R is installed near the datalogger, either on the side of the
datalogger (FIGURE 3-2 ) or to the back panel of the enclosure. The voltage
input is connected to 12 volts and ground from the supply source. The leads
from “V out” go to the charging input. The G lead from “V out” connects to
either charge input terminal and the 18 V lead connects to the other. The
polarity of the inputs does not matter.
4. Grounding
The datalogger must be grounded for its transient protection
to work. CONNECTIONS TO THE CHARGING INPUT DO
NOT PROPERLY GROUND THE DATALOGGER. The
Ground connection should be made at the grounding lug on
the wiring panel.
A full-wave bridge rectifier is included on the CR3000, CR5000, and CR23X
LA bases and the PS100. This creates a diode drop (0.7 V) between the
datalogger ground and the return side of the charging input (FIGURE 4-1 ). If
the datalogger ground (ground lug) and the return side of the charging input (G
terminal of the DCDC18R) are tied together through a wire, then the return
current to the DCDC18R will flow through this wire rather than through the
diode in the bridge rectifier. This is a valid connection and does not cause
