Hardware Specifications
Specifications in Table A-1 are warranted. Specifications apply over an ambient temperature range of 0°
C to 40° C. When charging, specifications apply for charging voltages from 0.5 V to maximum, and
charge currents from minimum to maximum. When discharging, specifications apply for discharging
voltages from 1.5 V to maximum and discharging currents from minimum to maximum. Accuracy
specifications apply over the entire range of ac line and power bus conditions (line regulation), and
charging/discharging levels (load regulation). Specifications are subject to change without notice.

There is a minimum programmable current limit when operating in constant current (CC) mode. In CC mode, the output cannot
be set to run below the minimum programmable constant current limit specified in Table A-2. In constant voltage (CV)mode,
charging or discharging, the MCCD will regulate current down to 0A.
