The V-I (Voltage and Inductance) curve (see Figure 44) shows the performance characteristics and modes of operation of the Liebert FS system based on the seven user-configurable system parameters.

Regulation Voltage Delta During Discharge (Vreg Delta 1)

Vreg Delta is the programmed amount of voltage drop from the beginning of discharge (SOC = 100%) to the Vreg Delta TSOC.

Range—from 0 to (Vreg - 250) VDC

(Ex: if Vreg = 500, then the Vreg Delta1 can be set between 0 and 250 VDC)

Default setting—0 VDC

Regulation Voltage Delta Transition at State of Charge (Vreg Delta T SOC)

Range—0-100%

Default setting—0
