3.16 BATTERY (B OPTION) OPERATION
The Battery Charger Option (B suffix) adds a second switch-selectable voltage network to the
front panel. This permits the user to preset two different voltage regulation values corresponding
to “float” and “equalize” functions for battery charging applications. This option is available for
1000W HSP models covering 12V, 24V and 48V, and 1500W models covering 24V and 48V
nominal battery voltages.
When the Float-Equalize switch is set to FL (see Figure 3-7), the Float potentiometer adjusts the
output voltage; when set to EQ, the Equalize potentiometer adjusts the output voltage. The FL-
EQ position also determines which voltage is available at test point Vo. CAUTION: Adjusting the
non-selected potentiometer (e.g., FL potentiometer with switch set to EQ) can have adverse
effects, because an unknown output voltage will be applied to the load when the switch position
is changed. The fault detector window is altered to accommodate the normal range of battery
voltage from fully discharged to peak equalize charge as shown in Table 3-3.:
The programmed current limit (Imax) applies to both float and Equalize operation. If the M
option is also included, the meters operate as described above (see PAR. 3.15) except that the
displayed setpoint value is determined by the FL-EQ switch.
