1. SPECIFICATION
I .l GENERAL: This LORAIf@ Rectffier is designed to power a load while charging a battery in a positive grounded
system. This rectifier is listed by Underwriters Laboratories under standard 1012 for power conversion equip-
ment in a controlled environment.
1.2 OUTPUT RATINGS
12.1 Voltage: Float voltage is adjustable from 48 to 54 volts for f!oatfmg 23 or 24 cells of battery, Equalize
voltage is adjustable from float voltage to 57 vofts for equalizing 23 or 24 cells of battery. A front panel
mounted swffch selects float or equalfbe dfarge operation.
1.2.2 Regulation
(A) Static: Steady state output voltage remafns within *l/2 % of any voftage wffhff the range of 48.3 to
55 vofts for any load current from no load to full load for the input voltage and frequency range spec-
ified.
(B) Temperature Coefficient: Output voltage change does not exceed an average of 0.01% per degree
C within the ambient temperature range of 0" C to +50" C. Refer to paragraph 1 S.1.
(C) Dynamic: For a step load change of 250 amps wlhff the range of 5% to 100% of full load, the max-
imum voltage transient does not exceed * 5% of the initff steady state voltage. Recovery to within
steady state voftage regufatiin range does not exceed 200 milliseconds and all transient behavior
disappears wbhin 500 milliseconds. Refer to paragraph 13.1.

(A) voice band noise is less than 32 dbm wlth C-message weighting
(B) wide band noise does not exceed 500 MV peak to peak or 30 MV RMS over the frequency range of
10 Hz to 14 MHz Referto paragraph 1.51.
