FILTERING
Single phase units are 30Mv. RMS and three phase units are 100Mv. RMS when connected to a battery
with an ampere-hour capacity of four times the output current capacity of the charger (32 DBRN “C”
message weighting on unit’s 48 volts or less).
2.6
MEAN TIME BETWEEN FAILURE

STANDARD FEATURES
5.1
INPUT PROTECTION:
AC BREAKER
Single Phase Units -
A two-pole circuit breaker opens both sides of the
a.c. service for 120-208 or 240 on single phase
models, 50 amps or less.
Three Phase Units -
A three-pole circuit breaker opens all three legs of
the a.c. service.
5.2
OUTPUT PROTECTION:
A two pole d.c. breaker is provided on all 50 amp or less units.
Current limiting is adjustable from 90% to 120% of rated load, limits the d.c. output current. Factory
set at 115% of rated output.
