OUTPUTS
VOLTAGE: 24, 26, 28, and 48 VDC
CURRENT: See Tables
ADJUSTMENT RANGE: +5 to –10% of nominal output voltage.
POLARITY: Output is isolated. It may be referenced plus/minus as
required.
REMOTE SENSING: Compensates for up to 0.5V total loop drop
in the output line.
STATIC REGULATION: Line: +/- 0.25% over full line range.
Load: Option: =/-% zero load to full load. Droop IFE: Option:
the output sags from +5% when the load is increased from 10% to
100%.
VOLTAGE STABILITY: +/-0.1% FOR 24 hour period after 30
minute warm up.
OUTPUTS
TEMP COEFFICIENT: +/-0.02%/ C FROM 0 c TO +50 c.
P-P RIPPLE AND NOISE: 1% (20Hz to 50MHz Bandwidth).
MINIMUM LOAD: Not Required.
TURN ON DELAY: 1 sec. Max from application of AC line.
OVER VOLTAGE PROTECTION: 125% +/-5% of nominal. OVP
shutdown is latched until the input line is removed for 5 secs and
then reapplied. OVP sensing is don at the output terminals.
OVERCURRENT PROTECTION: Current l=Limit Point: 110% to
120% of full load.
