III — SPECIFICATIONS (STANDARD)
The following specifications apply to all standard (no suf-
fix) HSF-PFC 100 Watt Series models. Table 1 lists the
specifications that differ for each model. Common specifi-
cations that apply to all standard models are listed in the
paragraphs following Table 1. Other models are also avail-
able; consult your Kepco representative for their specifica-
tions.
NOTE
: Common specifications apply to all models except
where otherwise indicated.
INPUT:
Voltage:
Nominal:120V a-c/240V a-c;
Range:
90-264V a-c;
125-370V d-c. (polarity insensitive)
Frequency: Nominal: 50-60 Hz; Range: 47-440Hz
(From 66 to 440 Hz leakage current may exceed
UL/VDE safety spec. limit.)
Current (nominal output at rated load):
1.4A a-c max
@120V a-c rms
1.2A max for 3.3V model
0.7A a-c max
@240V a-c rms
0.6A max for 3.3V model
Initial Turn-on Surge: cold start 25°C (First surge
only, not including the current flow into the EMI fil-
ter):
14A typ. @ 100 V a-c, 100% load
28A typ. @ 200 Va-c, 100% load
Power Factor: 0.99 typ. @100V a-c;
0.95 typ. @ 200V a-c.
Switching Frequency:
135KHz typical
STABILIZATION:
Source Effect (full load): 0.2% typ.; 0.3% max.
Range 90-132V a-c, 170 -264V a-c,
Load Effect (10% to 100% load change):
0.5% typ.; 1.5% max.
Temperature Effect: Range –10
o
to 71
o
C
0.5% typ.; 1.0% max.
Combined Effect (includes source, load, and
temperature effects):
0.9% typ.; 1.8% max.
Time Effect (1/2 hr-8 hr at 25
o
C):
0.2% typ.; 0.5% max.
RECOVERY CHARACTERISTICS:
A step load
change from 50% to 100% produces less than +4% output
excursion. Recovery occurs to 1% of the original
setting in <1 ms (load change t
r
or t
f
equal to or greater
than 50
µ
sec).
START-UP TIME:
500 ms. maximum @100V a-c
300 ms. typical @100V a-c
200 ms. maximum @240V a-c
100 ms. typical @240V a-c

(1) Derates same as Output Power.
(2) Current Limit is rectangular. After the overload is removed,
output is automatically restored.

(4) Peak current and thermal protection; applicable to 24V model only.
See Figure 1 for peak power requirements.
(5) Ripple and noise will be approximately 1.5 times higher when
operating temperature range is between –10°C to 0°C.
