III — SPECIFICATIONS
The following specifications apply to HSF-1UR 100 Watt
Series models (also refer to Table 1). Other models are
also available; consult your Kepco representative for their
specifications.
INPUT:
Voltage: 100-120V a-c, 200-240V a-c nominal;
Range 95-264V a-c; d-c range: 125-370V d-c.
Frequency: Nominal 50-60 Hz; Range 47-440Hz
(from 66 to 440Hz leakage current exceeds UL/
VDE safety spec. limit).
Current (nominal output at 100% load):
@100-120V a-c rms: 1.5A rms max;
@200 - 240V a-c: 0.75A rms max
3.3V Model:
@100 - 120V a-c: 1.1A rms max;
@200 - 240V a-c: 0.55A rms max.
Initial Turn-on Surge: (cold start 25 °C, first surge
only, not including the current flow into the EMI fil-
ter):
@100V a-c rms, 14A typ.,
@200V a-c rms, 28A typ.
Brownout Voltage: 85V a-c, 110V d-c
Switching Frequency: 135KHz typical, PFC boost
converter: 80KHz typical, nominal load
STABILIZATION:
Source Effect:
95-132V a-c or 190-265V a-c:
0.3% typ.; 0.6% max.
3.3V Model 5mV typ., 10mV max.
Load Effect:
12V-48V models: 0.5% typ.; 1.2% max.,
3.3V, 5V models: 1.5% typ.; 2% max.
Temperature Effect, Range -10
o
to 50
o
C:
0.5% typ.; 1.0% max.
Combined Effect (source, load, temperature):
0.9% typ., 1.8% max.
Time Effect (drift): (1/2 to 8 hr. at 25°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 <2 ms (load change t
r
or t
f
equal to or greater
than 50
µ
sec).
START-UP TIME:
400 ms. typ., 500 ms. max. (100V a-c),
200 ms. typ., 300 ms. max. (240V a-c),
ACCEPTABLE LOAD CAPACITANCE:
(Start-up
time is affected.)
10,000
µ
F max.
HOLDUP TIME:
35 ms. typ., 20 ms. min.
DIELECTRIC STRENGTH:
(at 15 to 35°C ambient,
10 to 85% relative humidity):
Between input and output: 3KV a-c for one minute,
cutout current 10ma.
Between input and ground: 2KV a-c for one minute,
cutout current 10ma.
Between output and ground: 500V a-c for one min-
ute, cutout current 20ma.
INSULATION RESISTANCE:
Between input and
ground, output and ground, input and output, ±RC ter-
minals and input, ±RC terminals and output: 100
Megohms min. (500V d-c).
LEAKAGE CURRENT:
0.13mA typ, 0.19mA max at 120V a-c and 60 Hz
(operating in conformance with Den-An).
0.30mA typ, 0.45mA max at 240V d-c and 60 Hz
(operating in conformance with IEC 950 and
UL1950).
SAFETY:
Certified to UL 60950-1, 1st Edition, 2007-10-
31 (Information Technology Equipment - Safety - Part 1:
General Requirements) and CSA C22.2 No. 60950-1-03,
1st Edition, 2006-07 (Information Technology Equipment -
Safety - Part 1: General Requirements). Units are CE
marked per the Low Voltage Directive (LVD), 2006/95/EC
(LVD) and 2004/108/EC (EMC). [The standards do not
apply with either DC input operation or with a-c input fre-
quency above 66Hz.]
RoHS COMPLIANCE:
RoHS 5 of 6 compliant to EU
directive 2011/65/EU if used as component within tele-
communication systems.
COOLING:
Natural convection for 3.3V model; 5-48V
models use forced convection, ball-bearing fans, life
expectancy 50,000+ hours. Natural convection can be
used for 5-48V models if the load does not exceed the lim-
its specified in Figure 4). Simply disconnect the fan and
install jumper J1 (see Figure 7); the alarm signals
described above are disabled and VDC ON lights red;
overvoltage and open sense line conditions still force unit
shutdown. Contact Kepco’s Application Engineering for
full-featured natural convection-cooled units.
EMI:
Designed to meet FCC Class B (100-120V a-c)
and VDE 0871 Class B (220-240V a-c).
VIBRATION:
(non-operating, one hour on each one of
the three axes):
5-10 Hz, 10 mm amplitude;
10-55 Hz, 2g acceleration.
