OPERATING TEMPERATURE: -10 to 50°C (start up -
20 to -10°C). See the derating, Figure 1. Do not allow the
power supply to become dust covered because that will
decrease the cooling efficiency of the unit and cause insu-
lation to deteriorate.
STORAGE TEMPERATURE: -30°C to + 75°C.
COOLING: Natural convection.
ORIENTATION: Vertical or horizontal.
HUMIDITY: 10% to 95% RH, operating and storage,
noncondensing, wet bulb temperature < or = 35°C.
DIELECTRIC STRENGTH: (at 15 to 35°C ambient, 10
to 85% relative humidity, cutout current 20 ma):
Between input and output terminals:
3.0 KV a-c for one minute.
Between input terminals and ground:
2 KV a-c for one minute.
Between output terminals and ground:
500V a-c for one minute.
INSULATION RESISTANCE: Between input and out-
put, input and ground, output and ground: 100
megohms minimum (500V d-c, 15 to 35°C ambi-
ent, 10 to 85% relative humidity).
VIBRATION: Three axes, one hour each, sweep time 10
min:, nonoperating:
5-10 Hz., 10 mm amplitude.
10-200 Hz., 2G (19.6m/s
2
).
SHOCK: (non-operating, one-half sinusoidal pulse, three
shocks to each axis):
Acceleration: 60G (588m/s 2 ),
Duration: 11mS +5mS
EMC - EMISSIONS:
Radiated Noise 30MHZ to 1GHz: FCC Class B,
VCCI-B, EN55011-B, EN55022-B
Conducted Noise 0.15MHz to 30MHz:
FCC Class B, VCCI-B, EN55011-B, EN55022-B
Input Harmonics (on AC Mains) 0 to 2kHz:

Electrical Fast Transient/Burst (EFT):
EN 61000-4-4 Level 3, Normal operation.
Surge: EN 61000-4-5 Level 4, no damage.
Conducted Noise:
EN 61000-4-6 Level 3, Normal operation.
Power Frequency Magnetic Field:
EN 61000-4-8 Level 4, Normal operation.

SAFETY: All units designed to meet EN 60950 (U.S. UL
60950 3rd Ed.; Canada: CAN/CSA-22.2 No. 60950-00 3rd
Ed. (ambient temp. 50°C)". RKW 100W units are CE
marked per the Low Voltage Directive (LVD), EN60950.
[The standards do not apply with DC input operation.]
WEIGHT: 21 oz. (600 grams) max.
WARRANTY: One year.
IV — INSTALLATION
MOUNTING THE POWER SUPPLY: Refer to Fig-
ures 4 and 5. The unit may be mounted on one mounting
surface. Note the restrictions for maximum penetration of
mounting screws. The air surrounding the power supply
must not exceed the ambient values given in the graph in
Figure 1.
CONNECTIONS: Connect the load to the power supply
as shown in Figure 3A. B, or C. The unit is shipped with
shorting links in place for Local sensing. The AC input
power is applied via the terminal block. Make sure to con-
nect the AC input Neutral, Line and Ground wires to the
respective terminals of the terminal block (see Figure 2).
Sensing (either Local or Remote) MUST be used.
LOCAL/REMOTE SENSING: Figure 3 shows proper
connection of multiple loads using either remote or local
sensing. If local or remote sensing is not configured,
the unit will not work properly. The unit is shipped with
shorting links in place for Local sensing. For remote sens-
ing, remove the shorting links and connect the +S and –S
terminals to the load. Remote sensing compensation is up
to 0.4V per load wire (0.15V for RKW 3.3-25K, 0.25V for
RKW 5-20K). Transient recovery specs may not be met
when remote sensing is used. If oscillations set off over-
voltage protection, install one electrolytic capacitor (470
µF
min) between +S and + and one between – and –S termi-
nals.
