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 minute,
cutout current 20ma.
INSULATION RESISTANCE:
ground, output and ground, input and output, ±RC ter-
minals and input, ±RC terminals and output: 100
Megohms min. (500V d-c).
LEAKAGE CURRENT:
0.29mA typ, 0.45mA max at 100V a-c, 60 Hz (operat-
ing in conformance with Den-An).
0.40mA typ, 0.65mA max at 240V d-c and 60 Hz
(operating in conformance with IEC 950 and
UL1950).
SAFETY: Designed to meet EN 60950:2001 Assistance
for DEN-AN. U.S. UL 60950 First Edition.; Canada: CSA-
22.2 No.60950-1. Units are CE marked per the Low Volt-
age Directive (LVD), EN60950 73/23/EEC AND 93/68/
EEC. [The standards do not apply with DC input operation.]
COOLING: All models use forced convection, ball-bear-
ing fans, life expectancy 50,000+ hours. Natural convection
can be used if the load does not exceed 60% of max. (see
Figure 4). Simply disconnect the fan and install jumper J1
(see Figure 5); the alarm signals described above are dis-
abled and VDC ON lights red; overvoltage and open sense
line conditions still force unit shutdown. Contact Kepco's
Application Engineering for full-featured natural convec-
tion-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.
SHOCK: (non-operating, one-half sinusoidal pulse, three
shocks to each axis):
Acceleration: 20g,
Duration: 11mS +5mS
OPERATING TEMPERATURE: See Figure 5.
STORAGE TEMPERATURE: -40
