INPUT SURGE:
Cold start:
100V a-c input, 100% load: 15A typ, 19.5A max.
240V a-c input, 100% load: 30A typ., 41A max.
LEAKAGE CURRENT:
Cold start:
100V a-c and 60 Hz (single pole switching):
0.75mA max, 0.2mA typ
100V a-c and 60 Hz (single pole switching in confor-
mance to UL 1950/IEC 950):
0.75mA max, 0.30mA typ
POWER FACTOR:
100V a-c: 0.6 typ.
240V a-c: 0.45 typ.
OUTPUT CHARACTERISTICS:
SOURCE EFFECT:
(85 to 265 Va-c)
0.4% max.
LOAD EFFECT:
measured at sensing terminals (0% -
100% load change)
0.8% max.
TEMPERATURE EFFECT:
(-10 to 50°C)
1.0% max.
TIME EFFECT OR DRIFT:
(1/2 to 8 hr. at 25°C)
0.4% max.
TRANSIENT RECOVERY:
A step load change from
50% to 100% of rated load in 50 microseconds or more
produces no more than 4% output voltage excursion.
Temperature range from -10 to 50°C.
HOLD UP TIME:
Upon input interruption the output is
maintained for 150 milliseconds typical with 240 Va-c
input voltage, and for 13 milliseconds typical with 100 Va-
c input voltage. The condition for output load is 100%.
START UP TIME:
JBW 5V and 12V:
100 Va-c: 200mS max., 25mS typ.
240 Va-c: 100mS max., 25mS typ.
JBW 15V and 24V:
100 Va-c: 200mS max., 40mS typ.
240 Va-c: 100mS max., 40mS typ.
OVERVOLTAGE PROTECTION:
Fixed, factory set.
See Table 1. The overvoltage circuit is set by Zener diode
clamp, latching could occur.
OVERCURRENT:
Square type, output voltage returns
to rated level upon removal of cause of malfunction (long
term overcurrent could damage unit).
ENVIRONMENTAL CHARACTERISTICS
OPERATING TEMPERATURE:
-10 to 60°C (start up
-20 to -10°C). See the derating, Figure 1.
STORAGE TEMPERATURE:
-30°C to + 75°C.
COOLING:
Natural convection. 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.
ORIENTATION:
Vertical or horizontal (see Figure 2).
HUMIDITY:
20% to 90% relative humidity, operating
and storage, noncondensing, wet bulb temperature < or =
35°C.
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
) acceleration
SHOCK:
Three axes, 60G (588m/s
2
), 11 mS ±5mSec
pulse duration, three shocks each axis, nonoperating, 1/2
sine pulse.
GENERAL CHARACTERISTICS
WITHSTANDING VOLTAGE:
(at 5 to 35°C ambient,
45 to 85% relative humidity, cutout current 10 mA):
Between input and output terminals:
3.0 KV a-c for 1 minute.
Between input and output or chassis:
2000V a-c for 1 minute.
Between output terminals and chassis:
500V a-c for 1 minute.
INSULATION RESISTANCE:
Between input and out-
put, input and chassis, output and chassis: 100 megohms
minimum (500V d-c, 5 to 35°C ambient, 45 to 85% relative
humidity)
SAFETY:
All units designed to meet UL 1950-3, CSA

capacitor 500pF, series resistor 100 Ohms).
SURGE WITHSTAND:
1.2x50µs 3KV pulse input to
input, input to chassis (operating, normal operation, 100
Ohm internal series resistor).
INCOMING NOISE:
