LEAKAGE CURRENT: Cold start:
100V a-c and 60 Hz (single pole switching) (operating
in conformance with Den-An):
0.75mA max, 0.35mA typ
240V a-c and 60 Hz (single pole switching in confor-
mance to UL 1950/IEC 950):
0.75mA max, 0.50mA typ
POWER FACTOR:
100V a-c: 0.99 typ.
240V a-c: 0.93 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.
COMBINED EFFECT:
2.0% max. (4% typical for overshoot at start-up)
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. Recovery time is
1mS maximum.
HOLD UP TIME: Condition: 100% output load. Upon
input interruption the output is maintained for:
100 Va-c: 20mS typ.
240 Va-c: 20mS typ.
START UP TIME:
100 Va-c, 240 Va-c: 500ms max., 400ms typ.
OVERVOLTAGE PROTECTION: Fixed, factory set.
See Table 1. The overvoltage circuit is set by Zener diode
clamp, latching will 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: 10% 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 (with Y-capacitor removed).
Between input terminals and ground:
2000V a-c for 1 minute.
Between output terminals and ground:
500V a-c for 1 minute.
INSULATION RESISTANCE: Between input and out-
put, input and ground, output and ground: 100 megohms
minimum (500V d-c, 5 to 35°C ambient, 45 to 85% relative
humidity)
SAFETY: All units designed to meet UL 60950, CSA
C22.2,No. 60950-1(C-UL), and TÜV Rheinland EN60950
(ambient temp. 50°C). JBW 50W units are CE marked per
the Low Voltage Directive (LVD), EN60950.
