INPUT SURGE: Cold start:

100V a-c input, 100% load: 15A typ., 30.0A max.

240V a-c input, 100% load: 30A typ., 60.0A max.

LEAKAGE CURRENT: Cold start:

100V a-c and 60 Hz (single pole switching):

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: 0.6 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)

2.0% 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. Recovery time is

1mS maximum.

HOLD UP TIME: Upon input interruption the output is

maintained for 160 milliseconds typical with 240 Va-c input

voltage, and for 20 milliseconds typical with 100 Va-c input

voltage. The condition for output load is 100%.

START UP TIME:

100 Va-c:

650mS max., 350mS typ.

240 Va-c:

320mS max., 130mS 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: 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):

capacitor 500pF, series resistor 100 Ohms, operating, nor-

mal operation)

SURGE WITHSTAND: 1.2x50µs 3KV pulse (operat-

ing, 100 Ohm internal series resistor).

INCOMING NOISE: 1 µs, 2 KV pulse, 50-60Hz, with

50 Ohm termination, input to input, input to chassis, less

than five minutes, operating. normal operation.
