Table 1-1. Specifications
INPUT:
105-125Vac, single phase, 50-400Hz.
OUTPUT:
0-25Vdc, 0-400mA.
LOAD REGULATION:
Less than 0.01% plus ImV for a full load to no
load change in output current.
LINE REGULATION:
Less than 0.01% plus 4mV for any line voltage
change within the input rating.
RIPPLE AND NOISE:
Less than 200|j.Vnns/lmV p-p (dc to 20MHz).
TEMPERATURE RANGES:
Operating: 0 to 55°C. Storage: -40 to +85°C.
TEMPERATURE COEFFICIENT:
Less than 0.02% plus ImV per degree Centi
grade.
STABILITY:
Less than 0.10% plus 5mV total drift for 8 hours
after an initial warm-up time of 30 minutes at
constant ambient, constant line voltage, and
constant load.
INTERNAL IMPEDANCE AS A CONSTANT VOLT
AGE SOURCE:
Less than 0.03 ohms from dc to IkHz.
Less than 0.5 ohms from IkHz to lOOkHz.
Less than 3.0 ohms from lOOkHz to IMHz.
TRANSIENT RECOVERY TIME:
Less than 50[j.sec for output recovery to within
lOmV following a full load current change in the
output.
OVERLOAD PROTECTION:
A fixed current limiting circuit protects the
power supply for all overloads including a direct
short placed across the output terminals in con
stant voltage operation.
METER:
The front panel meter can be used as either a
0-30V voltmeter or as a 0-500mA ammeter.
OUTPUT CONTROLS:
Coarse and fine voltage controls set desired
output voltage. Meter switch selects voltage or
current.
OUTPUT TERMINALS:
Three "five-way" output posts are provided on
the front panel All power supply output terminals
are isolated from the chassis and either the posi
tive or negative terminal may be connected to the
chassis through a separate ground terminal located
on the output terminal strip.
COOLING:
Convection cooling is employed. The supply
has no moving parts.
SIZE:
5i"/13,34cm W x 3i"/8,26cm H x 7"/l7„78cm D.
Using a Rack Mounting Kit, three units can be
mounted side by side in a standard 19" relay rack.
■WEIGHT:
5.25 lbs./2,38 kg. net, 71bs./3,17kg. shipping.
FINISH: Dark Cray
POWER CORD:
A three-wire, five-foot power cord is provided
with each unit.
