COMMON POWER SUPPLY SPECIFICATIONS
INPUT VOLTAGE:
105-125 V ac, 47 to 420 Hz, single phase
OUTPUT:
See tables 1 and 2
REGULATION:
0.05% line, 0.05% load
RIPPLE:
0.5 mV rms
OUTPUT VOLTAGE TRIM
ADJUSTMENT:
Output is factory preset to ± 2% (1 to 9 volt
models) or ± 1 1% (10 to 75 volt models) of
nominal output voltage. Out put may be
trimmed to the nominal voltage rating with
an external trim resistor.
POLARITY:
Output is floating. Either positive or
negative terminal may be grounded.
AMBIENT OPERATING
TEMPERATURE:
- 20 to + 711 C. No derating required.
STORAGE TEMPERATURE:
-55 to +85°C
TEMPERATURE COEFFICIENT: From 9 to 75 volts, approximate TC is
015%/°C; 1 to 8 volts, .03%/°C
IMPEDANCE:
0.07 ohms at 1 kHz and 0.2 ohms at 10 kHz
(approx.)
DIMENSIONS:
