• Manufacturer: Acopian Power Supplies

single output
Mini Encapsulated
LINEAR REGULATED
AC-DC
Conserve space with mini-modules as small as 2.3˝ x
1.8˝ x 1.0˝. Models with outputs ranging from 1 to 75
volts, and from 30 mA to 2.5 amps are available. All
feature excellent regulation and ripple parameters, and
are short circuit protected.
STANDARD FEATURES
SPECIFICATIONS
Input Voltage: 105-125 VAC, 47 to 420 Hz, single phase.
Output Voltage Setting: Output is factory preset to
within ±2% (1 to 9 volt models) or ±1% (10 to 75 volt
models) of the nominal output voltage.
T/C terminal (Output Voltage Trim Adjustment):The
T/C terminal can be used to trim the output more
precisely to the nominal voltage rating by connecting an
external resistor from the T/C terminal to either the + or –
terminal.
Polarity: Output is floating. Either positive or negative
terminal may be grounded.
Ambient Operating Temperature: –20 to +71°C.
No derating required.
Storage Temperature: –55 to +85°C.
Temperature Coefficient: From 9 to 75 volts, typically
0.015%/°C; 1 to 8 volts, 0.03%/°C.
Impedance: 0.07 ohms at 1 kHz and 0.2 ohms at
10 kHz (approx.).
Weight:
Mounting: May be mounted on printed circuit board or in
socket (see page 11).
OPTIONS
230 Volt Input: All models can be alternately furnished
for operation on an input of 210 to 250 VAC,
47-420 Hz. To order, add suffix “–230” to model number
and $10.00 to price. Requires two additional days.
