• Description: AC to DC Power Supply, 20V Output
• Manufacturer: Acopian Power Supplies

DC-DC Converters
Mini Encapsulated - with screw terminals
REGULATED
single & dual tracking outputs
These DC-DC Converters have the versatility to be used
in a broad range of applications. Threaded mounting
holes permit them to be mounted to a chassis, cabinet
wall or bracket, or they may be used on a test bench or
tabletop. Screw terminals provide easy connection
without sockets or soldering.
SPECIFICATIONS
Input Voltage: Nominal voltage ±10%.
Input Reflected Ripple: 1% E
Output Ripple (@25 MHz bandwidth):
Output Voltage Setting: Outputs are factory preset to
within ±1% of the nominal output voltage.
T/C terminal: For single output models, 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. For dual
output models, the T/C terminal is the output common.
Polarity: The output of single output models may be
connected in either polarity. Dual output models have a
positive/common/negative output terminal configuration.
Transient Response (NL-FL): 50 microseconds.
Overload/Short Circuit Protection: Electronic current
limiting with automatic recovery. All models have thermal
protection with automatic reset.
Input/Output Isolation:
Switching Frequency: 20 kHz minimum.
Temperature Coefficient: 0.02%/°C (Typical).
Ambient Operating Temperature: – 20 to +71°C.
Storage Temperature: – 40 to +85°C.
Humidity: 20% to 80% R.H. (non-condensing).
Case Size: EBC-10.
Mounting: Threaded mounting holes permit mounting to
a chassis, cabinet wall or bracket, or they may be used
on a test bench or tabletop. When wall-mounting or DIN
rail mounting is desired, use accessory Mounting Kits on
page 19.

(max.)
Input/output isolation prevents ground loops, and permits
the use of inputs of either polarity; outputs of single
output models may be used in either polarity and floated
up to 500 volts above the input. Short circuit and thermal
protection, and rugged encapsulated construction,
assure years of reliable service.
