Mini Encapsulated - with screw terminals (6-Day Power Supply)
Switching Regulated Power Supplies

AC-DC single output
(accepts either AC or DC input)

SPECIFICATIONS

Input Voltage: 85-130 VAC, 47-420 Hz, single phase, or 120-180 Vdc. DC input may be connected without regard to polarity.

Output Voltage Setting: Output is factory preset to within ±2% (5 to 9 volt models) or ±1% (10 to 48 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.

Load Regulation: ± 0.05%

Line Regulation: ±0.05%

Ambient Operating Temperature: -10 to +71 °C. No derating required through +50 °C.

Storage Temperature: -40 to +85 °C.

Temperature Coefficient: ± 0.02%/ °C (Typical).

Humidity: Maximum of 90% relative, non-condensing.

Overload/Short Circuit Protection: Power foldback with automatic recovery.

Isolation:

Input to output: 1400 Vdc
Input to ground: 1400 Vdc
Output to ground: 400 Vdc

Efficiency: 76% (Typical).

Switching Frequency: 225 kHz (Typical).

Transient Response: Returns to within ± 1% of output setting within 300 uS. Maximum of ± 3% output excursion following a load step change from 50% to 100% of rating.

Holdup Time: 33 mS (Typical, at nominal input voltage with full load).

See Drawing for exact dimensions.

Mounting: Threaded mounting holes permit mounting to a chassis, cabinet wall or bracket, or they may be used on a test bench or tabletop. To mount from the power supply side of the mounting surface, use accessory Mounting Kit EB4A. When DIN rail mounting is desired, use accessory Mounting Kit EB35DIN.
