Mini Encapsulated - PC Board Mounting (6-Day Power Supply)
Switching Regulated Power Supplies

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


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% (5 and 6 Vdc out models, ± 0.1%)

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.


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).
