 Please refer to the part number structure for additional options and complete ordering part numbers.

 All speciﬁ cations are at nominal line voltage and full load, +25°C. unless otherwise noted. See

detailed speciﬁ cations.

Output capacitors are 1 μF ceramic in parallel with 10 μF electrolytic. Input cap is 22 μF, low ESR.

These I/O caps are necessary for our test equipment and may not be needed for your application.

Nominal Output Voltage

In tenths of a volt

UEI30 - Q48-050

Input Voltage Range:

Q12 = 9-36V

Q48 = 18-75V

RoHS-6 hazardous substance compliance

(does not claim EU RoHS exemption 7b–lead in solder)

-N

On/Off Control Logic:

P = Positive

N = Negative

Positive “P” logic is standard for Q12 models and optional special

order for Q48 models. Negative “N” logic is standard for Q48 models

and optional special order for Q12 models.
