Description
The RAC45-xxG/OF series are low cost, 4”x2” AC/DC power supplies with universal inputs
(90-264VAC) and fully protected and isolated DC outputs in the range of 12V up to 48V. The converters
are offered in open frame (/OF) version. The outputs are trimmable to compensate for cable losses and
are short circuit and overload protected. The converters work over a wide temperature range of -25°C
to +60°C (with derating), are UL60950, EN60950 and CE certified and comply with Class B EMC limits.
The RAC45-G series come with a three year warranty.
