Example: CP 2540-7R: DC-DC converter, input voltage range 33.6...75 V, each providing 15 V, equipped with R-control
for output 1 and operating ambient temperature of –25...71°C.
Note: All units feature the following auxiliary functions which are not shown in the type designation: input and output filter,
inhibit (primary referenced), sense lines (single, double and triple output modules only) and LED indicators.
Product Marking
Basic type designation, applicable safety approval and recognition marks, CE mark, warnings, pin allocation of input, out-
put and auxiliary functions, Melcher patents and company logo. Label with specific type designation, input voltage range,
nominal output voltage and output current, degree of protection, batch no., serial no. and data code including production
site, modification status and date of production. Confirmation of success fully passed final test.
