Aimtec Inc. has introduced the AM20EW-Z series of 20W DC/DC converters with an ultrawide 4:1 input range of 9-36Vdc and 18-75Vdc. Targeting a variety of applications, the 2-inch x 1-inch converters are suitable for data communications equipment, distributed power systems, telecommunications equipment, mixed analog/digital subsystems, process/industrial control equipment, computer peripheral systems and industrial robotic systems.

Highly regulated (0.5 percent) and isolated (1,600Vdc) single- and dual-output ranges of 3.3V, 5V, 12V, 15V, 5V, 12V and 15Vdc are fully protected against short circuit, overvoltage and over current. In addition, totally isolated outputs eliminate efficiency penalties and output interaction problems, as well as allow reverse polarity of the output with reference to the input, Aimtec said.

Other features include output trim function (10 percent) and remote ON/OFF control, making these converters suitable for applications where conservation of the device's power consumption is required and/or there is a need for the power supplies to switch ON and OFF in a specific sequence, within an operating temperature range of -40C to +66C and to +85C with derating.

The AM20EW-Z series complies with the 60950-1 safety standard, as well as EMC standards including EN55022 for emissions and EN61000 for immunity. Each of the 14 models use 100 percent RoHS-compliant materials.

Pricing starts at $32.08 for 1,000+pieces. Samples are available from stock and can be ordered immediately.
