Page 21: Chapter 4 Power Supply Description
All the power outputs from the onboard DC/DC converter subsystems are filtered using power ferrites reducing emissions in the frequency range of 30 to 150MHz. The ACS-5151 will exceed the requirements of the EC low voltage directives for CE compliance. An input filter specially dimensioned for the ACS-5151 power supply ensures compatibility with EN-55022 class B or MIL-STD-461 requirements for conducted and radiated emissions. -
Page 22: Dc/Dc Step Down Converter Module
(Refer to the LED Description for location information.) Current Limit To protect the ACS-5151 against fault or error conditions the +5V DC/DC converter circuit is equipped with a current limiter to provide continuous overload protection. After reaching the current limit point (typically 5 - 10% exceeding the rated maximum current), the output voltage will vary between the rated nominal output and zero depending on the level of overload. -
