“The EN specification does not require power factor correction; it sets limits on harmonic currents. The FlatPAC-EN solution, unlike PFC, provides passive attenuation, is simple, robust, reliable and inexpensive.”

FlatPAC EN Powers a Ruggedized
Industrial Automation Application


Automation is the use of control systems (such as numerical control, programmable logic control, and other industrial control systems), in concert with other applications of information technology (such as computer-aided technologies [CAD, CAM, CAx]), to control industrial machinery and processes, reducing the need for human intervention. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the physical requirements of work, automation greatly reduces the need for human sensory and mental requirements as well. Processes and systems can also be automated.

Our customer is a provider of ― among other products and services ― vertically integrated electronics manufacturing solutions. This application uses a ruggedized embedded computer for an industrial automation system, which is ultimately used as part of a protection system for a nuclear power plant.

FlatPAC-EN is a rugged, EN-compliant, autoranging AC-DC switcher that meets MIL-STD-810E requirements for vibration. One additional important requirement for the power solution was to satisfy the harmonic current provisions of EN61000-3-2. For the last few years, compliance to EN61000-3-2 has been required in order to do business within the European Economic Community. FlatPAC does, in fact , comply with harmonic current limits per EN61000-3-2, and further, also ― valuable for this application ― meets Electrical Fast Transient/Burst per EN61000-4-4 and Surge Immunity per EN61000-4-4. For conducted EMI, the FlatPAC also conforms with FCC Class A and B and EN55022, Class A and B.
