Manufactured By: AMETEK Programmable Power

ReFlex Power™ is a high density, modular programmable power system providing DC, AC and electronic load assets all under control of a single controller. It provides a reconfigurable, flexible platform ideal for ATE and production test environments where RFP™ can provide programmable stimulus and bias power as well as programmable loads for the device(s) under test. The EIA 4U high RFP™ mainframe can hold up to 12 single-slot modules or combinations of single, dual and triple slot wide modules to configure (or reconfigure) the system for the particular requirements at hand. The mainframe can support up to 6 kW of output power.

Up to 8 mainframes, potentially up to 95 modules, can be controlled via a single controller. The controller communicates to the individual modules via a high speed proprietary bus protocol, providing very high data rates and a high degree of deterministic control. The RFP™ controller communicates to the host controller via an Ethernet LAN connection designed to be compliant with the LAN Extension for Instrumentation ( ™ ) standard, assuring interoperability and ease of integration. RFP™ system modules can be combined via the controller, permitting the creation of “virtual assets” with the voltage/current combinations required for a particular test regime. Creating “virtual assets” reduces the “logistical tail” and total cost of ownership.

The mainframe provides internal power distribution, cabling, I/O and power connection and rack mounting for 12-asset slots. The mainframe also supplies the signal and control bus fabric supporting multi-module series/parallel operation, complex triggering, fault I/O and inter-mainframe control infrastructure.
