Modular Power
Elgar ReFlex Power™ (RFP™) Module Series — AC/DC Sources + Loads in One Platform
ReFlex Power™ (RFP™) is a high-density modular programmable power system that combines DC power, AC power, and electronic load modules under a single controller. It’s a reconfigurable platform built for ATE and production test, enabling engineers to build “virtual assets” and scale control across multiple mainframes.
Why Modular Power?
Build the exact power you need—now and later
ReFlex Power™ is designed as a truly modular system so teams can configure and reconfigure AC sources, DC supplies, and loads to match changing test needs without rebuilding the rack each time.
One controller, many assets
The platform supports 100% digital system control and can control up to 95 assets across 8 mainframes, helping standardise automation across labs and production lines.
Key Benefits
What you gain with Modular Power (RFP™):
- Programmable AC/DC/Loads in a single modular system

Frequently Asked Questions
-
What is a modular power system?
A modular power system is a configurable platform where multiple modules—such as AC sources, DC supplies, and electronic loads—operate under one control architecture to support flexible test setups.
-
How does ReFlex Power™ differ from traditional power supplies?
Unlike fixed-output supplies, ReFlex Power™ (RFP™) lets you combine modules into “virtual assets” and reconfigure system behavior through the controller—helping you adapt quickly as test requirements change.
-
What is a “virtual asset” in the RFP™ system?
A virtual asset is a user-defined combination of RFP modules that behaves like a single programmable source or load, created by the controller to meet a specific voltage/current requirement for a test regime.
-
Can Modular Power support both AC and DC testing?
Yes. The Modular Power category explicitly includes AC power modules, DC power modules, and DC load modules, enabling both AC and DC test configurations within the same modular platform.
-
How scalable is ReFlex Power™?
RFP can scale control up to 95 assets across 8 mainframes using a single controller, supporting expansion across test stations and production lines.
-
What types of power modules are available in the RFP™ Series?
The Modular Power category includes these module types:
- RFP AC Power module (AC output module) (140–280V, up to 875VA).
- RFP DC High Power module (DC output) (33–450V, up to 1000W).
- RFP DC Low Power module (DC output) (16–65V, up to 330W).
- RFP DC Load module (DC electronic load) RFP DC Load modules (up to 500V, 750W).
- RFP Controller (Ethernet-enabled).
- RFP Chassis (12-slot universal input mainframe).
-
Can modular power systems be integrated into automated test environments (ATE)?
Yes. RFP is positioned for ATE and production test, using a controller with Ethernet LAN host communication and LXI-aligned design for integration and interoperability.
-
How does the RFP controller communicate with modules and the host?
The controller uses a high-speed proprietary bus for deterministic module communication and connects to the host using Ethernet LAN for test automation integration.
-
What makes RFP ideal for dynamic test setups?
RFP supports module combining and series/parallel style configuration via the control infrastructure, enabling fast test reconfiguration and reuse of assets across multiple DUT programs.
-
What power modules are available in the ReFlex Power™ (RFP™) series?
The Modular Power category includes RFP AC Power, RFP DC High Power, RFP DC Low Power, RFP DC Load, plus the RFP Chassis and RFP Controller for system integration.
-
How are electronic loads used in modular systems?
Electronic loads help simulate real operating conditions by drawing controlled current/voltage/power from the DUT; in RFP, the DC Load module supports programmable load profiles useful for converter, supply, and battery test.
-
What are the input and output capabilities of the RFP Chassis?
The RFP chassis supports 115–400 V input, provides a 12-slot 4U mainframe, and supports up to 6 kW output power per mainframe depending on configuration.
-
