EA Programmable DC Power Supplies
Benchtop and rackmount autoranging power supply
The programmable DC power supply family from EA range in power from 80W benchtop devices up to 30kW in a single chassis. High power density units can be easily paralleled up to 1,92MW in output, with up to 2000 VDC. All EA Elektro-Automatik DC programmable power supplies feature true Autoranging which automatically offers increased current at lower voltages, enabling a single supply to meet wider test requirements.
The PS and PSI series feature 5 “TFT touch panel display for intuitive control, setup and programming. The intelligent interface allows you to program and test quickly without the need for extensive manual review. This user-friendly touchscreen is a feature not found on competing benchtop supplies.
Most of the PS / I family of programmable dc power supplies come standard with an arbitrary waveform function generator, swappable digital interface control and built-in test routines for battery test, photovoltaic simulation and MPP tracking, to name a few.

Minute PSI Benefits Summary Video
True Autoranging – Advantages for Test
All EA power supplies provide true autoranging giving full power across a larger operating range to test more devices with just one supply. Autoranging enables the power supply to automatically adapt to higher output voltages when there is a smaller current or handle higher currents when there is a lower voltage. EA’s true autoranging can deliver full power down to 33% of rated output voltage.
- Save budget and space
- No oversizing supply
- One supply tests more
- Versatile for future tests
Waveform Function Generator
A common requirement for dc power supplies is to deliver the output voltage or current with a waveform other than a straight-line dc signal. EA’s built-in function generator includes options for sine, triangle, square, and trapezoidal waveforms, as well as custom arbitrary waveforms. In addition, the solution offers configuration tools for ramps, UI and IU tables and simulations for fuel cells and photovoltaics.
Swappable Anybus Remote Control
EA “Anybus” modules are easily installed by the user and can be swapped out with just a few minutes and a screwdriver when different communication protocols are desired. For computer or remote control, you have many choices, such as Ethernet, USB, EtherCAT, ProfiNET, ProfiBUS, CAN, CANOpen, Modbus, Devicenet and RS232 interfaces.
