EA Conventional DC Power Supplies
Rackmount autoranging programmable power supplies
The EA PS and PSI programmable power supply series range in power from 1000W devices up to 30kW in a single chassis. High power density PSI units can paralleled easily up to 1,92MW in output power, with up to 2000 VDC. All EA Elektro-Automatik DC programmable power supplies feature True Autoranging which automatically adjusts current higher at lower voltages, and vice versa, to maintain full power across wider testing requirements. Simply put, autoranging allows you to test more with one device.
The PSI series conventional Programmable DC power supply features 5″ TFT Gorilla® Glass touchscreen display for intuitive control and test setup. The easy-to-use interface enables you to configure and test quickly. EA PSI programmable power supplies come standard with a built-in function generator capable of creating arbitrary waveforms, a field-swappable digital interface module and included test routines for battery test, fuel cell simulation, PV solar array simulation with MPP tracking, and much more.

The Gold Standard – True Autoranging
All EA PSI and most PS offer True Autoranging which means full power is maintained over a wider testing range. Autoranging power supplies demonstrate a more dynamic power profile raising current as voltage drops and vice versa. With this capability, autoranging allows engineers to test more program requirements with just one device. While many typical autoranging power supplies start to lose power before dropping to just 50% of their rated output voltage, EA Elektro-Automatik’s True Autoranging provides full power all the way down to 33% of the rated output voltage.
- Save space and budget
- No need to oversize the supply power
- One power supply can test more programs
- Future-proof for new tests that arise
Built-in Function Generator
Then need for programmable DC power supplies to deliver output voltage or current with a programmed waveform other than a straight-line DC signal is now a requirement. EA’s built-in function generator includes options for many typical waveforms such as sine, triangle, rectangle, and trapezoid, as well as custom arbitrary waveforms. Additionally, configuration tools for ramping, UI and IU tables, as well as simulations for fuel cells and photovoltaics with MPP tracking are included.
Swappable Anybus Control Modules
EA “Anybus” modules are easily installed and swapped by the user and can be changed with just a few minutes and a screwdriver when a different communication protocol is required. You have many choices for computer or remote control, such as Ethernet, USB, EtherCAT, ProfiNET, ProfiBUS, CAN, CANOpen, Modbus, Devicenet and RS232 interfaces, to name a few.
