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.
EA’s PS and PSI programmable power supply series:
- Include true autoranging to cover a wider operating range of voltage and current while still maintaining full output. This means that a much wider range of test routines can be addressed with a single EA bidirectional DC power supply with autoranging.
- Feature 5″ TFT Gorilla® Glass touchscreen display for intuitive control and test setup. The easy-to-use interface enables you to configure and test quickly.
PSI series conventional Programmable DC power supplies:
- Can parallel easily up to 1,92MW in output power, with up to 2000 VDC.
- 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.
FAQs
A DC programmable power supply has an engineered design that delivers consistent voltage levels. This compares to an AC programmable power supply that not only offers stabilized voltage but also generates and controls AC waveforms.
A DC programmable power supply is the preferred choice when the operator needs a system that is simpler to use than an AC programmable power supply. This supply is also more efficient when an application requires a constant DC voltage and when AC power is not required.
A programmable power supply allows users to digitally program desired system capabilities for greater precision and versatility than an adjustable power supply. An adjustable power supply offers users the ability to make manual adjustments to voltage and/or current using analog knobs or controls. In contrast, a programmable power supply allows users to set and control voltage, current and other parameters using a digital system
A programmable power supply is an electronic device that allows users to digitally enter settings and control voltage, current, and other parameters for precise and automated power output adjustments. The programmable power supply enables tailored and automated power delivery depending on specified application requirements such as electronics testing and research.
A programmable power supply allows users to digitally set and control voltage, current and other parameters for precision and automated adjustments, making it a versatile and flexible tool for electronics testing and research and other applications.
In contrast, a non-programmable power supply offers users the capability to make manual adjustments using analog knobs or controls, and it lacks digital programming options. This manual operation limits its precision, versatility and flexibility.
A regulated power supply is designed to provide a stable and constant voltage or current output and a consistent power level to connected devices or circuits. In contrast, a programmable power supply not only offers regulation but also allows users to digitally set and control voltage, current and other parameters. This digital programming allows more precise and automated adjustments to meet specific application requirements. Both types of power supply provide stable power, but programmable power supplies offer greater versatility and customization through digital programming capabilities.
A programmable power supply is controlled using a digital interface or controls, typically involving the following steps:
- Set the desired voltage, current and other parameters through the device’s built-in touchscreen, keypad or buttons or via a connected computer using compatible software.
- Activate the power supply to provide the configured output.
- Monitor and adjust settings as needed during operation and turn off the power supply when tasks are completed.
An example of a programmable power supply is the EA PS and PSI programmable power supply series that range in power from 1000W devices up to 30kW in a single chassis. Many different programmable power supplies are available, and most design and test engineers find they need equipment that comes with autoranging, a function generator, swappable digital interfaces and built-in test routines.
