Programmable bidirectional DC power supplies

General

The microprocessor-controlled, bidirectional power supplies of series EA-PSB 9000 3U incorporate two de-

vices in one: a power supply (source) and an electronic load (sink) with energy recovery. Based on these two

features the devices oer the functionality of two-quadrants operation as standard. The internal electron-

ic load achieves a high voltage dynamics by discharging the unavoidable capacitance on the DC terminal. For

a connected source, the devices are full electronic loads with energy recovery feature, such as the devices

from series EA-ELR 9000.

In source operation mode the device becomes a exible, autoranging power supply like those of series EA-

PSI 9000. It incorporates the advantages of both device types into one and at the same time it eliminates

the disadvantages of separate units regarding weight, space requirement, costs and eort to implement

them into custom test software.

Programmable bidirectional DC power supplies EA-PSB 9000 2.5 kW AC supply All models are provided with an active Power Factor Correction (PFC) circuit and are designed for operation on a single phase supply with 230 V (±15%). During load operation, the device regenerates the consumed DC energy and feeds it back into the local power network. This helps saving a lot of energy costs.

Programmable bidirectional DC power supplies EA-PSB 9000 2.5 kW Display and control panel Set values and actual values of input & output voltage / current / power are clearly represented on the graphic display. The color TFT screen is touch sensitive and can be intuitively used to control all functions of the device with just a finger tip. Set values of voltage, current, power or resistance can be adjusted using the rotary knobs or entered directly via a numeric pad.

Programmable bidirectional DC power supplies EA-PSB 9000 2.5 kW Additionally to the standard functions, which are all based upon a so-called arbitrary generator, this generator is accessible for the creation and execution of complex sets of function runs, separated into up to 99 sequence points. Those can be used for testing purposes in development and production.
