EA Elektro-Automatik Laboratory power supply, adjustable EA

The compact design and favorable price-performance ratio characterize the laboratory power supplies of the EA-PS 2000B series. In addition to overvoltage protection, which safeguards connected devices from excessive voltage, there is now also a selectable overcurrent protection feature. This shuts off the output when a threshold, adjustable from 0 to 110% of the nominal current, is reached, protecting the device from overcurrent and potential damage in case of a fault.

The set values for current and voltage adjust mutually to ensure that the maximum power, calculated as P = U x I, is not exceeded. This allows for operation with either a high output voltage or a high output current.

Through the built-in USB interface, the device can be monitored and controlled remotely. An optional license extension allows for the serial control of multiple devices. This makes the units particularly suitable for educational institutions, industrial and system applications, workshops and development, laboratories, and testing institutes.
