Digital High-performance Programmable Power Supply Controller.

This breakthrough power supply controller allows converting your programmable power supply unit or amplifier in a state-of the-art power converter unit with built-in Web-ServerWaveform Generation and Oscilloscope functions.

This fan-less unit comes together with a 0-FLUCS current transducer by CAEN ELS and with voltage sensing terminals, with current measuring ranges up to 1.000 A and 200 V.

Any power converter within these ratings can be connected to the controller and its current and voltage values are monitored and stabilized by the internal configurable digital control loop (on a FPGA) so that any load conditions can be easily fit in order to obtain the desired response.

The digital current control loop makes the connection and configuration of the power supply to any load quick and simple.

This controller will transform any power converter to a ppm-level stability power unit, with negligible line and load regulation values and will greatly improve the accuracy.

The programmable power supply connected to the REGUL8OR can be driven by multiple interfaces: a precision fast DAC (± 5 V or ± 10 V) or a 4-20 mA loop driver.

Obtain outstanding long-term stability, great accuracy, low temperature coefficient, excellent load and line regulation.

The 10/100/1000 Mbit Ethernet connection over TCP-IP or UDP allows controlling the power converter in a very simple and reliable manner and also accessing the embedded web-server.

The embedded Web-Server allows running pre-loaded or custom waveforms at 100 ksps and monitor and record the response of different values – e.g. output current, voltage, etc. – at 100 ksps per channel simultaneously (soft-oscilloscope).
