ACRX Series

Eurofeedback has developed a range of high voltage capacitor charging power supplies with output voltage from 10 kV to 50 kV and output power from 6 kJ/s to 15kJ/s.

The power supplies use the “H bridge” topology. The commutation looses are very low, so the efficiency is greater than 85%.

By design, the power supplies are protected from over currents, over voltages and no load fault conditions. The fan fault is associated with a tempterature fault. All power supplies are equipped with an interlock, located on the rear panel.

Interfaces

Human-Machine Interface

The power supplies can be operated in remote mode (0-10V program and monitor). The analog programming, analog monitoring, faults and controls are available on the 25 pins Sub-D connector. On the front panel, lights are available to indicate the power supplies status.

Instrumented

In the instrumented version, output voltage can be adjusted on the front panel. The screen displays voltage/current programming and monitoring. If a fault occurs, it will be displayed on the screen.

RS232 / Ethernet

HV-Capacitor-montage-RS232-Ethernet

 

Ethernet/RS232 communications are available as an option. An 9 pins Sub-D connector and a RJ45 connector are located on the rear panel. It is easy to connect the computer with our demonstration software and to drive the power supply. 

Optical Fibers

HV-Capacitor-montage-Fibre

 

The optical fibers is useful to drive the power supplies in ensuring the data transmission in a perturbated environmenent. Moreover, the electrical insulation is warranted between the power supplies and the control station.

Mechanical

dimensions_800

The power supplies are integrated inside a standard 19" inches width rack with a 5U height (222mm/ 8.74 in). The depth is included between 510 mm and 600 mm, depending on the input voltage and the power output.

cable_ht_750

 

All power supplies are delivered with a HV plug and a high voltage cable of 3 meters length (9.8ft).
