High Voltage Power Supplies Series EA-HV 9000

The power supplies of the series EA-HV 9000 are frequency modulated resonance converters. The push-to-push switching frequencies are up to 200kHz in the power range of 500 to 2000W. Because the trapezoid shaped voltage is switched when passing zero the efficiency of the switching stage is nearly 99%. This modern concept in connection with multi regulation loops allows the construction of precise high voltage systems up to 100kV with outstanding regulation performances. The mains input is 90...264V/50-60Hz with an active power factor correction.

Function
The units are available as 19"-rack- (Suffix "R") or bench- (Suffix "T") versions. Voltage and current are adjusted with 10-turn potentiometers, the values can be preset in stand-by mode and are displayed on digital meters. The operation modes are indicated by LED's. The output voltage and current can be externally set by means of an external voltage of 0...10V for 0...rated value (SPS-control). The two external monitor outputs (V & I) provide each an output voltage of 0...10V for 0...rated value. In connection with the IEEE.2 interface practically all systems applications are possible. An Interlock loop is available on the programming terminal.

The units of the series EA-HV 9000 are flashover- and continuous short circuit proof, whereas voltage and current are still adjustable from 0...100%. On a large fall back of the output voltage the unit is switched off for a short time and than automatically starting slowly again from 0V to the preset voltage. The energy reaching the output is therefore reduced to a minimum. So applications with tubes, plasma-gas-decharging-processes and capacitor charging are possible.

The output ripple is less than 5x10-4 pp on max. rated output current. The ripple depends on the actual output current. On 30% of the rated output current (600 Watts output power) the ripple is less than 1x10-4 pp.

For special applications a unit with extreme low ripple (<0,01% pp) is available.
