In principle, the rectified line voltage drives a square wave generator of fixed frequency, whose AC voltage is transformed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated.

Low residual ripple of the produced  output voltage together with a high stability, good regulation dynamics and in the same time  only low stored energy will be achieved due to a high switching frequency.

Design:

• ½19" or 19" table-top case (depending on output voltage and power)
• 19" Rack-adapters for mounting into a 19" rack are available as accessory

Output:

• Output isolation:
  The output is floating. Either the positive or the negative terminal may be connected to earth. Units with nominal voltage up to 350 V are isolated for ±500 V. Units with nominal voltage from 650 V up to 2000 V are isolated for ±2000 V. 
• Output terminals:
  All output terminals are located at the rear side of the unit. 
  Units up to 350 V nominal voltage are equipped with 4mm safety connectors.
  For nominal voltage of 650 V and higher, high voltage connectors with the appropriate dielectric strength are delivered with the power supply.

Technical Data:

• Mains connection:
  

  up to 1400W nominal power:	230 V ±10% 47 Hz to 63 Hz
  for 2800W and higher:	400 V ±10% 47 Hz to 63 Hz, three-phase

• Ambient temperature: 0°C to +40°C

  Residual ripple up to 350W nominal power: for 700W and higher:	<5 x 10-5pp + 50 mVpp <2 x 10-4pp + 200 mVpp
  Recovery time: Voltage control: Curent control:	<1 ms for load changes from 10% to 100% or from 100% to 10% <10 ms for load changes causing an output change of less than 10% of the rated voltage
  Setting time at nominal load:	<300 ms for changes of the output voltage from 10% to 90% or 90% to 10%
  Discharging time constant for output without load:	approx. 2sec. to 10sec., depending on type
  Deviation:  for ±10% mains voltage variation: for no load / full load: over 8 h under constant conditions: within the temperature range:	<± 1 x 10-5 <1 x 10-4 <±1 x 10-4 <±1 x 10-4 / K

The mains voltage is transformed to high voltage potential. Either on the primary side or on the secondary side, a phase cutting circuit with thyristors is installed. The rectified voltage is smoothed by a LC - filter.

Design:

• Depending on Voltage and Power the units are built as single or double 19" cabinets of various height. The side covers are detachable, the rear door is lockable.
• ll cabinets are equipped with fork-lift-compatible pliths and removable crane-eyes.
• Single 19"- cabinets up to  37 HU are also suitable for transportation by fork-lift.
• The cooling is carried out via built-in Fans, the output air is derived (type depending) to the rear side or via the top.
