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