Unipolar Pulse Generators SD 151, SD 301, SD 351

up to 35 kW Datasheet SD 151, SD 301, SD 351_012022 (497.52 KB)

In combination with an ADL DC power supply, the pulse generators SD 151 / SD 301 and SD 351 generate unipolar pulses with a reverse pulse for faster discharge of the cathode. In combination with reverse pulses, the extremely fast, fully automatic arc suppression reduces the arc energy by approx.  50 % – in comparison to a pulse generator without reverse pulse (SD 150 / SD 300). The generators work with a fixed frequency of 20 kHz. Thus, with an external signal generator, this frequency can be varied in a range of 1 kHz up to 40 kHz. Up to eight pulse generators can be interconnected for automatic synchronization via control cables. The new electronics contained in SD 151, SD 301 and SD 351 compensate delay times, so that even if the high voltage outputs are connected in parallel, no master oscillator is necessary for exact synchronization.

Accessory: Test Oscillator OT

With the OT 40 the frequency and the pulse off time can be set independently from each other. The perfect values for frequency and pulse off time can be determined during a test operation.

Master Oscillator OMV

The oscillator OMV transmits the preset values for frequency and pulse off time to the pulse generator. If the customer knows the ideal settings for the pulse generators or if the customer has determined the ideal settings via Test-Oscillator OT 40, then the OMV can already be ordered with the desired fixed settings. An unintended alteration of the parameters through operators is therefore not possible.

Oscillators OM 1, OM 2, OM 3

With these simple oscillators only the frequency can be changed within the setting ranges 1 - 4 kHz, 6 - 20 kHz and
12 - 40 kHz. The pulse off time remains unaffected with 2 μs.

Master Oscillator OM 1:
For synchronization of pulse generators, type SD 30 –SD 351, with a frequency range from 1 – 4 kHz.

Master Oscillator OM 2:
For synchronization of pulse generators, type SD 30 – SD 351, with a frequency range from 6 – 20 kHz.

Master Oscillator OM 3:
For synchronization of pulse generators, type SD 30 –SD 351, with a frequency range from 12 – 40 kHz.
