PS-2001

  • 0mVp-p spikes of power source (yellow chart)
  • 0mVp-p spikes of diodes photo emission (blue chart)
  • 20nsec period (50MHz band)

BK Precision 9183B

  • 150mVp-p spikes of power source (yellow chart)
  • 20mVp-p spikes of diodes photo emission (blue chart)
  • 20nsec period (50MHz band)

The PS-2001 solution is a specially designed rechargeable batteries combine with Low Dropout Stabilizer Circuit

The nominal voltage of the PS-2001 Power Supply is 2V with current 20Ah and regulation to load from 0 to 20A. The USB interface is used for executable application for current control. This application can be customized according to used needs. 


To increase the stabilization coefficient and reduce the current consumed in quiescent mode the composite transistors are used. To reduce the voltage drop across the regulating element the powerful field effect transistors are used, the source drain resistance of which in the open state is hundredths of an Ohm . The source circuit has an automatic mixing circuit to apply the characteristic of the drain current from the gate source for high current regulation.
