Linear and Bipolar High Voltage Power Supplies
Serie NLB from 6.5V to 350V / 35W to 1.4kW

Bipolar linear regulated power supplies supply one output voltage, where the value and polarity is adjustable. The mains voltage is transformed to the appropriate level and rectified.

The rectified voltage charges a bank of capacitors of the intermediate circuit to a constant voltage, which it is fed, via a set of serial power transistors, to the output.
The output stages of the positive and the negative circuits are switched together in a push-pull manner. The regulation transistors define the final stability of the output voltage and the regulation speed. Bipolar power supplies are able to operate as 4-quadrant power amplifier. (optionally also for active loads).

Features:

  • single output power supply with adjustable bipolar output voltage and current; instantaneous change of polarity
  • voltage and current setting with 10-turn potentiometers with precision scale; the adjusting knob can be locked
  • when equipped with an interface or with the analog programming, fast programmable including change of polarity
  • short circuit proof and allow unlimited operation with full current in short circuit condition
  • 4½ digit DVM for voltage and current (for table-top models)

Series NLN from 6.5V to 500V / 35W to 1.4kW

The mains voltage is transformed to the appropriate level and rectified. The rectified voltage charges a bank of capacitors of the intermediate circuit to a constant voltage, which it is given via a set of power transistors to the output.
The series transistor defines the final stability of the output voltage and the regulation speed. Optionally a set of power transistors parallel to the output can act as a current sink to provide active pull down ability. The design of linear regulated power supplies is optimized for fast programming speed.

Features:

  • voltage and current setting with 10-turn potentiometers with precision scale; the adjusting knob can be locked
  • output voltage and output current are fast programmable
  • no output capacitor
  • all units are short circuit proof and allow unlimited operation with full current in short circuit condition
  • voltage and current regulation with automatic and sharp transition; control mode indicated by LEDs
  • 4½ digit DVM for voltage and current (for table-top models)

Series HCB from 1.25kV to 20kV / 1.4W to 200W

Bipolar HV power supplies consist of 2 switch-mode controlled HV sources which are connected to the output. In principle, the rectified line voltage in each source drives a square wave generator of fixed frequency, whose AC voltage is transformed, rectified and filtered, producing the positive or negative output voltage. For regulation, the square wave voltage is pulse width modulated. The operation is contra-moving, and the output can be adjusted with continuous zero crossing.

Features:

  • light-weight
  • in units with 6,5kV and higher the HV-components are moulded in (removable) silicon resin
  • short-circuit and flash over proof
  • unlimited operation with rated current in a short-circuit condition
  • voltage and current regulation with automatic and sharp transition; control mode indicated by LEDs
  • 4½ digit DVM for voltage and current (for table-top models)
  • 4-quadrant operation possible also for active loads and unlimited power sinking
