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).

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.

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.
