Transistor frequency converters -40/20



TMS320F241F-based management system provides all necessary protections and interlocks (configuration bytes include 32 bits, each of which initiates a corresponding protection or interlock and helps modify its installation).


Power range 1:1000, accuracy of power control 0.1% due to the closed loop feedback control system combined with feed-forward control for voltage fluctuations specified in the GOST.


The generator is equipped with a certified input power high-frequency filter and varistor protection.


The digital control panel on the front door of the generator cabinet displays actual values of control signal, frequency, power, current, voltage and other relevant parameters of the generator.


High output power factor of the generator allows to connect the generator with an inductor using a very simple and cheap shielded cable assembly instead of an expensive coaxial high-frequency power cable; tank capacitors operate under normal conditions.


Energy saving, reduction of operating costs due to the absence of water cooling option commonly used in similar generators.
