flexiBrute DRSSTC Modulator

 flexiBrute DRSSTC Modulator / Interrupter

fThe flexiBrute DRSSTC Modulator is our professional grade modulator designed for use with both Solid State Tesla Coils (SSTCs) and Double Resonant Solid State Tesla Coils (DRSSTCs). This modulator (or interrupter as it is sometimes referred as) is used to control the output of a pulsed Tesla Coil by sending it pulses of varying pulsewidth and frequency. This controller is a no-nonsense solution to that providing the user with maximum flexibility but at the same time simplicity as only two knobs are required for operation. One knob controls frequency while the other controls pulsewidth. It doesn't get simpler than that folks!

However, don't let the simple appearance fool you. The inside is anything but simple. This unit features several protection features as well as maximum flexibility. The end user can internally program the range of pulsewidths and frequencies which are required for his / her specific Tesla Coil system. An infinite number of pulsewidth and frequency ranges is possible. There is also a low-frequency / high pulsewidth bypass mode which allows one to pulse the coil at very low frequencies and long pulsewidths. Maximum pulsewidth and duty cycle protection is also provided as well as five (5) status LEDs.

The modulator features both an electrical BNC output which is compatible with most 5V logic systems as well as a fiber optic output with an ST type connector.

This modulator can be used with any DRSSTC system, including our microBrute and miniBrute kits, and is suitable for low-power DRSSTCs as well as monster DRSSTC systems utilizing paralleld CM600 full-bridges.
