KT-250 transmitter is designed on the basis of five joined KT-50 transmitters mounted in an aluminum rack connected via the synchronization module. It is designed to make powerful rectangle-shaped current pulses.
The KT-250 complex consists of five KT-50 transmitters and the removable control unit ensuring synchronous functioning with the EM receivers and the ballast resistors for uniform loading with adjustable ballast with the 10-steps change of resistance (12-120 Ohms).
