At DC voltages up to approx 30V, pulsed and CW operation are available. Once the DC voltage is greater than about 32V protection is activated which limits the maximum duty cycle to 20% and the maximumpulse width to 100ms. If you apply more than +32V and try to run in CW mode the amplifier module will shut down due to the over duty protection activating. Once the duty cycle/pulse width return to normal limits the protection resets and the module continues to function. So, above 32V DC voltage, pulsed mode only is possible.
