The KEP LFG-2500 Low Frequency Generator has a audio-frequency modulation mode, protection against overcurrent, smooth and scalar adjustments of the output voltage.
The KEP LFG-2500 features a special way of low-frequency modulation of the output signal. The modulation is performed by pulses of the rectangular shape with 1.5-3 Hz frequency, so that during the first half period of the modulating voltage the signal with 1024 Hz frequency is generated, while during the second half-period – one with 2048 Hz frequency.
The advantage of this modulation method is that if the receiver accepts frequencies of 1024 Hz and 2048 Hz (for example, the KEP P-900), it would be possible to switch between the two on the receiver itself. In the continuous generation mode, the signal with 1024 Hz frequency is generated.
