Linear Power Amplifiers

YMC LA series Power Amplifier are designed to drive MS series Modal Shakers and MS series small vibrators. Features:  Adjustable RMS output–current limit  Low or high output impedance  Low distortion over wide frequency range  Extensive built–in protection  Operating mode (current or voltage), current state and interlock input disabled  Rear panel voltage and current monitor points  Multifunction display (True Colour LCD) showing approximate output current and output voltage, clipped output signal, temperature overload, current overload.  LA60 and LA–100 power amplifier is built–in Sine signal generator from 5Hz to 30kHz with 60/100VA power output.
