Display: The display shows output AC current and voltage on a LCD display.
The Temperature LED indicator lights red if the Power MOS Output Transistors overheat.
The amplifier then shuts-down
The Current LED indicator lights red when output current to the load is exceeding the Cur-
rent Limit value set. The amplifier then shuts-down
The State LED indicator lights green when the amplifier power is switched On
The Voltage or Current Mode LED indicator lights green showing the output mode
The Interlock LED indicator lights red when the interlock circuit is activated
The 0° or 180° LED indicator lights green indicating phase shift from input to output
The Distortion LED indicator lights yellow when output voltage or current clipping occurs
V/C Mode: Select feedback and output impedance modes. The positions are:
Voltage Mode: Provides constant voltage characteristics independent of changes of test
object on the exciter. Gives the best acceleration waveform and is therefore preferable for
most vibration tests.
Current Mode: Provides constant current characteristics, keeping the generated force inde-
pendent of changes of test object.
