The E81.A1K-I1 series piezo amplifier is designed for driving capacitive loads high-current, high-power applications. Its output voltage is up to 200V, the average output current is up to 5.4A, and the output bandwidth is up to 5kHz.

E81.A1K-I1 is equipped with a powerful heat dissipation module to meet its powerful output capacity!




Features




· High power output
· Output voltage up to 200V
· Analog signal control
· Bandwidth up to 5kHz

 

Operating Bandwidth




The operating bandwidth of the E81.A1K-I1 series of high-power piezo amplifiers can reach 5kHz, that is, its bandwidth output capability. The frequency and voltage curves of different capacitive loads are shown in the following figure.
 


In actual application, the achievable drive bandwidth capability under different capacitive loads can be estimated according to the average current calculation formula I=UfC, where U is the output voltage, f is the operating frequency, and C is the capacitance of the capacitive load. For example, when driving a 25μF capacitive load, the driving frequency can reach 1kHz under a driving voltage of 200V; while driving a 100μF capacitive load, if you want to drive the frequency at 1kHz, then E81.A1K-I1 output drive voltage is around 60V.
