 OKO DC HV amplifiers with 20 and 40 channels are specially designed to drive the membrane and piezoelectric deformable mirrors. Each amplifier has 40 identical amplifier channels with a gain of 55 (80). Features compact 40x200x280mm size, weight of 1,2 kg, 20W energy consumption and works in any country with AC power supply in the range from 85 to 250 V. Full signal response is linear from DC to ~700 Hz on loads of up to 10 nF. A number of units can be combined (stacked) to drive deformable mirrors with more than 20 (40) channels.
