It's 8 channel HV amplifier dedicated to large ion traps like the ones used in the AEgIS experiment. Features:

• +/-200V output range
• 1MHz small-signal BW
• power BW limited by SR (30V/us) and cable capacitance
• quick output disconnect (50us typ) controlled via EEM using OptoMos to limit the noise
• 50R output impedance, able to drive a few meters of cable
• overtemperature protection
• HV capacitors rapid discharge circuit
• compatible with PA94 power stage which provides SR of 700V/us and 300kHz full power BW; External +/- 220V supply is needed (J11 connector) due to higher Iq
