VARIODYN® D1 Four Channel Power Amplifier

VARIODYN® D1 Four-channel Power Amplifiers are available with built in battery charger for emergency power supply. They have 4 independent amplifier channels each with 125 W in class D direct drive technology.

VARIODYN® D1 Four-channel Power Amplifiers are used with a separate PSU, in this case the internal battery charger must be disabled.
