Four-channel amplifier 4XD250B

580243

Approval: Part of EN 54-16

Four-channel amplifier with integrated battery charger for emergency power supply of VARIODYN® D1 Comprio. The 4XD250B has 4 independent amplifier channels with 250W in Class D technology. The amplifier may be used both in connection with the VARIODYN® Comprio D1, as well as a DOM. When the amplifier, for example, is used in a DOM without an external emergency power supply, it can be configured on the amplifier.
