Power amplifier 2XD400

580232

Approval: G 210122
Part of EN 54-16 certification 0786-CPD-20997


Usage
The power amplifier have two independent amplifier channels and are compatible with the VARIODYN D1 system. The power amplifiers are controlled and monitored by VARIODYN D1 DOM4-8 / DOM4-24 control units.

LF/Control Input
The two low frequency inputs and the control input are connected by cable (Part No. 583491) to the VARIODYN D1 DOM.

100 V Outputs
Symmetrical ungrounded 100 V outputs are available on the "OUTPUT 100 V" terminal strip. The 100 V outputs of the two double amplifiers are connected via cable (Part No. 583477.21) to the VARIODYN D1 DOM. Once a cooling element reaches a critical temperature, the load for this channel is disconnected by relays and is once again connected by relays upon reaching a secure temperature.

Power Connection, Battery Connection
An IEC connector for power connection as well as a power fuse can be found on the back of the amplifier. The power cable is supplied. The power amplifier may only be operated via a three-wire AC power cable with a non-fused ground connector.
The 24 V emergency power supply is connected to a designated 2-pin terminal.
