ESSER Systems

Application

The power amplifiers possess two independent amplifier channels and 100 V toroidal core output transformers and are compatible with the VARIODYN® D1 System. The power amplifiers are controlled and monitored by the VARIODYN® D1 modules DOM4-8 and DOM4-24 (digital output module).

Connections

• One combined AF/control input

• One dual-channel 100 V output

• One mains supply

Indicators (per channel)

• One green POWER LED

• One yellow error LED

• One green SIGNAL LED

• One red CLIP LED

AF/Control Input The two AF inputs and the control input are connected to the VARIODYN® D1 DOM module via a cable (part number 583471.03).

100 V Outputs The symmetrical ungrounded 100 V outputs are available at the connector labeled “OUTPUT 100V”. Both 100 V outputs are connected to the VARIODYN® D1 Module DOM by cable (part no. 583476.02). In the event that the heat sink reaches a critical temperature, the relay load for this channel will be disconnected and then reconnected upon reaching a safe temperature.

Mains Supply

A (European) low power socket for mains supply connection, as well as a mains fuse are located on the back surface of the amplifier. A mains cable is supplied. The power amplifier can only be operated via a three-wire system feed with a protective ground wire.
