Grey VARIODYN® D1 Power Amplifier

The Esser’s VARIODYN® D1 power amplifiers have four independent amplifier channels (100 V) and are compatible with the VARIODYN D1 system. The power amplifier is controlled and monitored by the VARIODYN D1 modules DOM4-8 or DOM4-24 (Digital Output Module). It has general display elements such as 230 V AC mains voltage, CPU status, Collective alarm, 24 V DC emergency power supply. The NF inputs and the control inputs are connected to the VARIODYN D1 module DOM with the input cable.

It has integrated electronic protection against thermal overload and short-circuit on the output. It has efficiency higher than 80 %. Its individual status LEDs indicate channel CLIP, PROTECT, SIGNAL, POWER, LINE and 24 V DC power Back switch contact for sequential remote power.
