The VX-050DA is a 500W digital amplifier module used in the VX-3000 system. It complies with the European EN54 standard for fire alarm systems. The module is a 1-channel class-D digital amplifier module that saves power and is lightweight.
The VX-050DA can be set to operate in standby mode to reduce power consumption. The module requires the use of a dedicated controller VX-3004F, VX-3008F, VX-3016F and an emergency power supply VX-3000DS or VX-3150DS.
