VIGIL3 Transformerless Amplifiers

Transformerless Amplifiers for VIGIL3 voice alarm systems are powerful, compact and robust and form part of the VIGIL3 Voice Alarm system.

VIGIL3 Amplifiers form part of our Voice Alarm range of products. They use new transformerless technology and are compact, efficient, and robust.

With 5 modules in the range: Dual 75 Watt, Quad 75 Watt, Dual 150 Watt, Quad 150 Watt, and Dual 300 Watt, each amplifier has a built in power supply and floating transformerless output for increased efficiency. Compared with our VIGIL2 units, they are up to an incredible 66% lighter on a like-for-like basis.

Although amplifier power has increased and the power supply is incorporated, the units themselves are significantly reduced in size. The more compact size results in less rack space – up to 12 x 150 Watt outputs per 12U – which means the rack footprint is reduced. This means that battery size on a Watt by Watt basis is also reduced, all helping with the cost efficiency and space-saving both of which are valuable assets for many companies.


  • Floating, transformerless technology negates the need for heavy and cumbersome transformers
  • Each unit is up to 66% lighter than its equivalent predecessor
  • Far less copper required during manufacture
  • Increased space within the unit for improved airflow
  • Increased power in a smaller sized unit when compared to alternatives
  • Fit up to 1800 Watts of power in one 2U rack space
  • Each unit includes a built-in power supply – freeing up valuable rack space
  • Sleep mode which operates, not only when the system is running on batteries, but also when it is running from mains power
