AUDAC TRU425 voltage transformer

Line Transformer Unit 4x 250W The TRU425 is a line transformer unit consisting of four toroidal line transformers allowing low-impedance power amplifiers to be used for powering large public address audio systems with constant voltage levels of 100 Volt, 70 Volt and 50 Volt. Each line transformer has a rated power of 250 Watt, with an input impedance selectable between 4 Ohm and 8 Ohm. The secondary side of the line transformer has power taps for use in 100 Volt, 70 Volt and 50 Volt constant voltage audio distribution systems. Unlike regular line transformer units, the TRU series has a special internal decoupling network which make them suitable for use with Class-D power amplifiers. The line transformers are housed in a solid constructed 19” rack mounting housing with a height of one single rackspace. The connections for both in and output are performed using reliable Terminal blocks.
