CTU11/12 Current Ratio Transformer

If you don’t need more power output, but you need more current or voltage, a current ratio transformer - the CTU11 or CTU12 – can be used with an ILD1000G to optimise the amplifier output to your application. The CTU11 Current ratio Transformer can often be used where the voltage or current demands of a loop would normally exceed the capabilities of the ILD1000G loop driver. The unit is factory configured to maximise efficiency by matching the loop driver with the loop impedance; this avoids the need to specify two amplifiers as long as the loop driver has sufficient VA. The CTU11 can also be used to reduce loop current where both a small and large area need to be driven with the same loop signal (such as in nave / chancel applications). Always contact Ampetronic when considering the use of the CTU11/12 as there are a wide range of transformation options.
