AC Current Capacity:
Input - 20 Amp capacity required
Output - 12 - 20 Amp RMS * (maximum, all outlets combined - continuous)
* Due to the Power Factor Technology circuit, available RMS power varies with the reactance of the load (vector). However,
this only affects the circuit breaker for continuous RMS current draw. Since power amplifiers will require high transient current
demands, the IT-Reference 20i will never succumb to current compression. Quite the opposite, in fact, it will buffer the power
amplifier’s power supply, while lowering the AC input impedance, allowing power amplifiers to work more efficiently.
Linear Noise Attenuation:
