Fig.4.2 Maximum output current rating of Type 2719 as a function of frequency
As shown in Fig.4.2, the maximum output current is frequency-dependent. The
maximum power output is 180 VA, which is obtained using exciters with a nominal
load impedance of 0.8 Ω. For other exciter load impedances, the maximum output
rating is as shown in Fig.4.3. This is valid at frequencies, from 5 Hz to 15 kHz. At
other frequencies, the amplifier’s output rating must be derated in accordance with
Fig.4.2.
