This equipment measures the voice coil temperature of at most 5 loudspeakers.Signal source corresponds to all kinds of signals in the reach of the 20kHz from 20Hz(sine wave, white noise, pink noise, standard load test noise and music source).
A measurement item indicates a chart and the value to time between the temperature and the input voltage.
Measurement temperature range; 40℃～400℃
Environmental temperature; -40℃～100℃
Speaker DC resistance range; 1.5Ω～40Ω(at 20℃)
Material of voice coil; copper or aluminum
Maximum input voltage; 70Vpeak(While a noise source is applied, the power amplifier must not be clipped by a peak of the noise signal.)
Maximum input power; 400Wpeak
Response selector; 2 positions to change low-pass cut off frequency
Power requirements; AC100,110,120,200,210,220,230,240V±10%(Voltage can be specified at the shipment.)50/60Hz
Power consumption; Approx. 50VA
