General
Each model PT-8000 A/B is equipped with its appropriate power supply all named HN-8000. The only
difference in appearance for the PT-8000A-model and the PT-8000B-model is the final amplifier DC
input power instrument at the front panel.
The HN-8000 is a switching power supply with industry standard. It complies with special regulations in
some countries regarding power factor compensation (PFC).
Operating voltages from the mains can be in the range of 90 VAC to 260 VAC without any degradation in
output power. Only the efficiency will vary slightly. The HN-8000 operating temperature is controlled by
up to 4 fans (PT-8000B). The HN-8000 accompanied with the PT-8000A and PT-8000B delivers 50 VDC
@ 15Amps and 100 VDC @15 A for the high power B-model.
