General Description
Each PT-8000A is equipped with its power supply HN-8000, which delivers 13.8 V DC @ 8 Amps internal
/ 5 Amps. external and additional 50 V DC @ 14 Amp. max., i.e. the overall performance is about 900
W.
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. It complies with special regulations in some countries
regarding power factor compensation (PFC). The HN-8000 provides triple HF shielding and feedthrough
filters.
In addition the HN-8000 provides an auxiliary output 13.8 VDC @ 5 Amp at the back panel, e.g. to
deliver further shack equipment.
