650A
The 650A is a global power-factor-corrected AC/DC converter providing multiple DC outputs and AC ring outputs. The unit is autoranging and accepts 85-264 VAC, 47-63 Hz AC input, and provides 330 Watts total output. The unit provides multiple DC outputs as follows:
- +5.1 VDC, 28 A
- -5.1 VDC, 1.0 A
- -48 VDC, 4.5 A
- +8 to +14 VDC, 1.6 A (fan speed control)
- -150/-115 VDC, 200 mA (neon bus)
The power unit has 3 switch-selectable ring outputs:
- 85 VAC RMS, 80 mA, 20 Hz, centered about -48 VDC, 180 mA
- 72 VAC RMS, 8 to 80 mA, 25 Hz, centered about -48 VDC, 180 mA
- Two 28 VAC RMS (56 V eff), 220 mA, 50 Hz biased about -48 VDC and 0 VDC, 70 mA balanced
The fan speed is controlled by the +8 to +14 VDC (+12 VDC nominal). The output voltage is a function of the ambient inlet air temperature at the bottom of the power supply. The fan output voltage is +14 VDC if the FANALM signal is active.
