Vega 750 Instruction Manual
Input Connections:
Input screw teminals – M3 screws with 8.25mm spacing between screw head centres.
Torque Settings for Input M3 Screw Terminals: 0.5 – 0.6Nm
Output Connections:
Ratings:
Single slot, output modules (B, C, L): Two 6.35mm fast-ons per output each rated at 18A or M4 screw
terminals rated at 35A.
Single slot, twin output module (H): One 6.35mm fast-on per output rated at 18A or M3 screw terminals rated
at 15A.
Dual slot, single output modules (D, E): Two 9.5mm fast-ons per output each rated at 32A or M5 screw
terminals rated at 90A.
Maximum Torque Settings for Output Screw Terminals: M3 – 0.5 – 0.6Nm
Adjustment and Derating:
The Vega 750 series is designed to provide a max power of 750W at nominal output voltages. The following
procedure must be used to ensure the PSU is operated within its ratings:
•
Calculate user power for each module (volts x amps)
•
Add all individual module powers together. The total power must not exceed the value given
•
Calculate secondary transformer turns x amps for each module. See the outputs table for transformer
secondary turns
•
Add all modules turns x amps together and this must not exceed amperturns
•
If necessary reduce the loading untill the conditions are met, ie. power and ampere - turns maxima
