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 900 series is designed to provide a max output power of 900W at nominal output voltages (subject to input
voltage restrictions). 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 the 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 the module turns x amps together and this must not exceed the ampere turns
•
If necessary reduce the loading until the conditions are met, ie. power and ampere-turns maxima.
