Vega Series Customizable Power Racks
15 kW – 480 kW
Customizable high-power racks built from 15 kW 3U regenerative loads and DC supplies — mixed and matched to the test requirement rather than bought as a fixed configuration.

Detail views
The same five-bay row on the floor in Tustin, before shipping. Castors, not a plinth — these are built to be rolled into a customer’s test area and levelled there.
From the side, the depth of each bay and the run between them — the part of a rack build that decides whether it can be serviced later.

Capabilities
- Built from 15kW 3U regenerative loads or DC power supplies, mixed and matched to the test requirement
- Up to 480kW loaded or supplied at efficiencies of well over 90%
- 21U, 30U, 35U, and 42U chassis sizes; up to 180kW in a single rack, 480 kW total in three bays
- Auto-Ranging output stage delivers full power down to 1/3 of the voltage range
- The regenerative load and bi-directional source stages recover energy back to the AC grid — nearly 95% of the loaded energy
- Integrated function generator based on 4096 data points; arbitrary mode with up to 100 freely configurable steps
- Analog and USB interfaces standard; optional GPIB/IEEE three-way interface, plus LabView VIs for USB, RS232, GPIB, and Ethernet
- PSI 9000 programmable internal resistance (Ri setting) simulates wiring and connector impedance without buying hardware
What it is bought for
Each of these sets out the bus, the clause and where programs get caught out.
