When you're choosing power conversion gear for an industrial project, the first thing to sort out is whether your system runs on DC or AC. The Eaton 11020CL1 DC-DC converter and the 30kVA 208V-480V step-up transformer both sit in that broad inverters and power conversion space, but they answer different questions. This head-to-head will help you match the right one to your input voltage, output voltage, and load.
Quick Verdict
Choose the Eaton 11020CL1 if you need DC-to-DC conversion for an electric vehicle, industrial machine, mobile equipment, or OEM build. Choose the step-up transformer if you have 3-phase 208V AC and need to feed 480V equipment. The Eaton is priced at $287.13; the transformer is priced at $950.00. Neither is better overall because each one is built for a separate conversion job.

Where the Eaton 11020CL1 Wins
The Eaton is the lower-cost component and the only one of the pair designed for DC-to-DC work. It comes from surplus OEM inventory as a genuine Eaton part, with a heavy-duty aluminum heatsink and industrial-grade construction. That makes it a natural fit for vehicles and mobile machines where the electrical system is already DC and the enclosure needs to shed heat. If your project is an OEM build or a fleet repair that calls for a DC conversion stage, the Eaton keeps the component count straightforward.
Where the 30kVA Step-Up Transformer Wins
The transformer handles a job the Eaton cannot: stepping up three-phase AC to 480V at 60Hz. It is new, it is built for AC-to-AC conversion, and it includes ventilation for continuous operation. Its rating is paired with load limits of 24kVA for resistive loads and 18kVA for inductive loads, so it can support real industrial equipment as long as those limits are respected. If your line voltage is 208V but your machines expect 480V, this is the conversion piece that fits.
Product Notes
Eaton 11020CL1 DC-DC Converter
The Eaton 11020CL1 is a DC-DC converter from surplus OEM inventory that is described as in excellent condition. It is a genuine Eaton component with a heavy-duty aluminum heatsink and industrial-grade construction. Its intended territory is electric vehicles, industrial equipment, mobile machinery, and OEM applications, so it fits projects where the power source is already DC. A practical reason to pick it: it provides a defined Eaton part number and a straightforward DC-to-DC stage for a mobile or OEM build. The limitation is that it is not an AC-to-AC transformer, so line-voltage step-up work is outside its role, and the surplus condition means you should match the exact unit to your required input and output before wiring it in.
30kVA Step-Up Transformer 208V to 480V
The Xing Laser step-up transformer is a new AC-to-AC autotransformer that takes three-phase 208V in and delivers 480V out at 60Hz. It is rated at 30kVA, with a 24kVA maximum for resistive loads and an 18kVA maximum for inductive loads, and it has built-in ventilation to support continuous operation. The physical unit measures 20.5 by 17 by 21.5 inches and weighs about 100kg. The selling point here is a defined 208V-to-480V step-up function with a new product condition for line-voltage installations. The catch is that it must stay within the derated load limits, and it is only appropriate for 208V-to-480V 3-phase 60Hz service.
Final Choice by Use Case
Choose the Eaton 11020CL1 for DC-powered electric vehicles, mobile machinery, industrial equipment, and OEM projects. Choose the step-up transformer for 3-phase 208V services that need 480V output, keeping loads within the rated limits. The right pick depends on your power source, not on which unit is more capable.
