1.5kVA transformer that steps up from 100V to 117V. - Model: UL-1500UP - Input Voltage: 100V - Output Voltage: 117V - Maximum Output: 1.5kVA - Manufacturer: KASUGA MUSEN CO., LTD. Thank you for viewing. This is a listing for a 1500W AC100V to 117V step-up transformer. The secondary voltage on the tester shows 122.9V, but this is because the primary voltage is 104.9V. It is stepping up 18V. If anyone needs this, please consider it. Additional note: There is rust on the casing. If you wish, I can easily remove the rust and lightly paint it with lacquer before sending it.
