Here's an Excelitas LC501 capacitor charging power supply. These are typically used to charge up a large bank of capacitors to a high voltage for a sudden discharge, often in xenon lamp or laser applications.
We purchased this charger directly from Excelitas 5 years ago for a project that never materialized. It's completely unused and has just been sitting on the shelf. Cost was $1700 originally.
No warranty, but if it arrives non-working I will certainly accept a refund at my expense.
