TDK-Lambda ESS-200-75 Power Supply (Pallet of 8)

TDK-Lambda ESS-200-75 Power Supply (Pallet of 8)

This is a pallet of 8 power supplies being sold as a lot.  None of them have been tested.

6 of the 8 are in good cosmetic shape and believed to be working, but have not been tested.

Of the remaining 2 one is missing the top cover, the other front face is broken ( see listing pictures)

The ESS‑200‑75 is part of TDK‑Lambda’s legacy ESS series—a rack-mountable, programmable DC power supply designed for high-power applications (e.g., RF amplifiers, DC motors, magnetic coils)
