Due to parts obsolescence from the power supply manufacturer, ETC changed the PSU in Selador Classic beginning Apr 2021

Description/Explanation of Issue

The new PSU is a different size and requires an adapter plate to be able to attach the new supply with the existing standoffs in the fixture. It also requires new harnesses due to a different pinout on the input, and a different number pins on the output header.


If your fixture already has the smaller PS496 (pictured below), all you need to replace it is a new PS496.

If your fixture has the larger legacy PS342 (pictured below), you will need to order part number 7400K1007. This kit includes the new power supply, the standoff plate, and the new harnesses. 


For European customers, please contact your local ETC office, as the above kit is only suitable for ETL (North American) fixtures, not CE

When replacing a PSU with the new PS496, the black and white wires on the AC power harness need to be swapped


If replacing a PSU in a multi-cell fixture, it is NOT required to replace every supply.
