Issue
My Selador fixture doesn't power on or has a single cell that doesn't power on. How do I replace the power supply and what parts do I need?
Explanation
Multi-cell Selador Classic fixtures have a power supply in each segment. If the entire fixture isn't powering, you'll need to replace all of the power supplies, but if it's just one cell, it is NOT required to replace every supply.
As far as the parts necessary for the replacement, ETC has historically used 2 different power supplies Selador Classic. Beginning Apr 2021, we switched from PS342 to PS 496. 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 reversed pinout on the input, and a different number pins on the output header.
If your fixture was built after April 2021 and already has the smaller PS496 (pictured below), all you need to replace it is a new PS496.
If your fixture was built before April 2021 and 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 DC harness.
The kit does not include a new AC harness, as different fixture sizes require different size harnesses. The existing harnesses can be reconfigured to work with the new power supply and instructions are outlined in the video below, but, if you are not comfortable disassembling and reassembling the harness, we recommend purchasing the appropriate size harness for your fixture.
| Fixture Length | 11" | 21" | 42" | 63" |
| AC Harness Part Number | 7400B7042 | 7400B7043 | 7400B7044 | 7400B7045 |
For European customers, please contact your local ETC office, as the above kit is only suitable for ETL (North American) fixtures, not CE
If you're unsure which power supply you have, contact ETC Tech Support with the serial number of your fixture and they can help you determine what parts you need.
