How a Power Outage Can Damage Your Power Supplies

Get Your Damaged Lambda Power Supply RepairedWhat?  Hold on….a split-second power outage can damage your power supplies?   Why?  How?

There are a few variations on why and how a power outage can wreck your power supplies.  It depends on the kind of interruption.

If it is just a momentary loss of power, the load of the power supply can cause a spike in current that damages the output of the power supply by the partial shutdown and the restart.

More often, there is a spike on the main power to a plant when there is an interruption and restoration of power.  This spike will damage the input side of the power supply.

In this particular Lambda example (pictured) there was indeed a power outage in the plant reported.  After the power outage, the main power board on this Lambda D60066 was damaged on this power supply (input side), a known weak spot, so it was quite possibly caused by the Input spike.  Lambda power supply repairs were definitely needed.

The good news is that most power supplies survive this damage and can be repaired.  If you need power supply repairs check first to see if your equipment is still under warranty.  If so, contact the OEM about repairs. If it is out of warranty, hopefully you have found a go-to repair center.

If not, contact an independent industrial electronic repair center to find out if they are a good fit for your company and your particular repair needs. They should offer free evaluations for your damaged power supply and other equipment, and a free quote for repairs (no bench fees!).  They should also provide repair reports if requested and a good warranty of at least one year that covers both parts and labor.
