I had a similar issue several years ago, and turned out to be the CB on the |
back of the system. |
Swapped it out, and all is fine since. |

Hi Mitchell, |
Could you put some images of the power supply along with the model number. We had a similar UV lamp power supply failure. I had to change the high power MOSFETS and diodes in the unit along with some PTC inrush current limiter. These lamp drivers are fairly advanced as they constantly monitor the power lamp power and lamp current. I had used the following components to get the supply up and running. Repairing this unit involves disassembling the complete power supply and do board level repairs. These parts were ordered from Mouser Electronics. |

Lamp power supply will not turn on after lamp failure. |
We had a lamp (350 W) pop on our system. |
Cleaned up and installed a new lamp. |
When we start the power supply the breaker in the back of the system trips. |
Specifically, it trips when we press CP. System starts at STAND-BY. |
Press "ON" and the display shows "READY". Press CP and it displays "Wait..." for a second and then trips. |
We checked for shorts and all looked good. We swapped to the other 220 Volt plug in the back and it trips as well. |
Any ideas on this? We are not sure if the start box or the supply itself is the issue. |
