Hello. I am having a problem with my laser which I hope someone can help or advise on.
We just replaced our 150 RECI watt tube because we thought it was discharged. That was not the case it was
simply not outputtng at high power levels. As such,
The new tube will not fire at anything above 40%. Even then, as the power level goes UP the power of
The beam appears to go down. I checked a lot of things and all things point to the power supply.
The RECI 12 power supply is not showing any fault codes on the panel. When the laser is not firing it shows
An output of 0 volts as expected. At 10% laser power the RECI 12 shows an output of over 23 Kv. As I increase
The power level, the voltage output drops at a fairly linear rate, such that by the time I’m telling it to output
Over 60% power, the voltage output is around 9 Kv. This seems counter to what I would expect as I assume
More voltage is necessary for more laser power.
The power supply is pretty simple – needing only the TTL and PCM and ground. Assuming the PCM is good, and
I have no reason to assume it is not, the problem must be the power supply. Do you agree with this
Assessment? Otherwise, what else can I check? Can you guess why the power is dropping as the power level
Request goes up?
Any help you can provide would be appreciated. We are open to replacing the power supply if needed.
Warmest Regards,
