Hello!

I just recently bought a PRO1500E UPS to protect a pre-press equipment. I bought this model because the company that sold me the machine told me that I needed a UPS with at least 1500 VA. I own a printshop and I have a Ultre 4000 Imagesettler which is a machine that prints negatives.

Anyway the problem is this, I plugged my Imagesettler to the UPS and as soon as I turned it on, "POP" the power supply of the machine burned out. The new part cost me $1000 and I am ready to install it again, but I have my doubts if I plug it to the UPS again, I don't want to spend another $1000.

So my main questions are: why did this UPS burned the power supply? and should I take the risk and plug my machine to this UPS again?

Thank you!

Thank you for the post.

After reading your post I started doing some research about your application.

The reason why the power supply "popped" is because the spec on your machine has an acceptable voltage range of 96 Volts to 130 volts.

The device you have Pro1500 E starts up in the battery mode. The wave form is a square wave and has a peak to peak voltage of 150 RMS voltage. This Pro E Series is used in most computer and telephone applications but the power supply you have is real sensitive.

The device that you are using requires a True Sign wave UPS. I would even suggest that you use an On-line UPS (Endeavor Series). The voltage for the Ultre 4000 Imagesettler should never see a disruption.


This is the definition of a ON-line UPS.

A true on-line UPS constantly runs connected equipment on recreated AC power. In short, the UPS converts incoming AC utility power into DC power and then back into clean AC power to operate your equipment. This “double-conversion” process ensures consistent power quality that’s completely isolated from any utility power disturbances. If the utility AC fails, the UPS continues to run using it's internal battery system

Thank you so much Jeff, I totally understand now what happened! I would check those Endeavor Series UPS.

And since you already did a research on my Imagesettler which Endeavor UPS model do you recommend?

aemena,

It looks like the Endeavor 1000RM2U....

Ok, thank you Jeff
