Is Heidelberg 00.785.0031/01 KLM 4 and Heidelberg 00.781.4754 KLM 4 PLUS the same

Hi,

Is Heidelberg 00.785.0031/01 KLM 4 and Heidelberg 00.781.4754 KLM 4 PLUS the same. What is the difference. My machine is an 1995 SM 74, the current KLM4 installed has Heidelberg part number 00.785.0031/01. I need a replacement since its not working anymore and I am being offered 00.781.4754 KLM 4 PLUS as replacement. Hear from anyone soonest. You can also email me at pressmachines@yahoo.com
Thanks.

 

Hello !
I have the same question ?
1.Were you able to replace KLM inverter ? Did KLM plus worked ?
2.Did you purchase original from Heidelberg ? I saw a lot of modules on eBay. What do you think about that ?
3. Does anyone knows what signals there is on X5?
Thanks

 

Both modules are compatible. KLM4 Plus has a new IGBT which is more reliable than the old generation.

Whatever you can find on ebay are after market products mostly from China. Some works perfectly and some are real garbage.

 

Thank You very much. For the moment iu was able to repair it.
