So the load of this psu in the machine as per equipment engr told me is "focus assembly" for the moment i dont know this thing. The machine they called implanter (semiconductor wafer fab machine). The power supply rated capacity is 130Vdc 5mA.
If it's 130vdc at 5mA, you need a 26K ohm load that is for a watt. your load will be dumping 650mW. If you are series connecting the resistors with equal values the wattage will be divided by the number of resistors. Just hit your electronics supply web page and look for the combination that will give you 26K and one watt. Pick up some proto boards to solder them or get some clip leads.Hello All...yesterday i been inside the fab to check the load structure....So the load of this psu in the machine as per equipment engr told me is "focus assembly" for the moment i dont know this thing.

Sorry...tpyo...130KV130V or 130 kV?
and 5 mA?
Thanks...can you show me the photos and wiring diagram? thanksIf it's 130vdc at 5mA, you need a 26K ohm load that is for a watt. your load will be dumping 650mW.

If you are loading a 130KV supply get back to me and I can get you some photos of some working loads that are in the ball park of what you would need. No oil or glass tubes, just a bunch of resistors and an acrylic plastic frame.
I work for a company that made wafer implanting machines back in the eighties and have worked on some of the hardware along with testing and repairing the high voltage supplies.
Hi...do you think there's a "ready to use" electronic load or resistive load or any load method that i can purchase? let say cost is not a problem....thanksi suggest you look at Caddock high voltage resistors
such as the MX500 series
MX585 is rated at 32kV (maximum continuous voltage) and a maximum resistance of 1000 Mohm and 10W
i suggest you arrange a series and parallel configuration to meet the resistance, voltage and power requirements
i expect they have a few application engineers who can help with details
