Title: ERS 548 diode blocks Post by: The Slab Bacon on December 21, 2005, 09:00:51 PM Hi guys, this one has got me. I recently picked up a handfull of moulded diode blocks, but i cannot cross reference them to find their ratings. They are the usual black moulded blocks with flat spade connectors. theese things sream high voltage. I have even done a google search and come up blank. All that is on them is a diode symbol and "ERS 548" with
"H7K" on the next line below that. Anyone out there got a clue??? Any help is appreciated, Thanks in advance! de KB3AHE Title: Re: ERS 548 diode blocks Post by: Warren on December 21, 2005, 10:46:05 PM Frank,
I did some more web searching and came up with "Microwave Oven Diode" on: http://www.bio.tamu.edu/instshop/COMCAT.TXT (hint do a find for ERS-548 on the above web page) I know that's not much to go on but perhaps you can find out what voltages/currents microwave ovens typically use and get a ballpark idea.

My guess is that the H7K indicates a P.I.V. of 7000 volts. Warren K2ORS/WD2XGJ Title: Re: ERS 548 diode blocks Post by: W1RKW on December 22, 2005, 04:33:10 AM The ERS548 is an ECG548's evil twin
Title: Re: ERS 548 diode blocks Post by: The Slab Bacon on December 22, 2005, 01:14:10 PM thanks guys! I did a search for "ecg548" and came up with a microwave oven diode AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
rated 12Kv @ 750mils. That definately looks like it. I wuz hoping for a for as little higher current rating, but it will probably work as those things are usually a little conservatively rated. thanks gain, And have a very Merry Christmas!!!!!! the Slab Bacon |
