My Teco VFD specifies a 70 Ohm, 200 Watt braking resistor. I did
some quick looking on eBay and Mouser. It looks like the least
expensive ones are the open tube ones - BUT at around $33 and up. Is
there a less expensive place to buy these or a different way to search
either site that would bring up the less expensive alternatives?

One can get away with a 100 watt tubular or solid resistor if you are
simply operating it HSM and not doing rapid starts and stops ie CNC.

Surplus houses often have similar resistors btw....google is your
friend.

Such as this page....time to find it less than 1 minute...

RS-200 - 200 ohm, 100 watt Resistor, $2.00 each

RS-113 - 200 ohm, 113 watt Resistor, $2.25 each


Use three in parallel for 66.6 ohms at 300 or 339 watts. If one ever
fails, you still have a 100 ohm 200 or 226 watt load.

For those using lower value VFD braking resistors...

RS-35 - 35 ohm 200 watt Resistor,
$4.00 each

Fascinating! Bookmarked!!!

Thanks!!!

The more you present a leftist with factual evidence
