I stupidly blew the nice (albeit fragile!) Jaycar SSR we use for weapon control (reverse polarity, d'oh!) but at a 3rd the price what am I missing?

That's your catch :wink:Quote:
Output voltage: AC 24-380V
Output current: 100A
Input voltage: DC 3-32V
Control Method: DC to AC
Whether it has the potential to work like a Jaycar SSR I don't know (depends on the internal make-up). I'm not so clued up on cross compatibility with things like this.
Doesn't the jaycar one say a similar thing? I'll have to dig out my blown one. I figured the load side was just a big switch AC or DC?
From the Jaycar website:

Doesn't appear to be any mention of AC here, but again, I'm not sure if they can be used for both.Quote:
Output Circuit
€ Load Voltage: 0-30VDC
€ Load Current: 0.02-100A
€ Max On-State Resistance: 0.007Ohms
€ Max On-State Voltage Drop: 0.35V
€ Max Turn On Time: 0.5ms
€ Max Turn Off Time: 0.5ms
€ Max Surge Current: 240A (10ms)
Input Circuit
€ Control Voltage: 3-32VDC
€ Control Current: 28mA max.
€ Min Turn Off Voltage: 1.0VDC
€ Input Resistance: 1.2kOhm
It appears Jaycar do 2, one with a VAC output and one with a VDC.
Searching SSR on eBay and omitting VAC brought up some results, although finding a DC one (that actually is!) with a decent amp rating (80s +) is porving impossible let alone a good price.
This is the best I could do:

60a
And 80a at a premium:

PJ, I have another of the ones I sold you a while back, would you be interested in that? I don't have anymore spare so don't immediately blow it up this time :lol:
Hey Tony, that would be great! I'll try and make this one last longer!
I need to regulate the 24v in Bitza down to 12 for some cooling fans what's the best way to do this?
Most BECs regulate to 6-8v, or boosters increase voltage. Anyone know of a solution?
I doubt the current draw would be much so resistors could be a possibility?
Found this:

Would this do?
Bit pricey but thanks for the link.
Given the low current draw of the fan I'm hoping a resistor will do but without knowing the exact amperage I can't calculate which resistor. Time to experiment!
