Sega pushes the Mega Drive Mini global release to 2019 | Lrd12 Overload Relay

I’d like to know how this does around town and also on the highway (independently) when the battery is exhausted. Maybe we should get standard EPA measurements with the battery starting empty in addition to the eMPG test.

If you do not know the exact value of each cost, you could enter an estimated percentage based on the cost of goods.

Overall though, you’re just talking about increased RMS voltage allowing more current; the more current the more burn, heart arrhythmia and neuromuscular effects.

Note: Not all certifying agents offer online lookup, and some have a lag time for posting new certificates. If you are unable to find a certificate online, contact the certification agency or supplier for further verification.

• Pick your features: Models come with either a recoil handle (similar to a lawn mower) or electric push-button start, and one or more outlets to plug in extension cords. Some include covered outlets, illuminated control panels or automatic shutdown in case oil runs low. Portables can weigh from 100 to 250 pounds, so you’ll want to buy a wheel kit. With the wheels installed, a generator can be rolled like a wheelbarrow into place.

Found said bare wires and had the ultimate Homer Simpson moment after separating them (probably when the lights weren’t plugged in), and thought ‘hey wouldn’t it be fun to complete this mains circuit across my body’. I didn’t really check with the lights lit up, but I was having a whale of a time juddering and screaming for a few seconds till somehow I managed to let go of the wires

Oh well… That industrial relay has ‘almost’ the same contact ratings of a simple songle srd-05v sl-c relay (specifically the C form/single phase). But I’m sure it won’t last as long as 20y+ in such harsh environment.

It’s good to see a snubber on the design (that’s often omitted on DIY designs I’ve seen). There are a few TRIACs that are designed to commute highly-inductive loads (“snubberless” is the marketing term I’ve seen) — may worth looking into them to reduce the BOM.

TRIACs have very low junction voltage / resistance especially when compared to the load they are driving. When they are overloaded they heat causing the the junction voltage to increase rapidly causing exponentially more power to be dissipated by the TRIAC instead of the load. This whole process seems to take about a nanosecond and ends with a small amount of the plastic casing still attached to the legs.

the scariest thing I have ever seen/been around was in a fuel terminal at an oil refinery. I couldn’t figure out why we had printers, plotters, Apple II’s and monitors dropping like flies.

TJ may also want to mention on his project page that without a choke, the TRIAC will dump out a ton of EMI (that’s why most commercial dimmers have to have a choke in series with the load to be able to get FCC certification).
