The BCU senses when extra power is needed and boosts the output for up to ten seconds ample time to give air conditioners, power tools and equipment that extra boost of power they need to start quickly and efficiently.The BCU will preserve your tool's life and performance level.
With the new EF30iSE and EF30iSEB generators, Yamaha has introduced the next generation of ULTRA QUIET portable electric generators! This unit has an unbelievable 51dB running sound level as a result of it's silent design, to cut irritating noise. An Economy Control function has been adopted which chooses the minimum engine rpm necessary for the actual electrical load. Here's how it works: Typically, after starting a generator as it's generating power the generator operates at a constant rpm to produce peak power. This is usually the loudest noise level. With "Economy Control," the engine speed automatically changes to match power demand. Therefore, if you're powering only some small appliance or lights, the generator runs at a low engine rpm. Then, as power demand increases, the engine revs up accordingly. What's more, then combined effect of a compact, lightweight, new-design muffler ad optimum distribution of sound-absorbing material combine to produce exceptionally quiet running.
This plug is required to fully utilize your 30 Amp generator outlet with RV's, campers, and motor homes. This is especially important if using a portable generator to start an air conditioner unit, as most will require a minimum of 25 Amps to start.
Our adapter plug takes out all of the guesswork involved in this. It consists of the correct 30Amp twist lock on one end, which fits the standard generator 120V/30A twist lock receptacle, and converts this to a 30 Amp RV Style socket on the other, so you RV can plug in directly!
