Feature
Long life cycles: 1200000 times charge and discharge.This unit seems extremely well built, especially compared to the original inverter. The heat-sink is very solid and the whole case is water tight, great to have on a boat! Output voltage is consistent, regardless of the fluctuating source voltage from the alternators when the boat is running.
Great for building a prototype of an electronic circuit, With referencing numbers printed on one side for easy reference of individual holes.
The scale of the circuit can produce different sounds, while different keys correspond to different scales. The play of the electronic organ is to use the fingers to press different keys to produce different scales.
Note:Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid.Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
