This so-called dc-dc converter is shit full! When feeding it 12 volts and 7-8 amps could not maintain the voltage at the output of 40 volts, it fell all the time to 27-24 volts, while the coil produced a wild high-frequency whistle, and the more the topic load in the higher frequencies went whistle. When connecting a 150 w load, the converter simply turns off and does not work. When connecting one 50 w, 12 v halogen light bulb-the same result, the converter turns off. About any 600 w load and speech can not be! Money to the wind! Do not buy this product!Z. s. The only thing that turned out in the converter is good is the aluminum radiator-large and high-quality.

Order from june 17 came to moscow on september 1, from which i conclude that the delivery of aliexpress supereconomy shipping is a flock of chinese, queuing carrying parcels on foot.
