I bought two of these remote-controlled power strips. The first was broken after about 2 months, the second followed about 14 days later. The reason lay in the very simple electronics that provides remote control of the power strip. The electronics operate by switching relays which require a control voltage of 24 V DC. This direct current is transformerless a diode bridge rectifier and a combination of resistor and capacitor directly from the mains voltage (!) Of 240V AC generated. Since the diodes used have high dielectric strength, these partially "blown" after several shifts, which made impossible the continued use of power strips. Here Brennenstuhl must rework necessarily !!! A return to the dealer and a repair or replacement by the manufacturer should here have not fixed, because the product is technically immature and as such I would again receive an inferior product. As a solution, I've a small transformer built into the power strip instead of the resistor / capacitor combination to generate the necessary AC voltage for the rectifier. Since the power strips work without problems. The guarantee is therefore but also away. So be careful!
