10kW 6 BT139 TRIAC dimmer circuit by connecting the power line were raised cardiac dimmer circuit (BR100) triggered 1Mohm can be adjusted by a potentiometer. Triac for cooling medium size fin coolers and 12v dc fan was used in practice cooler box contact to the absence of a triac in the installation of isolator was used half deficit to be used or cooling any part in contact with where they do isolators should be used
Triac Dimmer circuit diagram;
CAUTION triac BT139 screwed into the cooler parts of the central leg that A2 is associated with high voltage has to be careful in this section. Be careful also is working with high voltage capacitor circuit connections Beware + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles

USB Battery Pack DC to DC 5V LM2678 Converter LM3914 Voltmeter
Dc to dc 5 volt converter.. converter circuit LM2678 (5A step-down regulator) based on the layout of the board quite well designed also LM3914 prepared with LED voltmeter Node voltage monitoring is easy In addition to “backup” backup battery has sections 8 AA batteries can be connected. Between 7 …. 40v DC adapter to the DC input jack can be connected subcontracted with 5v devices or devices that can operate via USB portable power supply for the supply of …
Finally Voltmeter prepared with LM3914 circuit is intended as an additional module for printed circuit board pcb circuit separately so that you can use for different projects used instead of the normal LEDs SMD LEDs can also be connected.
