C/DC convert type switch power is universally adopted in fuel dispenser. Diagram 3-13: Structural sketch map of liner vol fuel dispenser tage stabilizing power Diagram 3-14: Structural sketch map of switch stable voltage power adopted DC/DC converter Diagram 3-15: Structural sketch ma fuel dispenser p of switch voltage stabilizing power adopted pulse transformer As an electronic component in fuel dispenser, stable voltage power is easily failed and possibly leads to whole trouble of fuel dispenser once appear doesn’t work. Generally, liner voltage stabilizing power adopts 78 series special voltage stabilizing integrated circuit, such as 7805 and 7812, simple design and convenient maintenance. In Diagram 3-16, a popular liner voltage stabilizing power circuit of fuel dispenser is illustrated. Switch power supply adopted pulse transformer will not introduced here, reference with r fuel dispenser elevant boos when necessary. Diagram 3-16: Circuit diagram of liner voltage stabilizing power These integrated circuits of LM2576, LM4962 AND MC34063A are widely adopted in DC/DC transformer power supply. Intrinsic safety voltage stabilizing power supply in fuel dispenser This kind of direct current is able to employ in flammable and combustible environment only when mounted safety barrier. It also called intrinsic safety voltage stabilizing power supply illustrated in Diagram 3-18. Explosion-proof power supply is only used in explosion-proof box or an atmosphere without explosive gas, including its associated circuit. It is allowed to employ intrinsic safety power in explosive atmosphere, but must in explosion-proof box or an environment without explosive gas. However, its associated circuit is permitted to use in explosive gas atmosphere if meet requirements concerned. The major difference between intrinsic safety power and explosion-proof power is whether install safety barrier.

who is himself a Muslim, argued that it was necessary to seek out and negotiate with the rebellion s leaders, Mr Thaksin s a fuel dispenser ides rejected any such idea. Given General Sonthi s respectability, and the welter of accusations of corruption and abuse of power against Mr Thaksin, m fuel dispenser any Thais may be ready to give him and his fellow plotters a chance to show the sincerity of their promises. But it is noteworthy that even the Nation, a virulently anti-Thaksin daily, has refrained from cheering the coup that brought down its arch-foe. Thai society, it said, believed the generals had done “the wrong thing for the right reason� And if they were slow to return power to the people, it would start to look as though Mr Thaksin were a pretext, not the real reason, for their coup. The millions of Thais who voted Mr Thaksin into office in 2001 and 2005, and who would p fuel dispenser robably have put him back there again, may be forgiven for wondering why their opinions are being disregarded. They are mostly poorer, rural Thais with little prospect of overcoming the might of the armed forces or the slick arguments of Bangkok s sophisticates, who will be relieved to see the back of Mr Thaksin, aghast though they have been to see tanks on the streets of the capital. Mr Thaksin had many deep flaws. The gross conflict of interest between his business affairs and his regulatory and lawmaking powers was among the least of them. Far worse were his constant attempts to pack independent institutions with cronies; his brutal “war on drug dealers�(which was no less than a licence for extra-judicial killings); and his gross mishandling of the southern insurgency. But his critics among Bangkok s chattering classes were a little too ready to sniff at his attempts to do something for the broad mass of poorer Thais, in a way that few political leaders before him had ever done. He may have had his eye mainly on the electoral returns of such policies, but his schemes to offer cheap health care and foster economic development in
