BCR50GM-12L new way SCR SCR BTA412Y, thyristors BCR50GM :( sign and return your goods issue) before the sale of goods, each of us have been carefully checked and tested. When goods delivered, please consignee (or collection of persons) before the carrier must respect SCR BTA216, on the spot to see the packaging is intact, and you purchase goods inventory, and respect their rights, once the sign, it means you recognized the carrier intact to give you the stuff. Loss because they do not check the signature on the receipt caused, according to the rules of Paypal, the restaurant is not responsible for all the losses borne by the buyer. Thanks! So, please be sure to check before leaving intact! Because of the carrier to avoid causing unnecessary misunderstanding and losses to buyers and sellers. SCR triac A1 between the first and second anode anode A2, regardless of the applied voltage polarity is forward or reverse, as long as the control electrode G and the first anode A1 plus a polarity between different trigger voltage , you can trigger the conduction low resistance state. In this case A1, A2 between the pressure drop is about 1V. Once a triac is turned on, even if the loss trigger voltage, can keep the conductive state. Only when the first anode A1, A2 second anode current is reduced SCR BTA212, less than maintaining the current or A1, A2 when the voltage polarity between change and no trigger voltage, triac was truncated, this time only to re-add trigger voltage before conduction.
