APC Rack Automatic Transfer Switches (rack ATS) provide reliable, redundant rack mount power to single-corded equipment.
What is a DIAC - Tutorial. - the DIAC, Diode AC bi-directional switch is widely used with TRIACs to improve operation of alternating current power switching systems. The DIAC is a full-wave or bi-directional semiconductor switch that can be turned on in both forward and reverse polarities. The DIAC gains its name from the contraction of the words DIode Alternating Current. The DIAC is widely used to assist even triggering of a TRIAC when used in AC switches. DIACs are mainly used in dimmer applications and also in starter circuits for florescent lamps. Circuit symbol
