High Reliability - Open and Short Circuit Protection
Versatile weatherproof driver for automotive or general outdoor use (may also be used indoors, but is designed to withstand outdoors use). Can be used for a single-ended or conventional double-ended display. Operates from an automotive battery or any 12-14V DC 2A power supply (not included) and drives up to 10 feet of display. Higher amperage batteries or regulated power supplies will not overdrive this transformer, as it will only draw the current needed to power the load. Output is 4kV at 20ma, at approximately 30kHz frequency. Unbalanced output greatly simplifies install since only one high voltage lead is required and can be only several inches long depending on driver location. The return lead, usually coming from the far end, needs only to be grounded to the auto frame or be a low voltage wire. Fully potted case is 2.75 x 1.75 x 1.25" with a 3.5" aluminum heatsink/mounting bracket, weighing 6 ounces.
If you need a 12V DC power supply, our 12DC/2AR works very well with this transformer.
