The primary use of the High Voltage Gate Interface Board DS200FHVAG1A is to supply cell voltage and SCR gate interference monitoring, these functions occur through the LCI power converter. For each SCR there is one of these boards. This board comes equipped with an SCR Status Circuit LED which will give off a visible indication that there is a blocking presence at the voltage, please note that this lED should be visible whenever the bridge power is activated and will dim when the SCR conduction angle has increased.
The DS200FHVAG1A model has a gate pulse transformer, this specific transformer is a toroidal transformer that is soldered to the board. There is also a fiber-optic transmitter on this board, it is critical to note that if a fiber-optic is not connected to the device then a rubber plug must be inserted into the U1 to prevent debris from accumulating on the lens. Please note that even after an hour of exposure to the lens in particularly dusty environments noticeable pollution can be seen on the lens.
The DS200FHVAG1A model is widely available on the market in both used and new surplus. If you wish to purchase a new or refurbished model, please contact us by email at firstname.lastname@example.org or by phone at (919) 372-8413.
