GDK2001 Non-Isolated Bidirectional Power Board is a unit that, when fed with city power line gets fed with (28VDC-32VDC) Input. When the city line is out, it gets fed with battery continuously with (20VDC-34VDC) Input. When supplied from AC / DC converter, it charges the batteries according to the healthiest smart battery charging protocol. The unit adjusts the percentage zone that these modes will occupy during the charging time according to the battery voltages.

The built-in microprocessor runs an embedded software that collects card-related information. It can send card-related information or receive specific commands via the communication interface.

Output;
• 32V to 28V, regulated by AC / DC converter or DC / DC Battery Charger,
• 5,4V BUS voltage regulated by GDK,
• 48 VFAN voltage, regulated by GDK.
