The EZA series of 2.5kW<\/a> to 11kW isolated bi-directional DC-DC converters<\/a> is designed for energy storage systems with rechargeable batteries. The compact 1U high power supply is digitally controlled and can automatically change conversion direction from high voltage, grid sources (320Vdc), powered by solar or wind, to 48Vdc or 240Vdc batteries and vice versa. This means that when grid power is not available, the converter will seamlessly transition to drawing stored energy from the batteries to deliver DC power back to the grid without interruption in power.<\/p>\r\n\r\n\r\n\r\n

Other applications include lithium-ion battery testing, as well as the recovery of regenerative energy from robots, cranes, automated guided vehicle systems (AGVS) and lifts. That stored energy can then be used to either provide peak power for high torque demands or as battery back-up during power cuts.<\/p>\r\n\r\n\r\n\r\n

The output voltage and current can be programmed and monitored using the RS-485 communications port. Multiple units can be operated in parallel by using the RS-485 interface to set units for \u201cdroop mode\u201d current share<\/a>. Alarm signals are also accessible, as well as remote on\/off and under\/over voltage functionality. The high voltage (grid) to low voltage (battery) isolation is 3,000Vac, grid to ground 2,000Vac and battery to ground 500Vac.<\/p>\r\n\r\n\r\n\r\n

The use of digital control techniques, SiC (Silicon Carbide) MOSFETs and low loss core technology allows the converter to operate with efficiencies of up to 96%. All models in the EZA series are certified to the IEC\/EN\/UL 60950-1 and IEC\/EN\/UL 62368-1 safety standards with CE marking for the Low Voltage, EMC and RoHS Directives. A five-year warranty is standard.<\/p>\r\n\r\n\r\n\r\n
