New TDK-Lambda EZA2500W-32048 bi-directional DC-DC converter
TDK Corporation is introducing the EZA2500W-32048 TDK-Lambda brand bi-directional DC-DC converter model to its EZA series. The extended high voltage range now covers 260 to 400V DC and the lower voltage 36 to 65V DC. The operating temperature has been increased to -10 to +50degC. Double-sided protective board coating and long-life dust-resistant fans have also been included.
Designed for energy storage systems with rechargeable batteries, this 2500W digitally controlled, compact 1U power supply can seamlessly change conversion direction from high-voltage DC sources, powered by solar or wind, to 48V DC batteries and vice versa. Other applications include lithium-ion battery testing as well as the use of regenerated energy from robots, cranes, autonomous ground vehicles and lifts. The EZA2500 can be used to replace large power resistors currently used for lift braking and use that previously dissipated energy to charge batteries. That stored energy can be used to either provide peak power for high torque demands or as battery back-up for power cuts.
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 "droop mod" current share. 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 3,000V AC, grid to ground 2,000V AC and battery to ground 500V AC.
The dimensions for the EZA2500 are 43.6mm (1U) high, 423mm wide and 400mm deep. 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.
