The new EZA11K-320240 bi directional DC-DC converters are suitable for use with energy storage systems. With an 11kW rating, this 1U high product will operate off a 240 – 400Vdc source from a high voltage grid. It also provides 150 – 300Vdc for charging lithium ion batteries. When grid power is unavailable, it will transition seamlessly to drawing stored energy from the batteries to deliver DC power back to the grid. The EZA11kW is suitable for use in peak demand storage systems, emergency back-up power and regenerative braking.

The compact EZA11kW measures just 43.6mm high, 422.8mm wide and 530mm deep. Connect up to five converters in parallel for larger scale systems. Use of digital control techniques, SiC (Silicon Carbide) MOSFETs and low loss core technology enables efficiencies of up to 95%.

An RS-485 serial communication interface allows remote adjustment of the voltage and current settings, battery / grid under and over voltage levels and monitoring of alarm signals. Serial connection of multiple converters is possible.

The EZA11kW has an input to output isolation of 2,200Vac, an input/output to ground isolation of 2,000Vac and 400Vac for signals to ground. Safety certifications include UL60950-1, CSA60950-1, EN60950-1 and the product is CE marked to the Low Voltage and RoHS2 Directives. The product carries a five-year warranty.
