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. The EZA11kW is designed for use in cost-saving peak demand
storage systems, emergency back-up power and recycling waste motor braking energy.
Supports parallel operation for increased performance
The compact EZA11kW measures just 43.6 mm high, 422.8 mm wide and 530 mm deep, and has the highest power
density for an isolated bi-directional converter in the industry. Up to five converters can be connected in
parallel for larger scale systems.
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 95 per cent.
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 2,200 Vac, an input/output to ground isolation of 2,000 Vac
and 400 Vac 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.
