eSure™ Rectifiers
Ultra high efficiency of 96.5% is achieved with the eSure R48-2000e rectifier. eSure rectifiers from Vertiv deliver the most reliability
and highest efficiency in the industry, reducing power consumption and lowering operation cost.

Environmental Endurance

Great output power at high temperatures

NetSure 502 rectifiers deliver high output power in relation to ambient temperature conditions, making them especially suitable for
high-temperature environments. In a system with rectifiers operating at 65 °C, the output is still a minimum 80% of full power.
Extremely wide AC voltage range window
The AC voltage input range vs. rectifier output is another extraordinary feature of this small system. The rectifier’s input voltage
ranges from 85 VAC to 300 VAC. Between 176 VAC to 300 VAC, the output is 100% of full power.
