Overview Specifications Resources

Input voltages

110 V, 48 V, 24 V and 12 V

Output voltages

48 V, 24 V and 12 V

High power density

The 3G architecture is reliable, power dense and compact. The high-power density allows as little as 1U of rack space to be occupied by power, therefore maximizing space available for your telecom and industrial equipment. Multiple parallel units allow for high power systems within compact and dense housings, and they also allow for active redundancy.

Versatile solution for you

The MCU-3G products are suitable for integration within Eaton’s DC Rack Power Systems to provide multiple voltages, earth polarity and DC distribution within the same system

Higher reliability

The MCU-3G converter incorporates a combination of leading-edge high frequency switch mode technology for a flexible and efficient DC power conversion source, with dual thermostatically controlled fans which further contributes to its high overall reliability. The MCU-3G is designed to operate with the Eaton SC300 system controllers in any of the versatile Access Power Solutions. The controller offers highly advanced control and monitoring features including Smart Alarms – a configurable logic for automated site energy control
