Industrial DC Power System – 45U

The Eaton Industrial DC Power System is the ideal low cost, yet sophisticated, d.c. power system package for medium industrial applications that require an efficient, reliable and flexible 24 V or 48 V d.c. power back-up solution. With a modular, expandable system and an intelligent system, the system is designed to operate in demanding environments found in your industrial applications.

Input Voltage
240 Vac
Capacity-Rectifiers
24 V: up to 6 x rectifier modules (APR24-3G)
48 V: up to 6 x rectifier modules (APR48-3G)
Capacity-Batteries
24 V: 6 x 24 V strings of 150Ah
48 V: 3 x 48 V strings of 150Ah

Modular and expandable

The system is provided with an industrial grade 45U cabinet and will typically be fitted with the necessary infrastructure to grow from 1.8kW/55Ah to 8.9kW/450Ah. Options exist for dual A+B infrastructure and battery expansion.

Hot swappable plug-in rectifiers

As your load requirements grow, simple addition of plug-in rectifiers means your DC power requirements are always met. Additional battery cabinets could be added to increase battery back-up time. The 48 V system is based on the APR48-3G whereas 24 V system uses APR24-3G modular switch mode rectifiers. To ensure optimum battery charging and detailed monitoring both systems are compatible with the SC300 microprocessor-based controller.
