ES Series 1U 48V DC Rackmount Rectifier & Battery Charger (20–60A)
48V DC Rackmount Rectifier and Battery Charger for Telecom Power Systems
The ES Series 1U Rackmount Rectifier and Battery Charger provides regulated 48V DC power with 20A, 30A, 40A and 60A current configurations for telecommunications, data centres, networking and industrial applications.
The ES Series is a rackmount switch-mode DC power supply designed to deliver regulated 48V DC output within a compact embedded power system. The ES1U-4860 model provides a nominal 48V output with an adjustable operating range of 42V to 60V, supporting a selection of output current configurations.
Developed for telecommunications, data centres, local area networks, servers and industrial processes, the system combines rectifier modules with an STM-III monitoring module. Its monitoring functions include battery management, low-voltage detection, ambient temperature detection and an RJ45 Ethernet interface.
The compact 1U design allows installation in a 19-inch equipment rack. Electrical protection functions, load and battery distribution connections and system monitoring features support the management of DC power requirements.
