1U Ultra-thin Telecom DC Power System
,Dual AC Input Embedded DC Power Supply
,Hot-swap Modular Rack Mount DC Power Cabinet
The E merso n EPS30-4815AF is a professional 1U rack-mount embedded DC power system tailored for telecom equipment and FTTX OLT devices. It supports dual AC input of 100–120V and 200–240V, converting alternating current into stable 48V / -53.5V DC power. This unit offers two output current options (15A and 30A) with a rated output power of 1500W, and adopts a forced air cooling design for reliable heat dissipation.
Equipped with the GERM4815T rectifier module and EPMU03 monitoring module, it features hot-swap functionality, multi-circuit power distribution, and battery access management. Compact in size, high in efficiency, and easy to maintain, it is widely compatible with mainstream OLT models such as H uawei MA5680T and ZTE C320, making it a preferred power solution for indoor machine rooms and communication access networks.
