ETP48400-C3B2 is an embedded power systems that convert AC power into DC power. It supplies –48 V or –57 V constant voltage to telecommunications equipment like Huawei OSN8800 OSN3500 MA5800. The maximum capacity of the ETP48400-C3B2 is 18 kW, and applies to newly built sites as well as capacity expansion and reconstruction of existing sites. The intelligent power distribution unit DCDB48-200-16B/DCDB48-200-16B-XXX and lead-acid battery box DCDB48-400-4C are optional components.

Tech Specs
Technical Specifications
Environment conditions Operating temperature –40°C to +65°C (When the ambient temperature is between –33°C and +55°C, the power system works properly. When the ambient temperature is greater than 55°C and less than or equal to 65°C, the output power is linearly derated to 80%. When the ambient temperature is –40°C, the power system can start properly after AC power is applied.)
