Embedded Power Supply

Embedded −48 V DC switching power system designed to supply critical telecommunications equipment. With a maximum output current of 300 A and a total capacity of 18 KW, it integrates AC/DC distribution, rectifier modules, and intelligent monitoring in a compact chassis with six module slots, providing a complete and scalable power solution.

Efficiency up to 97%, reducing opex.
Supports SNMP/Modbus protocols, Ethernet/RS485 interfaces, and provides a web interface.
Pre-configured for telecom base stations.
Features peak shaving, load shifting, energy arbitrage, battery charging, and hybrid power control functions.
Supporting solar converter installation.
