ET48150S5E38 48V 150A Hybrid Telecom DC Power System with AC Rectifiers, Solar MPPT Inputs and MC2600 Monitoring

The ET48150-S5E38 is a hybrid 48V telecom DC power system designed for communication sites requiring both utility power conversion and renewable energy access. Unlike a standard rectifier-only power shelf, this system integrates AC rectifier input, three solar MPPT channels, battery protection, DC load distribution and centralized monitoring into one compact cabinet-mounted platform. It is especially suitable for telecom sites where grid power is unstable, solar energy needs to be introduced, or longer backup time is required.

Key Features 48V 150A Hybrid Telecom DC Power System

Hybrid power architecture: Supports both AC rectifier power and solar input, improving site energy flexibility.

Three rectifier positions: The schematic shows Rect1, Rect2 and Rect3, allowing modular rectifier configuration.

Three solar MPPT channels: Equipped with MPPT1, MPPT2 and MPPT3, each connected through an independent solar input breaker.

MC2600 monitoring unit: The controller supports system supervision, alarm collection and operating-status monitoring, with visible input range marked as DC19V–60V.

High-current DC distribution: Multiple output branches are provided for different telecom loads, helping separate critical and non-critical equipment.

Battery protection design: Four independent battery breakers support multiple battery strings and safer maintenance.

LLVD and BLVD control: Load disconnection and battery low-voltage protection help preserve essential communication loads during power failure.

Factory inspection traceability: The unit includes a qualification card and serial number label, indicating factory QC verification before shipment.

Application Scenarios 48V 150A Hybrid Telecom DC Power System

This system is suitable for mobile base stations, remote telecom shelters, microwave transmission sites, fiber access nodes, rural communication networks, solar-assisted telecom cabinets, railway and highway communication facilities, security monitoring stations and off-grid or weak-grid communication sites.
