Batteries Monitoring and Management Embedded Switch Mode Power Supply
Introduction
TEP 400H2/48 is a DC distribution unit which be used for solar / diesel / grid hybrid scenarios. It contains up to 8 pieces of HFSM modules, 4 pieces of solar modules, DC power distribution board controller SC501 etc. The function is collecting multiple power input from solar, diesel, and grid, and converts it to DC output for loads.
Features
- PFC technique features the system high efficiency, energy-saying
and up to 0.99 power factor
- Supports hot-swap for modules of HFSM, MPPT
- Can be forced power on by pressing the battery switch when only
the battery works
- Detects BLVD & LLVD signals, and detects signals of battery
and load loop disconnection
- Integrated SPD to provide reliable protection for DC power,
monitoring and communication ports
- Detects current signals of batteries, loads and other energy
inputs
- Batteries monitoring and management enables backup batteries well
maintained
- Management priority: solar > grid > battery > DG
Applications
- Fiber optic network
- Access network
- Transmission equipment
- Mobile communication
- Satellite communication ground station
Scenarios
- Solar / diesel / grid hybrid system
