Description: 19-inch 1U Rack-mounted 48V Industrial Telecom Power System
The EMERSON SS6048R2P3 is a high-performance embedded rack-mount DC power supply system. Adopting standard 19-inch 1U compact chassis design, it is developed for 48V DC power supply in telecommunication rooms, industrial automation and small data centers.
Equipped with high-frequency soft-switch rectifier technology, this power system features high efficiency and high power factor. It accepts single-phase AC input from 176V to 264V AC. Rated output: 48VDC, 60A, total power 2880W. Output voltage is adjustable between 42~58VDC with voltage regulation accuracy ≤±0.5%.
Comprehensive protection functions are integrated: OVP overvoltage protection, OCP overcurrent protection, OTP over-temperature protection and short-circuit protection with automatic recovery after fault removal.
It supports battery charging & discharging management, including float/boost charging and low voltage load disconnect, suitable for long-term unattended operation. Stable full-load operation at 0~45℃. Widely applied in communication base stations, transmission equipment, industrial DCS & PLC systems, security control rooms and mini data centers.
Protection and Management Functions
Basic Electrical Protection
OVP Output Overvoltage Protection, OCP Output Overcurrent Protection, OTP Overtemperature Protection, Output Short Circuit Protection
After faults are resolved, power supply can be automatically restored without the need for frequent manual resets
Battery Management
Supports automatic switching between equalization charging and floating charging for lead-acid batteries
Has a battery low-voltage cut-off (LVD) function to prevent deep battery discharge damage
Compatible with base stations / data center backup power supply for uninterrupted power supply scenarios
Status Monitoring
Equipped with a power supply operation indicator light and fault alarm contacts, which can be connected to the data center environmental monitoring system for remote viewing of operation status
