Emerson PS48120-2/1800-Y4 Y5 DC Power Emerson R48-2000e R48-1800A R48-1800 DPC48-3 M520S

Product Description

The PS48120-2/1800 -Y4 Y5 is a one-cabinet DC power system integrated with AC and DC distribution units, providing up to 120A for -48VDC.

The PS48120-2/1800 power system comprised of AC distribution units, DC distribution units, rectifiers (R48-1800A, R48-2000e : 58V/30A), supervision unit (M500S) and cabinet. The system can provide maximum 120A output current and very suitable for radio base stations, small telecom exchanges, fiber repeaters and satellite communication stations applications.

Features

The rectifier uses the active Power Factor Compensation (PFC) technology, raising the power factor to 0.99
Wide AC input voltage range. 85V ~ 300V for manual switching system
The rectifier uses soft switching technology, raising the efficiency to 91%
High power density
Rectifiers are hot pluggable. It takes less than 1min to replace a rectifier
Two over-voltage protection methods are optional: hardware protection and software protection. The latter one also has two optional modes: lock-out at the first over-voltage and lock-out at the second over-voltage
Perfect battery management: The management functions include the load low voltage disconnection (LLVD) (optional), battery low voltage disconnection (BLVD), temperature compensation, auto voltage regulation, stepless current limiting, battery capacity calculation, and on-line battery test
Up to 200 pieces of historical alarm records, and 10 sets of battery test data records
Network design: Providing multiple communication ports (such as RS232, modem and dry contacts), which enables flexible networking and remote monitoring
Perfect lightning protection at both AC side and DC side
Complete fault protection and fault alarm functions

System Features

Embedded batteries, space saving
Full front access for easy installation and maintenance
Wide input voltage range of 80 to 300 Vac
Rectifier with wide working temperature range: -40°C~70°C
DSP control technologies effectively increases rectifier power density
Smart battery management effectively protects the battery
Perfect lightning and surge protection at AC side, DC side and signal interfaces
Hot-swappable of rectifier and controller modules, realizing quick and easy online maintenance
Optional DC/DC converter modules, providing 6V, 12V and 24V DC output

System Model

PS48120/1800-Y4: Two-way AC manual switch, no user AC output
PS48120/1800-Y5: Two-way AC automatic switch, with user AC output

Applications

3G, GSM, CDMA mobile base stations
Small and medium exchanges, rural
telephone and access networks
Transmission relay stations
Communication equipment rooms
and wireless base stations of railway
intermediate stations

Benefits

Ultra-low radiation. With advanced EMC design, the rectifier meets international standards such as CE and NEBS. Both the conducted and radiated interference reach Class B
The rectifier safety design complies with UL, CE and NEBS standards
