Introduction

The outdoor small integrated DC power HJ048 can be very suitable for low-power network access layer devices to supply power. Long-term backup can be delivered together with batteries. It can be used in systems such as a mobile network indoor distribution system, remote micro base stations, WLAN access layer POE switches, IMS, and FTTH data network access sites.

Waterproof RS-485 communication interface DC power supply system can monitor the real-time condition remotely; its functions include remote signaling, measurement, and control. With multiple functions of battery low discharge voltage protection, output overload protection, high temperature protection, lightning protection, and grounding protection, it has multiple -48V outputs to connect several devices at one time. Thanks to its IP65 enclosure, it supports outdoor installation like wall-mounted installation and pole-mounted installation. It is highly practical with very stable performance.

The advanced communication function supports 4G/5G/GPRS wireless transmission and networking. It is equipped with a locating function and real-time monitoring for uploading working conditions of equipment. Intelligence devices and sensors can be connected at the same time. It features an outdoor DC power supply that is high in efficiency, integration, and expandability for versatility.

Main Features:

High efficiency, high stability, high integration, and expandability, IP65 protection, rugged weatherproof outdoor DC power, is used for the power supply of outdoor layer devices; can be applied to such scenarios as the mobile network indoor distribution system, remote micro base stations, and the WLAN access layer POE switches.
Comprehensive protection: Multiple protection mechanisms are contained therein, such as overload, high-temperature, lightning, and grounding protections. It supports remote control, configuration, and monitoring.
Multiple -48V outputs can power several devices at a time. RS485/ CAN communication interfaces allow for the monitoring of input/output voltage, battery voltage, load current, and the current of battery charge/discharge.
It realizes the function of Bluetooth communication with easy installation. It adopts the near-field wireless communication of Bluetooth and adopts plug-in hanging installation, which can ensure convenience and speed in various scene installations and debugging.
