Introduction:
Outdoor Integrated DC Power Supply: supplies power to the low-power network access layer equipment; with a battery, it may provide long-term backup when equipped. It can be extensively used in mobile network indoor distribution systems, mobile network remote micro base stations, WLAN access layer POE switches, IMS, FTTH data network access sites, and many more. This controller is connected through an RS-485 communication interface, which can real-time monitor the working condition. It has remote signaling, remote measurement, and remote control functions. It also has low discharge voltage protection of the battery, output overload protection, high-temperature protection, lightning protection, and grounding protection. Due to multiple outputs of -48V, several devices can be powered at the same time. The enclosure is designed for outdoors, according to the IP65 protection level. It supports wall-mounted and pole mounting; the whole performance is stable and practical.
The communication function of the power supply supports 4G/5G/GPRS wireless transmission and networking, positioning function, and real-time monitoring, which can upload the operating status of the device. It also supports the connection of various types of intelligent devices and sensors. This product provides not only high performance, high integration, and high stability but also excellent scalability.

The HJ048 power system supports multi-module parallel expansion, and battery modules also support parallel expansion. The maximum configuration is 4PSU+4BAT (4 power supplies and 4 batteries), supporting up to 12 power distribution channels. The expansion method involves using the accompanying cascade cable to cascade the battery module's charge/discharge port to the power module's charge/discharge port, then cascading the communication ports.
