Dual-input and output power supply for network communication equipment

Abstract

The invention discloses a dual-input and output power supply for network communication equipment. The dual-input and output power supply comprises a dual-input power supply, a transformer T, a converter C and a dual-output power supply, wherein protection modules are respectively arranged at input ends of the dual-input power supply; the dual-input power supply passes through the protection modules and is connected in series with a fuse F1 and a diode assembly in sequence; the output end of the dual-input power supply is in integrated connection with a single power supply; the integrated single power supply is connected to two output circuits; the output circuits are connected with two output power supplies; and the output power supplies are respectively connected with corresponding network communication electric equipment. According to the dual-input dual-output power supply provided by the invention, the problems in the prior art that the operating stability of the single-input single-output power supply is poor, the power supply installation complexity level is high aiming at different communication equipment, errors are easily caused and the like are solved, the dual input power supplies are mutually redundant, normal power supply of the equipment is not influenced when one input power supply fails, and the operating stability and safety of the equipment are ensured.

Description

Technical field [0001] The invention belongs to the technical field of network communication equipment, and specifically relates to a dual-input and output power supply for network communication equipment. Background technique [0002] With the continuous development of communication technology, people are increasingly relying on network communication equipment, which requires the stability of network communication equipment to avoid problems such as network disconnection that affect normal work and life. At present, the power supply for network devices such as IoT smart boxes, wireless gateways, security gateways, Ethernet switches, and outdoor communication equipment is generally single-input, single-input power supply mode. For single-input, there is no backup input power supply, there will be power supply The power outage caused the network equipment to stop functioning, and related supply chain information was interrupted, which affected the stability of the communication eq...

AI Technical Summary

Problems solved by technology

At present, the power supply of network devices such as IoT smart boxes, wireless gateways, security gateways, Ethernet switches, and outdoor communication equipment is generally single-input, single-input power supply mode. For single-input, there is no backup input power supply, and there will be power supply The problem of power outages caused the network equipment to stop operating, and related supply chain information was interrupted, which affected the operation stability of communication equipment. In addition, if the communication equipment is installed in a location that is not easy to repair or remove, once such a single input power supply is damaged, it cannot When working normally, it is difficult to rescue and maintain in time

For single output, industrial IoT sites often contain multiple types of devices. Although these devices are mostly low-voltage power inputs, the required input voltage values ​​are different, so multiple sets of power supplies are required to make the device installation The complexity of the site is high, which increases the difficulty of installation
