PoE switch output 15V

A 15V PoE switch provides 15 volts DC over Ethernet to power compatible devices, typically delivering up to 15W per port.

Key Specifications

• Output Voltage and Current: Standard 15V DC output, often with 1A per port, providing up to 15W of power per device .
• Port Configuration: Common models include 24 RJ45 ports for data and PoE, plus 2 uplink ports for network expansion .
• Data Speed: Many 15V PoE switches support 10/100 Mbps per port, with auto-negotiation and MDI/MDIX support for easy connectivity .
• Total Power Budget: Switches can supply a total of 250W across all ports, ensuring multiple devices can be powered simultaneously .

Applications

15V PoE switches are suitable for powering devices such as:

• IP cameras for surveillance
• Wireless access points
• Video intercom systems
• Embedded network devices and small switches

Safety and Protection

High-quality 15V PoE switches include:

• Overvoltage and overcurrent protection
• Short-circuit and overload protection
• Temperature monitoring for stable operation

Passive vs Active PoE

• Passive PoE: Delivers a fixed 15V without negotiation; devices must support 15V input.
• Active PoE (IEEE 802.3af/at): Negotiates voltage and current with the powered device, providing safer and standardized power delivery. Some 15V switches are passive, so ensure device compatibility .

Summary

A 15V PoE switch is ideal for powering low-voltage network devices while transmitting data over a single Ethernet cable. When selecting a switch, verify the device voltage requirements, port power capacity, and whether the switch is passive or active PoE to ensure safe and reliable operation .
