Industrial Active PoE to Passive PoE Converter | 48V to 24V Gigabit Step-Down Adapter | OEM / ODM
Seamlessly Integrating Legacy 24V Passive PoE Hardware into Modern Active 802.3af/at Managed Infrastructures
The Active PoE to Passive PoE Converter bridges the gap between legacy 24V passive equipment and modern standard PoE switches, allowing system integrators to seamlessly integrate 24V outdoor wireless devices into standard IEEE 802.3af/at (48V–56V) active network environments. By utilizing standard active PoE switches to centralize power management, this converter eliminates the need for standalone 24V power injectors and costly remote AC socket installations. Engineering teams can run standard Ethernet cables up to 100 meters at high voltage (48V) to avoid line voltage drops, stepping down to 24V locally right at the device. This delivers maximum cabling flexibility, protects existing hardware investments, and significantly reduces overall labor and material deployment costs.
Target Application Scenarios & Flexible Deployment
Designed to simplify infrastructure upgrades and streamline field installations for global system integrators:
Legacy 24V Network Integration
Allows existing 24V passive outdoor CPEs, PtP wireless bridges, and APs (such as Ubiquiti airMAX and MikroTik) to connect directly to modern managed 802.3af/at switches without replacing working hardware.
Flexible & Low-Cost Cabling
Uses a single standard Cat5e/6 cable for long-distance 48V transmission, converting to 24V locally at the terminal node to eliminate line attenuation and save on high-voltage AC trenching and wiring costs.
Centralized Power Management
Replaces messy wall-plug injectors with centralized active PoE switch management, enabling remote port rebooting, UPS battery backup, and cleaner outdoor cabinet layouts.
Key Product Features & Technical Advantages

IEEE 802.3af/at Input
Fully compatible with standard IEEE 802.3af/at active PoE switches, performing precise hardware handshake recognition before receiving 48V–56V power safely.

Regulated 24V Output
Steps down high voltage to a regulated 24V Passive PoE output (Mode B: Pins 4,5+ / 7,8-), providing safe and continuous power for outdoor wireless APs and CPEs.

Waterproof Output Joint
Features a dedicated IP66 waterproof connector assembly on the 24V PoE output side to ensure secure and sealed connectivity leading to external outdoor network devices.

Zero External AC Wiring
Operates entirely on network bus power with zero configuration needed. Completely avoids installing remote AC outlets, wall adapters, or heavy power boxes.

Durable ABS Enclosure
Constructed with a high-impact, flame-retardant ABS plastic casing that combines lightweight portability with long-lasting structural durability for field installations.

Full Gigabit Throughput
Delivers full-duplex 10/100/1000Mbps wire-speed data passthrough without bandwidth throttling, ensuring zero packet loss for high-speed wireless backhaul.

-30°C to 75°C Endurance
Engineered to sustain continuous, reliable operation across an extended ambient operating temperature range from -30°C to +75°C, ensuring stable performance in extreme cold or hot environments.

Surge & ESD Protection
Integrated with TVS surge suppressors and ESD clamping diodes on port interfaces to guard connected sensitive wireless equipment against transient electrical spikes.
Desktop & Endpoint Connectivity Solutions
Eliminate 24V voltage drop and fit into tight spaces: Connect standard 48V PoE switches to remote wireless CPEs and access controllers via an ultra-compact inline pigtail converter with RJ45 input port.

Optimized Deployment Scenarios
- 1. Long-Distance 24V Power via 48V Backbone Overcomes the <50m distance limit of direct 24V passive PoE. The upstream network carries low-loss 48V active PoE up to 100m via standard Ethernet cable to the converter’s RJ45 input port, which then steps down to regulated 24V only at the final 18cm. This architecture guarantees full voltage delivery to remote Ubiquiti/MikroTik CPEs and door controllers without costly cable upgrades.
- 2. Direct Plug-in for Pole-Mount & Door Header Spaces Measuring just 80×30×23.5mm with an integrated 180mm RJ45 pigtail, the unit plugs directly into the device port inside cramped pole-mount enclosures, AP bases, or door header cavities. The compact desktop-grade form factor eliminates bulky adapter bricks and patch cables that cannot fit in confined installation spaces.
- 3. Desktop & Weak-Current Box Plug-and-Play Designed for indoor desktop deployment or weak-current panel integration. Simply connect an Ethernet cable from any standard 802.3af/at PoE switch or injector to the converter’s RJ45 female input port, then plug the 180mm pigtail directly into your 24V device. Zero configuration, zero external power, and no tools required for instant 24V passive PoE conversion.
