Direct Attachment to Terminal Devices—Eliminating Extra Patch Cords for Space-Saving 24V Step-Down

The PSE202-ACP24 Direct Device-Mount Active to 24V Passive PoE Converter delivers an innovative, direct-plug solution for integrating 24V passive PoE hardware—such as Ubiquiti airMAX, MikroTik RouterBOARDs, outdoor CPEs, and access control terminals—into standard IEEE 802.3af/at (48V–56V) active network switch infrastructures. Featuring a standard RJ45 female input port and an integrated male RJ45 output plug, this compact converter connects directly into the Ethernet interface of the end device. By eliminating the need for an additional patch cord between the converter and terminal device, the 48 to 24v poe converter PSE202-ACP24 reduces field connection points, lowers material inventory costs, and simplifies cabinet wiring. Built in a compact ABS molded housing, it receives standard 48V active PoE transmission over network cables up to 100 meters, stepping down to regulated 24V DC / 1A passive output locally at full Gigabit wire speed.

Typical Application Scenarios

  • 1. Standard Active Switch to 24V Wireless Bridge Conversion Safely connect 24V passive wireless CPEs or point-to-point (PTP) bridges to an enterprise IEEE 802.3af/at active PoE switch. The PSE200-ACP24 negotiates power safely via active 802.3af/at handshake and steps down the voltage to a regulated 24V output (Mode B: Pins 4,5+ / 7,8-), protecting legacy 24V wireless gear from high-voltage damage while maintaining full Gigabit backhaul.
  • 2. Protected Outdoor Cabinet & Enclosure Deployment Because the non-waterproof PoE input port cannot be exposed directly to open rainfall, the unit is intended for placement inside outdoor waterproof junction boxes, equipment cabinets, or sheltered eaves. Its output side features a dedicated waterproof connector to ensure a sealed connection for the downstream cable extending out to remote wireless APs.
  • 3. Extended Operating Temperature Resistance (-30°C to +75°C) Powered entirely via the incoming Ethernet bus line with zero external AC power required, the converter withstands harsh environmental temperatures ranging from -30°C up to +75°C inside outdoor enclosures, making it ideal for year-round operation across unheated industrial sites and extreme weather conditions.

Frequently Asked Questions (FAQ)

 

Solving 24V Passive PoE Compatibility, Voltage Drop & Space Constraints with Inline Pigtail Conversion

Q1: Why can't I just use a standard 24V passive PoE injector instead of this active-to-passive converter?

A standard 24V passive injector forces 24V onto the Ethernet cable from the start, suffering severe voltage drop beyond 30–50 meters and risking device underpowering. This converter accepts 48V active PoE from your switch over 100m, then steps down to regulated 24V only at the final 18cm via the integrated pigtail. You retain centralized 48V PoE management while guaranteeing full voltage delivery to remote CPEs or access controllers without mid-span repeaters.

Q2: Does this converter plug directly into my PoE switch port?

No. This model’s RJ45 male pigtail is the 24V output for direct connection to CPEs, cameras, or access controllers. Its input requires an Ethernet cable from your switch. For a version with an RJ45 male input that plugs directly into IEEE 802.3af/at PSE ports, please select model PSE204-ACP24.

Q3: What is the exact 24V passive PoE pinout, and does it support Gigabit data?

The converter outputs standard Passive PoE Mode B: Pins 4,5 positive (+) and Pins 7,8 negative (-), with data on Pins 1,2,3,6. It supports full-duplex 10/100/1000Mbps Gigabit passthrough across all four pairs with zero signal degradation. This pinout is natively compatible with Ubiquiti airMAX, MikroTik SXT/LHG/RB series, Hikvision/Dahua 24V access controllers, and virtually all 24V passive PoE Mode B devices.

Q4: Can I install this PoE to 24v passive adapter outdoors on a pole or in direct rain?

The adapter body is not waterproof and must be installed inside a weather-protected enclosure such as a pole-mount junction box, AP base housing, door header cavity, or indoor weak-current panel. Only the downstream 180mm pigtail connection to the outdoor CPE may be exposed. For fully waterproof outdoor deployments requiring direct rain exposure, please refer to our industrial-grade PSE200-ACP24-WP model with sealed output connector.

Q5: Why choose this desktop/pigtail version over bulkier industrial PoE converters?

At just 80×30×23.5mm with an integrated 180mm pigtail, this unit is engineered for space-constrained endpoints where traditional brick-style adapters or DIN-rail modules simply won’t fit. It eliminates the need for separate patch cables inside cramped CPE enclosures or door headers, reducing installation time and failure points. For server racks or industrial cabinets with ample space and rail mounting, our standard industrial version may be more appropriate.

Q6: Do you offer custom pigtail lengths or OEM branding for distributors?

Yes. As a direct manufacturer, we provide full OEM/ODM services including custom pigtail lengths (50cm, 1m, etc.), laser logo engraving, bespoke housing colors, and tailored packaging. All units are CE/FCC/RoHS certified. Contact our sales team with your project specifications for MOQ and lead time details.
