Direct Device-Mount Active to Passive PoE Converter | 802.3af/at to 24V Gigabit Plug-and-Play Adapter

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 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.

Target Application Scenarios

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 Compatibility Issues Between 802.3af/at Active PoE Switches & 24V Passive Devices

Q1: Why won't my standard 802.3af/at PoE switch power a 24V passive CPE or wireless bridge?

Standard IEEE 802.3af/at PoE switches require an active 48V hardware handshake before supplying power. Because 24V passive devices (such as Ubiquiti, MikroTik, or Cambium wireless APs) lack this active handshake circuit, the switch detects no valid signature and refuses to output power, resulting in no boot-up. The PSE200-ACP24 adapter completes the active handshake with the switch and steps down the voltage to supply regulated 24V passive PoE seamlessly.

Q2: Is the PSE200-ACP24 converter compatible with Ubiquiti airMAX, MikroTik, and 24V IP cameras?

Yes, the PSE200-ACP24 is fully compatible with all legacy 24V passive PoE terminals requiring Mode B (Pins 4,5+ / 7,8-) power delivery up to 12W–24W. It works seamlessly with Ubiquiti airMAX (NanoStation, Rocket, Bullet), MikroTik RouterBOARDs, outdoor Wi-Fi CPEs, and 24V access control terminals, allowing you to manage all devices centrally using a standard 48V/56V active PoE switch.

Q3: Does this 48V to 24V PoE converter support 1000Mbps Gigabit data speeds and Mode B pinouts?

Yes. The PSE200-ACP24 supports full-duplex 10/100/1000Mbps Gigabit Ethernet pass-through across all 4 pairs (1/2, 3/6, 4/5, 7/8). Power is output via standard Passive PoE Mode B (Pins 4,5 Positive / Pins 7,8 Negative). It ensures high-bandwidth throughput without signal degradation, latency, or packet loss for remote HD cameras and high-speed wireless bridges.

Q4: How should the PSE200-ACP24 be installed for outdoor wireless bridge deployment?

The PSE200-ACP24 features a waterproof gland connector on its 24V PoE output side, designed to connect directly to outdoor CPE cables. However, since its 48V RJ45 input jack is non-waterproof, the converter main unit should be placed inside an IP66/IP67 outdoor junction box or under sheltered eaves to protect against direct rainfall and water ingress.

Q5: Can network distributors request custom branding, modified pinouts, or OEM/ODM packaging?

Yes. As a direct OEM/ODM network manufacturer in Shenzhen, China, we offer complete white-label customization for global distributors and system integrators. Options include custom housing colors, laser logo printing, bespoke cable lengths, Mode A/B pinout adjustments, and full OEM packaging. The board layout is fully certified for CE, FCC, and RoHS compliance.
