MikroTik PW48V-12V85W ±48V Telecom PSU CCR r2

The MikroTik PW48V-12V85W is a purpose-built open-frame DC-DC power supply module designed to bridge the gap between standard telecom ±48V DC power infrastructure and MikroTik's Cloud Core Router (CCR) platform. It enables CCR devices — from revision r2 onwards — to be powered directly from the ±48V DC power systems commonly found in telecommunications facilities, data centres, ISP points of presence, and carrier-grade equipment rooms, eliminating the need for separate AC-DC conversion equipment.

±48V Telecom Input Compatibility

Although designed specifically for standard ±48V DC telecom power, the PW48V-12V85W accepts a wide input range of 36V to 57V at up to 3A, providing compatibility with real-world telecom power plant variations including batteries operating under load or at float voltage. This makes it a reliable and flexible power source across a wide range of telecom and ISP infrastructure environments.

12V / 7A Regulated Output

The module delivers a clean, regulated 12V output at up to 7A — providing up to 85W of output power — matching the power input requirements of compatible CCR routers. This makes it a direct, purpose-matched replacement or supplementary power solution for CCR installations in telecom-powered environments.

Open-Frame Design

The PW48V-12V85W uses an open-frame (IP00) form factor, designed for internal installation within equipment enclosures or racks where the CCR router is housed. This compact form factor is standard in professional networking and telecom equipment, allowing the PSU to be fitted directly inside the chassis without requiring additional enclosed housing.

Ideal Use Cases

The PW48V-12V85W is the go-to power solution for network engineers and ISPs deploying MikroTik CCR routers in telecom facilities, central offices, PoPs, and co-location environments where ±48V DC is the dominant power standard. It eliminates the need for separate AC-to-DC rectifiers or step-down converters, streamlining installation and reducing power conversion losses.
