MikroTik Hot Swap -48V DC Telecom Power Supply
Features: Hot Swap -48V DC telecom power supply (PW48V-12V150W). Designed for use with CCR1072, enabling replacement of a current supply to support -48V installations.
Best for: Engineers upgrading CCR1072 setups needing minimal downtime during power supply changes. This unit is selected for its intended telecom compatibility and hot-swappable design.
Caution: Ensure proper mating with existing rails and observe -48V installation procedures to avoid accidental retraction of live power.
HPMN 48V 3A Power Supply
Features: 48V DC power supply, input 100-240V, output 48V DC up to 3A (144W max). Indoor use only. Compatibility with 5.5×2.5mm and 5.5×2.1mm jacks; inner-positive polarity. Not suitable for lithium battery charging or outdoor use without protection.
Best for: Small to mid-size CCTV cameras, PoE switches, and similar devices needing up to 3A at 48V indoors.
Caution: Do not overload; exceeding 3A can damage the supply. Not waterproof.
VAYALT 48V 25A 1200W DC Switching Power Supply
Features: Universal AC input 110V/220V; adjustable 48V ±10% output; maximum peak 1200W, 25A. Intelligent cooling with a temperature-controlled fan and upgraded heat sink. Aluminum casing with built-in wiring, multiple device connections, copper terminals.
Best for: Industrial, CCTV, or multi-device setups requiring higher current and robust cooling for stable operation.
Caution: Variable load and peak power considerations mean not all loads can tolerate the 1.25x or 2x peak power guidelines; plan for resistive vs motor loads accordingly.
MikroTik PW48V-12V85W 48V Telecom Open Frame
Features: Open-frame 48V telecom power supply, 2-pin input, voltage 48-48V, 3A.
Best for: Open-frame telecom deployments needing reliable -48V installations with compact form, especially in retrofits or space-constrained racks.
Caution: Check compatibility with your specific MikroTik devices and ensure proper open-frame mounting and enclosure clearance.
MikroTik PW48V-12V85W ±48V Open Frame Power Supply
Features: ±48V DC telecom open frame with 12V 7A output, designed for new “r2” revisions of Cloud Core Routers. Quick replacement for existing supplies to enable -48V installations.
Best for: Networks using Cloud Core Router r2 revisions that require reliable -48V supply with a stable 12V auxiliary output.
Caution: Ensure the -48V rails are compatible with the specific router revision and wiring scheme to avoid power misalignment.
Buying Guide
Key considerations for selecting a 48V DC telecom power supply include compatibility with your devices, form factor, and environmental requirements. Below are practical questions to guide your decision.
- What is the required voltage regime? – Do you need -48V only, or ±48V with a 12V auxiliary output?
- What is the maximum current/load? – Do you expect up to 2A, 3A, or more than 5A in your setup?
- Open-frame vs enclosed? – Is space in a rack or enclosure available for an open-frame supply, or is a sealed unit preferred?
- Indoor vs outdoor use? – Is weatherproofing required or is indoor placement sufficient?
- Heat and cooling? – Does the install require an intelligent cooling system or passive cooling will suffice?
- Safety and compatibility notes? – Are there restrictions about lithium batteries or special polarity that must be observed?

FAQ
- Q: Can I mix -48V and 48V power supplies in the same rack? A: This depends on device polarity and common rails. Ensure compatible wiring and no cross-connection between rails.
- Q: Are these supplies suitable for outdoor deployment? A: Most listed options are indoor-only unless explicitly rated waterproof or weatherproof.
- Q: What does “open-frame” mean for telecom power supplies? A: An open-frame supply is designed to be mounted inside a panel or chassis with exposed edges, not enclosed in a dedicated case.
- Q: How do I determine maximum load? A: Identify the total current draw of connected devices and select a supply with comfortable headroom above that total, considering peak loads.
- Q: Is a higher wattage supply always better? A: Not necessarily. Oversized supplies can increase cost and heat footprint; match supply to load plus modest headroom.
- Q: Are these power supplies compatible with all PoE devices? A: Not every supply is intended for lithium battery charging or high-current motor loads; verify device compatibility and polarity requirements.
