FAQs
Q1: What is the PW48V‑12V85W power supply used for?
A: The PW48V‑12V85W is a power adapter that converts standard mains AC input (100–240 V) into 12 V DC at up to 7.1 A, supplying a total output power of about 85 W — useful for powering RouterBOARD devices or networking gear requiring 12 V input.
Q2: What are the input and output specifications of this adapter?
A: Input: 100–240 V AC, 50/60 Hz. Output: 12 V DC, up to 7.1 A, 85 W max.
Q3: What devices is this power supply intended to power?
A: It is intended for MikroTik devices that require 12 V DC input and draw up to approximately 85 W — for example routers with high‑power wireless cards, small switches, or PoE‑out devices.
Q4: What are the advantages of using PW48V‑12V85W over lower‑power supplies?
A: Because of its higher current and wattage capacity, the PW48V‑12V85W can reliably power devices with higher power demands (e.g. multiple wireless cards, additional modules) and avoids voltage drop issues which might occur with undersized adapters on long cable runs.
Q5: What are the recommended use‑cases and conditions for PW48V‑12V85W?
A: Use it when powering devices with higher-than‑normal power draw, or when stacking multiple power‑hungry modules. It’s best used in a properly ventilated area to ensure heat dissipation, and in standard indoor electrical environments.
