Description
The PS‑2.5‑12‑333DTM1 is a 12 V DC external switching power supply adapter commonly used to power consumer and telecom broadband equipment such as set‑top boxes, modems, network devices, and similar devices that require a 12 V DC input. It appears in accessory and replacement PSU listings alongside compatible adapters and power bricks designed with multitarget compatibility.
Listings for this exact code show it alongside other identifiers such as G40DD‑120333‑A and are marketed as universal 12 V AC/DC adapters suitable for many CPE and telecom devices.
Key Features
-
Product Type: External switching power adapter (PSU)
-
Output Voltage: 12 V DC (common for broadband and network devices)
-
Likely Rated Current: Typically around 3.33 A (from the “333” in the model name indicating approx. 3.33 A) — which suggests around ~40 W output capacity (12 V × 3.33 A).
-
Input Voltage: 100–240 V AC, 50/60 Hz (worldwide mains support)
-
Protections: Over‑Voltage, Over‑Current, Short‑Circuit protection built into the adapter circuitry
-
Connector Type: Barrel‑style DC plug (often ~5.5×2.5 mm, but exact plug size varies by device configuration)
-
Application: Powering set‑top boxes, routers, modems, CPE telecom devices requiring a 12 V DC input and ~3 A supply
Technical Overview
-
Switching Technology: Uses a high‑efficiency switched‑mode power supply (SMPS) design to convert AC mains to regulated 12 V DC.
-
Typical Output Power: Approximately 40 W (based on 12 V × ~3.33 A rating inferred from model code).
-
Load Regulation: Maintains stable DC output under typical device load, with internal circuitry for voltage and current protection.
-
Compatibility: Often cross‑listed with universal adapters suitable for devices from Pace, Cisco/Xfinity, Comcast, and others (as shown in accessory listings).
