The **GS160A15-R7B** is a high-reliability, industrial-grade AC-to-DC desktop power supply manufactured by **MEAN WELL**. It is part of the GS160 series, known for its energy efficiency and robust protection features. ### 1. Technical Specifications The part number itself defines the primary electrical characteristics of the unit: | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 90 ~ 264VAC (Universal Input) | | **Output Voltage** | 15V DC | | **Rated Current** | 9.6A | | **Rated Power** | 144W | | **Efficiency** | ~92.5% (Level VI compliant) | | **DC Connector Type** | Power DIN 4-Pin (R7B) | | **Operating Temperature** | -30°C to +70°C | --- ### 2. Key Internal Electronic Components & Features The GS160A15-R7B utilizes a sophisticated internal circuit design to ensure stability and safety: * **PFC Circuitry:** Includes active **Power Factor Correction (PFC)**, ensuring a PF > 0.94. This reduces harmonic distortion on the AC line. * **Protection Circuits:** * **Short Circuit Protection:** Auto-recovery once the fault is removed. * **Overload Protection:** Limits output current to 105% ~ 150% of rated power. * **Overvoltage Protection:** Clamps output to prevent damage to the connected load (typically 110%~140% of rated voltage). * **Overtemperature Protection:** Shuts down the unit if internal thermistors detect excessive heat. * **EMI Filtering:** Built-in EMI filter meeting EN55032 Class B standards, minimizing electromagnetic interference with other electronic devices. * **LED Indicator:** A simple green LED on the chassis indicates the "Power On" status. --- ### 3. Connector Pinout (R7B Type) The "R7B" suffix refers to the specific 4-pin Power DIN connector. Understanding the pinout is critical for electronic integration: | Pin Number | Assignment | | :--- | :--- | | **Pin 1** | +V (Positive) | | **Pin 2** | +V (Positive) | | **Pin 3** | -V (Negative/Ground) | | **Pin 4** | -V (Negative/Ground) | | **Shell** | FG (Frame Ground) | --- ### 4. Typical Applications Due to its high wattage and stable 15V output, this part is commonly used for: * Commercial telecommunications equipment. * Industrial automation controllers. * High-end POS (Point of Sale) systems. * Medical devices (where non-patient contact is required).
