The **GP25B13A-R1B** is a high-efficiency AC/DC medical-grade power adapter manufactured by **Mean Well**. It belongs to the GP25 series, which is designed to meet stringent medical safety standards (2 x MOPP) and energy efficiency regulations. Below is a detailed breakdown of its electronic specifications and features. ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Mean Well | | **Output Type** | Triple Output (Dual/Triple DC Voltage) | | **Rated Power** | 25 Watts (approximately) | | **Input Voltage Range** | 90 ~ 264VAC (Universal Input) | | **Connector Type** | IEC320-C8 (2-pole AC inlet) | | **Safety Standard** | ANSI/AAMI ES60601-1 / EN60601-1 (Medical) | | **Efficiency Level** | Level VI (Energy Star / ErP Step 2) | --- ### 2. Detailed Output Configuration This specific model is a **triple output** adapter. It provides three different DC voltages simultaneously to power complex medical devices that require multiple logic levels. | Output Channel | Voltage | Rated Current | | :--- | :--- | :--- | | **Channel 1 (V1)** | +5V DC | 2.5A | | **Channel 2 (V2)** | +12V DC | 1.0A | | **Channel 3 (V3)** | -12V DC | 0.3A | --- ### 3. Core Electronic Features * **2 x MOPP Protection:** "Means of Patient Protection." This indicates double insulation between the primary (AC) and secondary (DC) circuits, ensuring the leakage current is extremely low ($<50\mu A$) to prevent electric shock in medical environments. * **Protection Circuits:** * **Short Circuit Protection:** Recovery after fault condition is removed. * **Overload Protection:** Typically 110% ~ 150% rated output power. * **Overvoltage Protection:** Shuts down the output to prevent damage to the connected device. * **Low No-load Power Consumption:** Consumes less than **0.3W** when the device is plugged in but not in use, meeting global green energy requirements. * **LED Indicator:** Features a built-in power-on LED for status monitoring. --- ### 4. Physical Characteristics * **Enclosure:** Fully enclosed plastic case (UL 94V-0 rated). * **Cable:** Usually equipped with a multi-pin DIN connector or specialized DC plug to handle the three separate voltage rails. * **Working Temperature:** -20°C to +70°C (with derating curves applied at high temperatures). --- ### 5. Common Applications Due to its triple output and medical certification, this part is commonly used in: 1. **Portable Medical Monitoring:** Patient monitors requiring 5V for logic and ±12V for analog sensors. 2. **Diagnostic Equipment:** Small ultrasonic or imaging devices. 3. **Laboratory Instruments:** Devices requiring precise dual-rail power for operational amplifiers. ---
