The **JWT100-5FF-R** is a specific model within the **JWT Series** of open-frame, triple-output AC-DC switching power supplies manufactured by **TDK-Lambda**. These units are widely recognized for their reliability in industrial and medical equipment. --- ### 1. General Specifications Below are the primary electrical characteristics of the JWT100-5FF-R: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | TDK-Lambda | | **Input Voltage Range** | 85 - 265 VAC (Universal Input) | | **Total Output Power** | 100 Watts | | **Number of Outputs** | 3 (Triple Output) | | **Cooling** | Convection Cooled | | **Safety Standard** | UL60950-1, CSA C22.2 No.60950-1, EN60950-1 | --- ### 2. Output Configuration This specific model (5FF) defines the voltage and current ratings for each of the three output channels: | Output | Nominal Voltage | Max Current | Adjustment Range | | :--- | :--- | :--- | :--- | | **V1** | +5 VDC | 13.0 A | 5.0 - 5.25 V | | **V2** | +15 VDC | 3.5 A | Fixed | | **V3** | -15 VDC | 1.0 A | Fixed | --- ### 3. Key Electronic Components & Features The "R" suffix and the series architecture include several critical electronic safeguards: * **PFC (Power Factor Correction):** The unit includes active power factor correction to ensure high efficiency and compliance with EN61000-3-2 standards. * **Remote ON/OFF Control:** The **"-R"** suffix specifically indicates that this model includes a **Remote On/Off** terminal, allowing the power supply to be toggled via an external signal without cutting the AC line. * **Overvoltage Protection (OVP):** Integrated on the +5V (V1) output to prevent damage to sensitive logic circuits. * **Overcurrent Protection (OCP):** Current limiting is standard on all outputs to prevent damage during short circuits or overloads. * **EMI Filtering:** Built-in line filters reduce conducted noise, meeting FCC Class B and VCCI-B standards. --- ### 4. Physical Layout The unit is an "Open Frame" type, meaning the PCB is exposed. - **Input Connector:** Usually located on one end (CN1). - **Output Connector:** High-current terminals or headers on the opposite end (CN2/CN3). - **Potentiometer:** A small trimmer (V.ADJ) is provided to fine-tune the 5V rail.
