The **AC1060R-R24** is typically identified as a specialized **AC-DC Industrial Power Supply** or a power distribution module designed for 24V DC output. These components are frequently found in industrial automation, LED driver systems, or telecommunications hardware. ### 1. Technical Specifications Below is a summary of the typical electrical characteristics for this part: | Parameter | Specifications | | :--- | :--- | | **Input Voltage Range** | 85V AC – 264V AC (Universal Input) | | **Output Voltage** | 24V DC | | **Current Rating** | ~2.5A to 4.5A (Depending on thermal cooling) | | **Wattage** | 60 Watts to 100 Watts range | | **Efficiency** | >85% | | **Form Factor** | Open frame or Enclosed DIN-rail mount | --- ### 2. Key Electronic Internal Parts A module of this type consists of several critical sub-sections: #### A. Input Protection Section * **Fuse:** Protects the circuit from overcurrent. * **MOV (Metal Oxide Varistor):** Protects against high-voltage surges/spikes from the AC line. * **NTC Resistor:** Limits "inrush current" when the device is first powered on. #### B. Rectification & Filtering * **Bridge Rectifier:** Converts AC voltage into pulsating DC. * **Bulk Capacitor:** Large electrolytic capacitor used to smooth the pulsating DC into a stable high-voltage DC bus (approx. 310V-400V). #### C. Switching Section (SMPS) * **PWM Controller IC:** The "brain" that regulates the switching frequency to maintain a constant output. * **Power MOSFET:** Switches the high-voltage DC on and off at high frequencies (usually 50kHz - 100kHz) into the transformer. #### D. Isolation & Output * **High-Frequency Transformer:** Provides galvanic isolation between AC mains and the 24V output. * **Schottky Diodes:** Rectify the high-frequency AC from the transformer back into DC. * **LC Filter:** Inductors and capacitors used to remove high-frequency ripple/noise from the 24V rail. --- ### 3. Safety and Protection Features * **Overload Protection:** Shuts down the unit if the current draw exceeds the 24V rating. * **Short Circuit Protection (SCP):** Prevents fire or component failure if the output leads are crossed. * **Optocoupler Feedback:** Uses light to send voltage regulation signals back to the high-voltage side while maintaining electrical isolation.
