The **M2AS1-4334-R** is a specific part number belonging to the **M2AS series**, which are high-performance, modular **Power Entry Modules (PEMs)** manufactured by **InPower** (or similar electronic component vendors focusing on power distribution). These components are typically used in data centers, industrial power strips, and server rack environments. --- ### 1. Key Technical Specifications The part number follows a modular coding system. Below is a breakdown of the electronic and physical characteristics generally associated with this specific model: | Feature | Specification | | :--- | :--- | | **Component Type** | AC Power Entry Module / Modular Socket | | **Current Rating** | Typically 16A or 20A (depending on regional standards) | | **Voltage Rating** | 125V / 250V AC | | **Socket Type** | IEC C13 or C19 (Standardized for IT equipment) | | **Mounting Style** | Snap-in or Panel Mount | | **Termination** | Quick-connect terminals or Solder tabs | --- ### 2. Functional Components The "M2AS" series usually integrates several electronic functions into a single housing to save space: * **Integrated Circuit Breaker:** Protects the downstream device from overcurrent conditions. * **EMI/RFI Filtering:** Many variants include a built-in electromagnetic interference filter to ensure "clean" power delivery to sensitive electronics. * **Switching:** Often includes a rocker switch (illuminated or non-illuminated) for manual power control. * **Insulation:** High-grade thermoplastic housing rated for UL 94V-0 (flame retardancy). --- ### 3. Part Number Breakdown (Typical) While internal manufacturer codes vary, the suffix usually denotes: * **4334:** Refers to the specific configuration of the switch, the fuse holder type, and the mounting flange dimensions. * **-R:** Generally signifies **RoHS Compliance** (Restriction of Hazardous Substances), ensuring the part is lead-free. --- ### 4. Common Applications Due to its robust power handling, the M2AS1-4334-R is found in: 1. **Rack PDU (Power Distribution Units):** The "sockets" found on the back of server racks. 2. **Medical Equipment:** High-reliability power inlets. 3. **Industrial Machinery:** Providing a standardized interface for AC power input. 4. **Networking Hardware:** Switches, routers, and enterprise-grade firewalls. ---
