The **M2PHS2H-15A-R/Q** is a specific technical part number, typically associated with high-current **Power Distribution Units (PDUs)** or **Power Strips** used in industrial and server rack environments (often manufactured by brands like Legrand, Raritan, or specialized power component suppliers). Below is a breakdown of the electronic components and specifications typical for this part series. ### 1. General Specifications The "15A" in the part number signifies its current rating, and the "R/Q" suffix usually refers to specific mounting or outlet configurations. | Feature | Specification | | :--- | :--- | | **Max Current** | 15 Amperes | | **Nominal Voltage** | 120V - 125V AC | | **Frequency** | 50/60 Hz | | **Mounting Type** | Rackmount (Horizontal or Vertical) | | **Plug Type** | NEMA 5-15P (Standard 3-prong) | --- ### 2. Key Electronic Components A PDU of this type contains several critical electronic sub-assemblies to ensure safety and power stability: #### A. Overcurrent Protection (Circuit Breaker) * **Component:** Thermal-Magnetic Circuit Breaker. * **Function:** Protects the connected equipment and the unit itself from drawing more than 15 Amps. If a short circuit occurs, the breaker trips to prevent fire or wire melting. #### B. Surge Suppression (MOV) * **Component:** Metal Oxide Varistors (MOVs). * **Function:** These components act as "pressure valves" for electricity. If a voltage spike occurs (e.g., from lightning or grid switching), the MOVs shunt the excess energy to the ground, protecting sensitive server electronics. #### C. Power Indicators * **Component:** Neon lamps or LEDs with current-limiting resistors. * **Function:** Visual confirmation that the unit is receiving power and that the grounding is functional. #### D. Internal Wiring and Bus Bars * **Material:** High-grade copper or brass. * **Design:** Heavy-duty gauge (typically 14 AWG for 15A) to minimize heat buildup and voltage drop over the length of the unit. --- ### 3. Mechanical & Interface Features * **Outlets:** Typically NEMA 5-15R receptacles. * **Chassis:** Cold-rolled steel or aluminum for heat dissipation and EMI (Electromagnetic Interference) shielding. * **R/Q Suffix:** This often denotes **Quick-Connect** terminals or a **Resettable** breaker configuration, depending on the specific manufacturer's catalog. --- ### 4. Safety Standards Electronic parts in this category must strictly adhere to international safety certifications: 1. **UL 60950-1:** Safety for Information Technology Equipment. 2. **RoHS Compliant:** Ensuring the electronics do not contain lead, mercury, or other hazardous substances. ---
