The **W2PV-C3SB2-R/UL** is a specialized power-related component, typically part of a specific industrial or commercial power management series (often associated with manufacturers like Omron or specific PDU/Relay board vendors). Below is a breakdown of the technical aspects and specifications common to this part category. --- ### 1. General Specifications This part is a **Power Relay / Switch Assembly** often used in power distribution units (PDUs) or industrial control panels. | Feature | Specification | | :--- | :--- | | **Component Type** | Relay / Power Switching Module | | **Mounting Style** | PCB or Panel Mount (Depending on base) | | **Safety Standard** | UL Recognized (UL File compliance) | | **Contact Material** | Silver Alloy (often AgNi or AgSnO2) | | **RoHS Status** | Compliant (indicated by -R suffix) | ### 2. Part Number Breakdown The nomenclature typically follows this logic: * **W2PV:** The series prefix, indicating a high-capacity power relay or terminal block interface. * **C3:** Refers to the contact configuration or the physical size/housing type. * **SB2:** Indicates the coil voltage or specific sensing behavior (e.g., Sensitive type, DC voltage rating). * **R:** Signifies RoHS (Restriction of Hazardous Substances) compliance. * **UL:** Signifies Underwriters Laboratories certification for safety in North American markets. ### 3. Key Electronic Functions #### A. Contact Configuration Usually, these parts feature a **SPST (Single Pole Single Throw)** or **DPST** configuration. They are designed to handle high inrush currents, making them suitable for: * Switching power supplies. * Motor starting. * Industrial lighting loads. #### B. Coil Sensitivity The "SB" designation often points to a "Sensitive" coil. This means the relay requires less power to energize the electromagnet compared to standard relays, which reduces heat dissipation on the control board. #### C. Insulation and Dielectric Strength Given its UL rating, the part is designed with high clearance and creepage distances to prevent electrical arcing between the low-voltage control side and the high-voltage load side. --- ### 4. Typical Applications 1. **Smart PDUs:** Used to toggle individual power outlets via software control. 2. **HVAC Controllers:** Managing compressors or fans. 3. **Industrial Automation:** Acting as an interface between a PLC (Programmable Logic Controller) and a heavy load. ---
