The **ZWS150BP-48-R** is a high-reliability, industrial-grade AC-DC power supply manufactured by **TDK-Lambda**. It belongs to the ZWS-BP series, which is specifically designed for high peak load applications. --- ### ## Technical Specifications Overview Below are the primary electrical characteristics of the ZWS150BP-48-R: | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 85 - 265 VAC (47-63Hz) or 120 - 370 VDC | | **Output Voltage** | 48 VDC | | **Output Power (Rated)** | 151.2 Watts | | **Peak Power Capability** | Up to 200% of rated load (brief durations) | | **Efficiency** | ~89% (at 200VAC input) | | **Cooling** | Convection Cooled (no fans required) | | **Mounting Type** | Open Frame / Chassis Mount | --- ### ## Key Electronic Components & Features ### 1. The "-R" Suffix: Remote ON/OFF The "R" designation in the part number indicates the **Remote ON/OFF control** feature. This allows an external signal to toggle the power supply without disconnecting the AC mains, which is essential for automated systems and energy-saving standby modes. ### 2. Power Factor Correction (PFC) This unit features **Active PFC**, ensuring compliance with EN61000-3-2 harmonics standards. This reduces electrical noise and improves the efficiency of the power grid utilization. ### 3. Peak Load Handling Unlike standard power supplies, the ZWS-BP series is engineered with robust capacitors and magnetic components (transformers/inductors) that can handle **peak currents** significantly higher than the continuous rating. This is ideal for: * Starting motors. * Actuating solenoids. * Powering printers or scanners during high-activity cycles. ### 4. Protection Circuitry The internal PCB includes several safety sub-systems: * **Overcurrent Protection (OCP):** Shuts down or limits current if a short circuit occurs. * **Overvoltage Protection (OVP):** Protects sensitive 48V electronics from spikes. * **Thermal Protection:** Reduces output if the internal temperature exceeds safe operating limits. --- ### ## Physical Connections The board typically uses industrial-standard connectors: * **Input (CN1):** JST or similar header for Line, Neutral, and Ground. * **Output (CN51):** DC output terminals. * **Remote Signal (CN52):** Small 2-pin header for the remote ON/OFF trigger. ---
