The **Tripp Lite PDUMH15NET2LX** is a 1.44kW Single-Phase Switched PDU (Power Distribution Unit) designed for network-grade power management. Below is an explanation of its key electronic components and technical specifications. --- ## 1. Core Technical Specifications The electrical foundation of the unit determines its capacity and compatibility with server room environments. | Feature | Specification | |:---|:---| | **Voltage Compatibility** | 100V, 120V AC | | **Amperage** | 15A (Agency de-rated to 12A continuous) | | **Frequency** | 50/60 Hz | | **Plug Type** | NEMA 5-15P | | **Outlets** | 8 x NEMA 5-15R | | **Form Factor** | 1U Rackmount | --- ## 2. Key Electronic Components ### A. LX Platform Network Interface The "LX" in the model name refers to the built-in **HTML5-based network interface**. * **Microcontroller:** Runs a Linux-based OS for secure remote access. * **Java-Free Interface:** Unlike older models, this uses modern web standards, eliminating the need for Java plug-ins. * **SNMP Support:** Allows integration with Network Management Systems (NMS) for automated monitoring. ### B. Individual Outlet Switching Each of the 8 NEMA 5-15R outlets is equipped with an internal **electromagnetic relay**. * **Function:** Allows users to turn individual outlets on or off remotely. * **Use Case:** Rebooting locked-up servers or power-cycling equipment without physical access to the data center. ### C. Digital Load Meter The front panel features a 2-digit LED display connected to internal **current sensors**. * **Real-time Monitoring:** Displays the total amperage being drawn by all connected equipment. * **Threshold Alerts:** The electronics can trigger SNMP traps or email alerts if the current exceeds a pre-set threshold, preventing circuit breaker trips. ### D. Environmental Sensor Port The unit includes an **RJ45 communication port** designed for the EnviroSense2 (E2) series of probes. * **Functionality:** Allows the PDU to monitor ambient temperature, humidity, and dry-contact closures (like door sensors). --- ## 3. Circuit Protection & Safety * **Circuit Breaker:** A physical 15A breaker protects the internal circuitry and connected loads from overcurrent conditions. * **EMI/RFI Filtering:** Internal capacitors and inductors filter out electromagnetic and radio frequency interference that could disrupt sensitive server electronics. * **Grounding Lug:** A dedicated chassis screw for supplemental grounding to the server rack. --- ## 4. Operational Logic 1. **Input:** AC power enters via the NEMA 5-15P cord. 2. **Processing:** The LX Platform logic board monitors the current flow and network commands. 3. **Output:** Power is distributed to the 8 outlets; the state of each (Open/Closed) is dictated by the onboard relays. 4. **Feedback:** Status data is sent via the Ethernet port to the administrator.
