The **Banner Engineering WLS28-2..145S** is a professional-grade LED strip light designed for industrial environments. The "145" in the model name indicates a housing length of **145 mm**, and the "S" suffix typically denotes the inclusion of an **ON/OFF toggle switch**. --- ### 1. Key Electronic Specifications The WLS28-2 series is engineered for efficiency and durability in harsh conditions. | Parameter | Specification | | :--- | :--- | | **Supply Voltage** | 12V DC to 30V DC | | **Current Consumption** | ~0.33A at 12V DC / ~0.13A at 30V DC | | **Luminous Color** | Typically Daylight White (other colors available) | | **Input Protection** | Reverse polarity and transient voltage protection | | **Switch Type** | Integrated Manual Toggle (ON/OFF) | --- ### 2. Internal Electronic Components The device is more than just a simple string of LEDs; it contains sophisticated circuitry to ensure longevity. * **LED Driver (Constant Current):** Unlike cheap LED strips that use resistors, the WLS28-2 uses a constant-current driver circuit. This ensures that the brightness remains consistent even if the input voltage fluctuates between 12V and 30V. * **High-Intensity LEDs:** Utilizes Surface Mount Device (SMD) LEDs mounted on a metal-core PCB for superior heat dissipation. * **Protection Circuitry:** * **Reverse Polarity Protection:** Prevents damage if the positive and negative wires are swapped during installation. * **Surge Suppression:** Protects the LEDs from voltage spikes common in industrial motor environments. * **Thermal Management:** The electronics are housed in an aluminum base which acts as a heat sink to prevent the LEDs from overheating, extending their lifespan to approximately 50,000 hours. --- ### 3. Wiring and Connectivity The electronics are interfaced through standard industrial connectors or cables. #### Pinout (for M12 Quick Disconnect models) | Pin | Wire Color | Function | | :--- | :--- | :--- | | 1 | Brown | +12V DC to 30V DC | | 3 | Blue | DC Common (Ground) | | 4 | Black | Not Used (Standard models) | --- ### 4. Environmental Ratings The electronic assembly is sealed to withstand industrial abuse. * **IP Rating:** IP50 (Standard models with switch). * **Duty Cycle:** Rated for 100% continuous operation. * **Operating Temp:** -40°C to +70°C (-40°F to +158°F). ---
