The **LHZ-115-R** is a specific type of **high-voltage power supply module** (often classified as a DC-DC converter or high-voltage generator) commonly used in industrial applications such as air purification, static elimination, or ozone generation. Below is a breakdown of its electronic characteristics and components. --- ### 1. Technical Specifications The "115" in the model name typically refers to the input voltage (115V AC), while the "R" often signifies a specific output polarity or mounting configuration. | Feature | Specification (Typical) | | :--- | :--- | | **Input Voltage** | 115V AC (Standard US Mains) | | **Output Voltage** | ~10kV to 15kV DC (High Voltage) | | **Output Current** | Very Low (Microampere range) | | **Frequency** | 50/60 Hz | | **Circuit Type** | Solid State / Encapsulated | --- ### 2. Internal Electronic Components To generate high voltage from a standard AC input, these modules generally contain the following electronic stages: * **Step-up Transformer:** A ferrite-core transformer that boosts the 115V AC to a higher intermediate AC voltage. * **Voltage Multiplier (Cockcroft-Walton Cascade):** A network of high-voltage **Diodes** and **Capacitors** that rectifies the AC and "pumps" the voltage up to the final DC kilovolt (kV) level. * **Encapsulation (Potting Compound):** The internal parts are usually encased in epoxy resin to prevent electrical arcing (corona discharge) and to protect against moisture. * **Bleeder Resistor:** A high-resistance safety component that slowly discharges the internal capacitors when power is disconnected. --- ### 3. Pinout and Connectivity These units typically feature simple wiring to ensure safety and ease of integration: 1. **Input Leads (Low Voltage):** Usually two wires (Black/White) meant for the 115V AC supply. 2. **Output Lead (High Voltage):** A thick, heavily insulated wire (often Red or White) that carries the high-voltage DC. 3. **Ground/Reference:** A wire or mounting tab that must be connected to the system ground to complete the circuit. --- ### 4. Safety Considerations Working with the LHZ-115-R requires caution due to the high output voltage: * **Discharge Time:** Even after turning off the power, the unit may hold a capacitive charge. * **Insulation:** Ensure the high-voltage lead is kept away from low-voltage components to avoid "crosstalk" or damage. * **Mounting:** Use non-conductive standoffs if the chassis is not specifically designed for high-voltage isolation.
