The **2VS-10-R** is a specific model of a **Miniature High Voltage Power Supply**, typically manufactured by companies like *Ultravolt* (now part of Advanced Energy). These components are designed to convert a low-voltage DC input into a precisely regulated, high-voltage DC output. ### 1. Technical Specifications The model name "2VS-10-R" follows a specific nomenclature that describes its primary electrical characteristics: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Input Voltage** | 12V DC to 15V DC | Standard low-voltage logic supply. | | **Output Voltage** | 0 to 2,000V DC (2kV) | The "2" in the prefix indicates the kV rating. | | **Output Power** | 10 Watts | The "10" indicates the maximum wattage. | | **Polarity** | Reversible (R) | The "R" suffix indicates the polarity can be changed. | | **Regulation** | < 0.01% | High precision stability under load. | | **Ripple** | Low | Designed for sensitive electronic measurements. | --- ### 2. Key Internal Electronic Components A high-voltage module like the 2VS-10-R consists of several critical stages: * **PWM Controller:** Manages the switching frequency to regulate the output voltage. * **Step-up Transformer:** A specialized ferrite core transformer designed to handle high insulation requirements without arcing. * **Voltage Multiplier (Cockcroft-Walton Cascade):** A network of high-voltage capacitors and diodes that "pumps" the voltage up to the 2kV level. * **Feedback Network:** A high-precision resistive divider that sends a signal back to the controller to ensure the output remains steady regardless of load changes. --- ### 3. Pinout and Control Interface These modules are usually PCB-mounted and feature several interface pins: 1. **Input Power (+):** DC supply voltage. 2. **Input Ground:** Common return. 3. **Control Voltage:** Typically a 0-5V or 0-10V analog signal used to program the output voltage (e.g., 2.5V in = 1kV out). 4. **Voltage Monitor:** A low-voltage output (0-5V) that allows a microcontroller to read the actual output voltage for safety. 5. **Reference Voltage:** A stable onboard voltage source for use with external potentiometers. --- ### 4. Common Applications Due to its precision and compact size, the 2VS-10-R is used in: * **Photomultiplier Tubes (PMT):** Requiring stable, low-noise high voltage. * **Mass Spectrometry:** For ion acceleration. * **Electrostatic Chucks:** In semiconductor manufacturing. * **Scanning Electron Microscopes (SEM):** For electron beam control. ---
