The **HVS-16-R** is a high-performance, rack-mountable High Voltage (HV) Multiplexer/Switching system typically used in laboratory, industrial, and automated test equipment (ATE) environments. It is designed to route high-voltage signals from a single source to multiple output channels. --- ### Core Electronic Components The electronic architecture of the HVS-16-R is centered around isolation and signal integrity. Below are the primary electronic sections: | Component Type | Description | Function | | :--- | :--- | :--- | | **High-Voltage Relays** | Dry-circuit or Reed relays with high dielectric strength. | Performs the physical switching of HV signals. | | **Control Logic** | Microcontroller or FPGA-based logic board. | Processes commands (RS-232, USB, or Ethernet) to trigger relays. | | **Isolation Barrier** | Opto-isolators and galvanic isolation circuits. | Protects the low-voltage control electronics from high-voltage spikes. | | **LED Indicators** | Front-panel status diodes. | Visual feedback for active channels and power status. | | **Power Supply** | Internal AC/DC converter with filtering. | Provides stable DC voltage for the logic and relay coils. | --- ### Technical Specifications The HVS-16-R is defined by its ability to handle high potential (Hi-Pot) without arcing or leakage. * **Channel Count:** 16 independent channels. * **Voltage Rating:** Typically rated up to **5kV to 10kV DC/AC** (depending on specific sub-model configuration). * **Current Capacity:** Designed for low-current sensing/testing (typically < 1A). * **Switching Speed:** High-speed mechanical switching, usually in the range of 10ms to 50ms. * **Insulation Resistance:** $> 10^{12} \Omega$ to prevent cross-talk between channels. --- ### Functional Block Diagram (Simplified) ```mermaid graph LR Input[HV Source Input] --> Bus[Internal HV Bus] Bus --> R1[Relay 1] Bus --> R2[Relay 2] Bus --> R16[Relay 16] Logic[Control Interface] -- Isolated Signal --> R1 Logic -- Isolated Signal --> R2 Logic -- Isolated Signal --> R16 ``` ### Key Safety & Design Features 1. **Interlock System:** Most HVS-16-R units include a hardware safety interlock. If the circuit is broken, all relays default to the "Open" state to prevent accidental exposure. 2. **Creepage and Clearance:** The internal PCB layout utilizes wide spacing and specialized milling (slots) between traces to prevent surface tracking (arcing) at high voltages. 3. **Shielding:** The "R" in the model name usually denotes a Rack-mount chassis, which provides an Earth-grounded Faraday cage to minimize EMI/RFI interference.
