Coherent General 0513-156-00 REV.3 SCR Trigger & Voltage Equalizer Board

High-voltage control board used in laser power supplies and precision industrial electronics, the Coherent General 0513-156-00 REV.3 is a SCR Trigger & Voltage Equalizer Board designed to safely fire silicon-controlled rectifiers (SCRs) and balance voltage across series-connected SCR stacks. Technical Specifications: Manufacturer: Coherent General (a division of Coherent Inc.) Model Number: 0513-156-00 Revision: REV.3 Board Type: SCR Trigger & Voltage Equalizer Board Function: • Provides gate triggering signals to SCRs for controlled power switching • Equalizes voltage across series-connected SCRs to prevent overvoltage damage Trigger Type: Pulse triggering with opto-isolated or transformer-coupled firing circuit Voltage Equalization: Passive or active balancing using resistors, capacitors, or snubber networks Input Power: Typically low-voltage DC or AC (internally regulated for logic and drive circuits) Output: Gate pulses to SCR gate terminals; balancing network tied across anode-to-cathode Components: • Trigger transformers • Resistors/capacitors (equalization/snubbers) • Gate driver ICs or discrete transistors • Status or fault LEDs (optional) Mounting: Panel or chassis-mounted PCB Application: Laser excitation power supplies, HV DC rectifier bridges, industrial inverters Operating Temperature: 0 to 60 °C Conformal Coating: Likely included for HV insulation and environmental protection Safety: High-voltage handling precautions required for installation and servicing Please review pictures carefully and let us know if you have any questions!
