VGS-150C-12 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI Inc recommends a PCB layout with a large copper area underneath the module to dissipate heat effectively. A minimum of 2 oz copper thickness is recommended, and the copper area should be connected to a heat sink or a metal plate for better heat dissipation.
• How do I ensure the module is properly soldered to the PCB?
  CUI Inc recommends using a soldering iron with a temperature range of 250°C to 260°C and a solder with a melting point of 217°C to 220°C. The module should be soldered within 3 seconds to 5 seconds per pin, and the solder joints should be inspected for any signs of cold soldering or bridging.
• What is the maximum allowable voltage deviation for the input voltage?
  The VGS-150C-12 can tolerate a maximum voltage deviation of ±10% of the nominal input voltage (150V) without affecting its performance or reliability.
• How do I protect the module from overvoltage and undervoltage conditions?
  CUI Inc recommends using overvoltage protection (OVP) and undervoltage protection (UVP) circuits to prevent damage to the module. The OVP circuit should be set to trigger at 165V, and the UVP circuit should be set to trigger at 135V.
• What is the recommended input capacitance value for the module?
  CUI Inc recommends using an input capacitance value of 10uF to 22uF, with a voltage rating of 200V or higher, to ensure stable operation and minimize input voltage ripple.
