FAQ

  • Q: Can I connect multiple FC-PSU-UNI4825U units in parallel?
    A: Yes. Built-in output diode supports parallel operation for higher current or redundancy. This enables system expansion without additional components.
  • Q: What causes the under-voltage alarm to trigger?
    A: Alarm relay de-energizes when output drops below 44V DC. This provides early warning of input power issues or overload conditions.
  • Q: What is the derating requirement above 50°C?
    A: Output current reduces by 30W per °C above 50°C. At 60°C, maximum output is approximately 900W (18.75A). Plan installations accordingly for hot environments.
