The FSP300-50UCB is a 300W 1U switching power supply engineered for space-constrained industrial chassis and rack-mounted systems. It is suitable for IPC controllers, 1U workstations, and storage platforms where compact size, thermal management, and stable output rails are critical.
This power supply offers a universal AC input range of 90–264 VAC at 47–63 Hz, simplifying global deployment. It meets the 80 PLUS Bronze efficiency standard, contributing to lower internal heat generation in airflow-limited designs. The unit provides standard output rails including +3.3 V, +5 V, +12 V, -12 V, and +5Vsb, with an optional -5 V rail.
Integrated protection functions include Over Current Protection (OCP), Over Voltage Protection (OVP), Over Temperature Protection (OTP), and short-circuit protection, ensuring reliable operation under industrial stress factors. The power supply has a specified MTBF of 100,000 hours at 25 °C.
With dimensions of 190 × 100 × 40.5 mm, the FSP300-50UCB is designed for 1U form factor applications. It holds safety approvals including CB 62368-1 and CB 60950-1.
