SAFETY AND PROTECTION

• Over-Voltage Protection (OVP)
Over-voltage protection for the 12V, 5V, and 3.3V DC outputs is required to comply with the ATX specification.
OVP shuts down the PSU in the event that the DC outputs exceed a set level, determined by the
PSU manufacturer.
• Over-Current Protection (OCP)
OCP is featured on the 3.3V, 5V, and 12V rails. OCP ensures that the output of the DC voltage rails remains
within safe operating limits.
• Over-Temperature Protection (OTP)
OTP ensures that the PSU will shut down when the internal temperature reaches a set point. This is usually as a
result of internal current overloading or a fan failure.
• Short-Circuit Protection (SCP)
A short-circuit is defined as any output impedance of less than 0.1 ohms. Amongst other things, SCP ensures
that the PSU shuts down should the 3.3V, 5V, and 12V rails short to any other rail, or to ground. It also ensures
that no damage should occur to the unit, or your PC's components in the event of a short.
• Over Power Protection (OPP)
Over power protection shuts off the PSU when the power drawn is between 115% and 135% of the rated power.
• Catastrophic Failure Protection
PSU must have protection circuitry to shut down safely to prevent damage from any catastrophic failures such
as flame, excessive smoke, charred PCB, fused PCB conductor, startling noise, emission of molten material, etc.
