Check out our PSUs 101 article to learn more about PSU protection features. Our protection features evaluation methodology is described in detail here.
|OCP||12V: 89A (125.71%), 12.095V 5V: 32.91A(131.64%), 4.97V 3.3V: 33.58A (134.32%), 3.27V 5VSB: 5.6A (186.7%), 85.56mV ripple|
|OTP||✓ (195°C @ main transformer)|
|SCP||12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓|
|SIP||Surge: MOV Inrush: NTC thermistor & bypass relay|
Over-current protection on the minor rails lands where we'd expect. However, the 5VSB rail should have a lower OCP threshold in order to avoid exceeding 50mV of ripple. The over-temperature protection limit is set quite high, which is often the case in CWT designs. Meanwhile, short circuit protection is accounted for on every rail. There is a MOV for surge protection, and the NTC thermistor (responsible for inrush current protection) is supported by a bypass relay now. That was missing from the previous-gen RMx PSUs.
