The EP-90 is rated at least 85% efficient at 100 VAC and 240 VAC input voltage and maximum
load.
A variety of industrial-grade safety circuitry will help protect your computer: OVP (Over Voltage
Protection), SCP (Short Circuit Protection), and OCP (Over Current Protection). Sometimes the
PSU will ālatchā into a protected shutdown state. This means that you will need to power off the
adapter and clear the fault before it will function again.
There are no user-replaceable fuses in the EP-90.
