DESCRIPTION

The PSAK75 series of AC/DC switching power supplies provides 75 Watts of continuous output power in an enclosed design. All models

have a single output and a universal input range. Some features include efficiency up to 89%, 0.98 typical power factor, active PFC, and

< 0.5W no load power consumption. These supplies are Energy Star compliant and have brown-out, over load, over voltage, over

temperature, and short circuit protection. All models are 100% full load burn-in tested.

SPECIFICATIONS: PSAK75 Series

All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.

We reserve the right to change specifications based on technological advances.
