DESCRIPTION
The PSAK650 series of AC/DC switching power supplies provides up to 652 Watts of continuous output power in an enclosed design. All models
have a single output and a universal input range with active PFC. Some features include efficiency up to 91%, 0.99 typical power factor, remote
on/off, and forced current sharing at parallel operation. These supplies have over load, over voltage, over temperature, and short circuit protection.
SPECIFICATIONS: PSAK650 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.
