DC_Power_Supply_ES-2303E – Datasheet
The ES2000 series are linear DC power supplies with 3 channels, 195W to 315W output. In constant voltage and
current operations, the power supply provides high regulation and low ripple & noise. Auto series and parallel
operations double output voltage and current. Heat sink and automatic cooling fan control give sufficient cooling to
the power supply and minimize fan noise. The output ON/OFF control and preset voltage & current function protect
the power supply and related loads from unexpected damages. The ES2000 series are widely used in applications
of powering operational amplifier, push pull stages, logic circuit and definition systems.
