CPCI DC/DC Part. Nr.: D575.00251 Output Voltage / Current Ratings Chart Symbol: "★" OVP built-in. "@" Adjustable. "#" Remote sensing. "≡" 3rd-wire Load Sharing. "⊙" Installed with Or-ing diode. "▲" Magnetic Amplifier. "●" Installed with Post-regulator. ““ Common Choke. “=“ Droop Current Charing Remark: Peak load less than 60sec. with duty cycle <10%. Max. load is the continuous operating load of each rail. But the max. load of each rail can't be drawn from all outputs at the same time. Total max. power of VO1 and VO2 should be less than 300W Mechanical dimensions: mm (inches) Input &...
