Note
1.
Maximum output deviation is 10% inclusive of trim. If remote sense is not being used, the +V sense should be connected to its corresponding
+OUTPUT and likewise the –sense should be connected to its corresponding –OUTPUT.
2.
An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V models. Power mate
suggest: Nippon chemi-con KMF series, 220 F/100V, ESR 90m .
3.
The negative / positive logic and pin length are optional ( see table ). The pin voltage is referenced to negative input.
4.
Heat sink is optional and P/N
7G-00297G-00307G-00317G-0032.
5.
The QEB125 meets level A and level B conducted emissions only with external components connected before the input pin to the converter.
6.
Typical value at nominal input voltage and full load
7.
BASEPLATE GROUNGING
Base-plate should be grounded at one of the four screw bolts prior to operation.
8.
The converter is provided by basic insulation.
