1. Maximum output deviation is 10% inclusive of remote sense. If remote sense is not being used,
the +Vsense should be connected to its corresponding +Vout and likewise the -Vsense should be connected
to its corresponding -Vout..
2. Measured with a 1uF M/C and a 10uF M/C(for dual outputs) or 1uF M/C and a 10uF T/C(for single outputs).
3.An external filter capacitor is required for normal operation.The capacitor should be capable of handing 1A ripple
current for 48V models. RECOM suggest: Nippon chemi-con KMF series, 220μF/100V, ESR 90m
.
4.The negative / positive logic and length are optional ( see table ).The pin voltage is referenced to negative input.
5. BELLCORE TR-NWT-000332. Case I: 50% Stress,Temperature at Tc=40°C.
(Ground fixed and controlled environment)
6. Heat sink is optional and P/N: 7G-0021, 7G-0022, 7G-0023, 7G-0024.
7.The RP75 meets level A and level B conducted emissions only with external components connected before
the input pin to the converter.
8. Maximum value at nominal input voltage and full load.
9. Single:Typical value at nominal input voltage and full load.
Dual:The efficiency test condition: Nominal input voltage and both outputs current are 7.5A.
10. BASEPLATE GROUNDING:Base-plate should be grounded at one of the four screw bolts prior to operation.
11.The converter is provided by basic insulation.
