Notes:
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
2. Measured with a 1uF M/C and a 10uF T/C.
3. An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A
ripple current for 48V/24V models. RECOM suggests: Nippon chemi-con KMF series, 220µF/100V, ESR 90mΩ.
4. The negative/ positive logic and pin length are optional ( see table ). The pin voltage is referenced to
negative input.
5. Heat sink is optional and P/N: 7G-0021, 7G-0022, 7G-0023, 7G-0024.
6. The RP50 meets level A and level B conducted emissions only with external components connected before
the input pin to the converter.
7. Maximum value at nominal input voltage and full load.
8. Typical value at nominal input voltage and full load.
9. BASEPLATE GROUNDING : Base-plate should be grounded at one of the four screw bolts prior to operation.
10. The converter is provided by basic insulation.
N” for Negative remote ON/OFF.
11. “N
12. “PP” for Positive remote ON/OFF.
