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 10µF 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. 11. “N N” for Negative remote ON/OFF. 12. “PP” for Positive remote ON/OFF. 178 July-2006 www.recom-international.com RP50-S Series INNOLINE DC/DC-Converter Specifications (refer to the standard application circuit, Ta: 25°C) Input Voltage Range Unde-Voltage Lockout Start-up Voltage Unde-Voltage Lockout Shuntdown Voltage Input Filter (Note 3) Input voltage variation 18 - 36, 36-75VDC 24V input 48V input 24V input 48V input dv/dt (24, 48V nom.) 17V typ. 34V typ. 15V typ. 32V typ.
