Built-in FCC/EN55022 Class B Filter 2:1 Input Voltage Range Six Sided Shielded Enclosure Ribbed or Baseplate Case Styles Min. Efficiency 87% 2kVDC Isolation Low Quiescent Current DC/DC-Converter with 3 year Warranty 20 Watt 2:1 Single & Dual Output The RPP20 series 2:1 input range DC/DC converters are ideal for high end industrial applications and COTS Military applications where a very wide operating temperature range of -40°C to +115°C is required. Although the case size is very compact, the converter contains a built-in filter EN55022 Class B / FCC Level B without the need for any external components. The RPP20 is available in two case styles: the ribbed case for active cooling and the baseplate case for high vibration, bulkhead-mounting or for passive cooling applications. They are UL-60950-1 certified. Selection Guide 12V, 24V and 48V Input Types Input Range VDC Output Voltage VDC Output Current mA Efficiency(2) (Typ.)

Typical values at nominal input voltage and no load/full load. 2. Min. values at nominal input voltage and full load. 3. The ON/OFF pin voltage is referenced to negative input. The pin is pulled high internally. ON/OFF control is standard with positive logic: e.g. RPP20-2405S, RPP20-4805D-B. Pos. logic: 0= OFF, 1 = ON. The converter will be ON if the CTRL is left open. 4. Requires an external 100µF low ESR capacitor to meet EN61000-4-4 and EN61000-4-5 5. Case l: 50% Stress, Temperature at 50°C (Ground Benign). 6. To ensure a good all-round electrical contact, the bottom plate is pressed firmly into place into the aluminium case.The hydraulic press can leave tooling marks and deformations to both the case and plate. The case is anodised aluminium, so there will be natural variations in the case colour and the aluminium is not scratch resistant. Any resultant marks, scratches and colour varations are cosmetic only and do not affect the operation or performance of the converters. 7. Example: Tcase = Case Temperature Rthcase-ambient = 7.5°C/W (vertical) Tambient = Environment Temperature Rthcase-ambient = 11.5°C/W (horizontal) Pdissipation = Internal losses Tcase - Tambient Pin = Input Power Rthcase-ambient = Pdissipation Pout = Output Power Pout Ƞ = Efficiency under given Operating Conditions Pdissipation = Pin-Pout = Ƞ - Pout Rthcase-ambient = Thermal Impedance - Pout Practical Example: Take the RPP20-1205S with 50% load. What is the maximum ambient operating temperature? Use converter vertical in application. Effmin = 89% @ Vnom Pout = 20W Poutapp = 20 x 0.5 = 10W Pdissipation = Ƞ Pout Ƞ - Pout = ~88% (from Eff vs Load Graph) Rth = 115°C - Tambient Tcasemax - Tambient --> 7.5°C/W = 1.36W Pdissipation Tambient = 104.8°C 10 - 10 = 1.36W Pdissipation = 0.88 www.recom-international.com REV: 0/2014 PP-3 RPP20-S_D Series POWERLINE+ DC/DC-Converter Typical Characteristics RPP20-1209S Efficiency VS Output Load 100 Efficiency (%) 80 60 40 20 0 0 0.5 1 1.5 2 2.5 3 3.5 4 Output Load (%) Recommended PCB Layout Ribbed Case Single Output RPP20 C1 C2 Fuse Top View Dual Output C2 C1 C3 Fuse Top View PP-4 REV: 0/2014 www.recom-power.com RPP20-S_D Series POWERLINE+ DC/DC-Converter Recommended PCB Layout Baseplate Case- suggested PCB layout Dual Output Single Output C2 No tracks in this area (42 x 30mm) C1 C3 C3 Fuse Top View Input Fuse is recommended. Recommended fuse rating = double maximum input current, time delay type. Input Capacitor, C1, is required to meet EN61000 Surge and Fast Transient, otherwise it is not required for normal operation. Output Capacitors C2/C3 are recommended, but not required for normal operation. Typical capacitor values are 1µF MLCC To ensure optimum thermal performance, use large areas of copper on the PCB to assist with heat dissipation and mount the converter vertically.
