Built-in FCC/EN55022 Class B Filter 4:1 Wide Input Voltage Range 40 Watts Output Power Ribbed or Baseplate Case Styles Min. Efficiency 86% 3kVDC Isolation Low Quiescent Current The RPP40-W series 4:1 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 RPP40-W is available in two case styles: the ribbed case for active cooling and the baseplate case for high vibration, bulkhead-mounting or for passive heatsink cooling applications. They are UL-60950-1 certified.

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. RPP40-2405SW Positive 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 baseplate is pressed firmly into place within the aluminium housing.The hydraulic press can leave tooling marks and deformations to both the housing and baseplate. 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 = 7.3°C/W (vertical) Tambient = Environment Temperature Rthcase-ambient = 11°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 RPP40-2405SW with 80% load. What is the maximum ambient operating temperature? Use converter vertical in application. Effmin = 87% @ Vnom Pout = 40W Poutapp = 40 x 0.80 = 32W Pdissipation = Ƞ Pout Ƞ - Pout = ~88% (from Eff vs Load Graph) Rth = 115°C - Tambient Tcasemax - Tambient --> 7.3°C/W = 4.36W Pdissipation Tambient = 83.15°C 32 - 32 = 4.36W Pdissipation = 0.88 www.recom-international.com REV: 0/2014 PP-33 RPP40-S_DW Series POWERLINE+ DC/DC-Converter Typical Characteristics -Vout External Output Trimming -Vout Trim Up Refer to Application Notes for suggested Resistor Values 10kW Trimpot Trim 10kW Trimpot Trim Trim Down 10kW Trimpot +Vout +Vout RPP40-2405SW / RPP40-2412SW Efficiency VS Load Vnom RPP40 -W Efficiency (%) 100 90 80 70 60 50 40 30 20 10 0 0 20 40 60 80 100 Output Load (%) Recommended PCB Layout Ribbed Case Single Output Dual Output C2 C1 Fuse PP-34 C1 C2 Top View C3 Fuse REV: 0/2014 Top View www.recom-power.com RPP40-S_DW 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.
