SUFFIX INFORMATION

none = Standard Ribbed Case

-B = Baseplate Case

For other CTRL logic (-1), case style (-F) or low temperature options (-L, -M, -T) please contact RECOM for availability.

The RPP20-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 compact, the converter

contains a built-in filter EN55022 Class B / FCC Level B without the need for any external

components. The RPP20-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 cooling appli-

cations. They are UL-60950-1 certified.

* ICE Technology

ICE (Innovation in Converter Excellence)

uses state-of-the-art techniques to

minimise internal power dissipation and

to increase the internal temperature

limits to extend the ambient operating

temperature range to the maximum.

1. 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. RPP20-2405SW, RPP20-4805DW-B.

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:

thcase-ambient = 7.5°C/W (vertical) Tcase = Case Temperature

thcase-ambient = 11.5°C/W (horizontal) Tambient = Environment Temperature

dissipation = Internal losses

thcase-ambient =

Tcase - Tambient

Pin = Input Power

Pout = Output Power

Practical Example:

Take the RPP20-2405SW with 60% load. What is the maximum ambient operating temperature? Use converter vertical in application.
