UL-60950-1 Certified
E224736
The RPP50 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 -45°C to +120°C is required.
Although the case size is very compact, the converter contains a built-in filter EN55022 Class B / FCC Level B wit-
hout the need for any external components. The RPP50 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.
* 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.

Notes :
1. Typical values at nominal input voltage and no load/full load.
2. Typical 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.RPP50-4805S.
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.
