Perf. Criteria A

1. Typical values at nominal input voltage and no load/full load.

2. Typical values at nominal input voltage and full load.

3. Typical values at nominal input voltage and full load in vertical orientation and with Eurocard-sized PCB ground planes to assist in heat dissipation.

For horizontal orientation, reduce the maximum temperatures by 10°C.

4. The ON/OFF control function can be positive or negative logic. The pin voltage is referenced to negative input.

Positive logic ON/OFF is standard, no suffix (Ex. RPP20-2405SW)

Negative logic ON/OFF option has suffix /N (Ex. RPP20-2405SW/N)

5. Requires an external 100µF/100V low ESR capacitor to meet EN61000-4-4 and EN61000-4-5

6. Case l: 50% Stress, Temperature at 50°C (Ground Benign).

7. 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.

Input Fuse is recommended, but optional. 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/100V MLCC

To ensure optimum thermal performance, use large areas of copper on the PCB to assist with heat dissipation and mount the converter vertically.
