Besides covering all the input voltages from 24VDC up to 110VDC, the converters have a very wide operating temperature range of -45°C to +85°C without derating. Although the case size is very compact, the converter contains a built-in EMI filter, so no active external filter components are required. The RPR20 is available in three case styles: a low profile flat top case, a ribbed case with a built-in heatsink and the baseplate case for high vibration or bulkhead mounting applications. They are EN 50155 and EN 50121-3-2 compliant.

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. RPR20-2405S, RPR20-4805D-B. Add “1” before the suffix for negative logic: e.g. RPR20-2405S-1, RPR20-11005D-1B. Positive logic: 0= OFF, 1 = ON. The converter will be ON if the CTRL is left open. Negative logic: 1 = OFF, 0 = ON. The converter will be OFF if the CTRL is left open.. 2. 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. 3. The converter is supplied with a protective adhesive tape to keep the top surface clean. The tape is heat resistant and the converter can be soldered into place without removing the tape. The tape should be removed just before final installation.
