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. Positive logic: 0= OFF, 1 = ON. The converter will be ON 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. 4. The RPR series are optionally available with a ribbed heatsink case style. They will then meet Tx requirements without an external heatsink. Please contact you RECOM supplier for more information.

Recommended fuse rating = double maximum input current, time delay type. To ensure optimum thermal performance, use large areas of copper on the PCB to assist with heat dissipation and mount the converter vertically.
