Mean Well SD-15 Series Installation Manual

Installation Manual
 Type： DC-DC converter（Families：PSD, SD, RSD）
 Introduction
A DC-DC converter is a device used to convert a DC source from one voltage level to another. Mean Well's DC-DC
converters equipped with internal EMI filter stage that possess the required EMC performance.
 Installation
（1） Before commencing any installation or maintenance work, please disconnect your system from the
utility. Ensure that it cannot be re-connected inadvertently!
For PCB type, at least 5mm insulation distance around the unit should be kept.
（2）
（3） Allow good ventilation for the unit in use to prevent it from overheating. Also, a 10-15 cm clearance
must be kept when the adjacent device is a heat source.
（4） Mounting orientations other than standard orientation or operate under high ambient temperature
may increase the internal component temperature and will require a de-rating in output current.
Please refer to the specification sheets to receive the optimum mounting position and information
about the de-rating curve.
