Generally, no. Benchtop power supplies should be operated in their intended orientation, typically resting on their rubber feet. Placing the unit on its side may block the air intake or exhaust vents, disrupting the cooling airflow. This can lead to internal overheating, performance instability, or permanent damage to the unit.
However, some models designed with specific forced-air cooling systems (such as front-to-rear airflow) may support flexible installation orientations. Please strictly refer to the product user manual or datasheet to verify the allowable installation methods for your specific model.
