Product Description

Kollmorgen manufactures the PSR3-23075-25-202. With a 250-Watt continuous dissipation rating, the Kollmorgen PSR3-23075-25-202 servo power supply is designed for high-performance thermal management. This is how well the device can convert electrical energy into thermal energy over time, so the internal temperature stays within bounds even under continuous load. In servo-controlled automation systems where continuous energy conversion puts a lot of thermal stress, this is crucial. To preserve the integrity of delicate electronics, system stability, reduce thermal fatigue, and increase the life of the power supply and the connected motion control components, you need to be able to dissipate heat without active cooling.

According to IEC 60529, the device’s IP20 ingress protection rating also shows its electromechanical safety and environmental adaptability. The marking "2" means the internal live components are protected against accidental human touch or large debris. This is important to keep the internal circuit integrity and worker safety. The power supply can only be used in dry controlled environments since the second number "0" means no protection against moisture or fluid entry. In industrial automation cells where liquid coolants or process vapors are strictly controlled, this is critical since it ensures the device runs in an environment where its enclosure ratings are not exceeded.

The PSR3-23075-25-202 is compatible with many industrial enclosures due to its 349 mm width and height configuration, which is 80 mm to 92 mm depending on the reference plane. Standardized PG16 connectors and this compact footprint allow safe and flexible integration into automation systems. The device is housed in a metal chassis that acts as an electromagnetic interference shield and mechanical barrier, which is important in high-density industrial environments where signal noise is common. Strategically placed holes in the housing improve passive airflow for natural convection cooling. By supporting the unit’s passive dissipation, this thermal management technique maximizes performance and ensures long-term reliability by allowing heat to escape without auxiliary cooling systems.
