Product Description:

The 502-03817-03 is a power interface module built by Kollmorgen for the PIC900 Drives series. Designed for panel-mounted automation cabinets, it distributes low-voltage supplies to control electronics and sensor loads inside an integrated motion platform. The module converts line energy from its host stack into stabilized ±15 V and +5 V rails, letting associated feedback cards and logic circuits draw current without additional supplies. It therefore acts as an auxiliary power resource that keeps peripheral boards operating within defined thresholds during machine cycles.

The enclosure measures 12 in in height, 2.4 in in width, and 8.4 in in depth, so it occupies a narrow vertical slot beside the main power stages yet still leaves clearance for airflow. At the input the card draws 2 A, a value engineers use for fuse sizing and cable gauge selection. Internally it can deliver a combined 60 W of total power among three regulated outputs: up to 1.5 A on the +15 V rail, 1.5 A on the –15 V rail, and 8.5 A on the +5 V rail. These currents are intended for encoders, analog amplifiers, and digital logic that share a common reference with the drive bus. The modest current draw and small footprint allow dense stacking of multiple cards without exceeding cabinet thermal budgets.

Environmental limits align with standard industrial enclosures. Continuous service is permitted from 7 °C to 55 °C, while non-operating storage may range between −40 °C and 85 °C without component damage. Shock events up to 15 g for 11 msec and vibration loads of 2 g at 0.15 mm amplitude do not impair functionality, making the module suitable for machinery exposed to fast pneumatic tooling or mobile platforms. These mechanical tolerances complement the electrical ratings outlined above and ensure stable auxiliary power even when installation conditions are demanding.
