Product Specifications

Product Description

A 3-phase power supply delivering a regulated 36V DC rail for motor drive and actuator applications, the SITOP PSU8200 6EP3446-8SB10-0AY0 provides 13A continuous at 94% efficiency for 36V motion control systems.

Optimized for 36V Motor Applications

36V DC is commonly used in stepper motor and low-voltage servo drive systems where higher voltage than 24V improves motor torque and speed characteristics. This PSU provides a clean, stabilized 36V rail adjustable from 36–42V, with 13A continuous output handling multiple small drives or a single larger motor axis.

Motor-Friendly Overload Behavior

Select constant-current mode for motor loads where inrush and intermittent peak torque demands briefly exceed rated current — the PSU delivers 19.5A (150%) for 5 seconds per minute while maintaining output voltage. The alternative latching shutdown mode suits non-motor loads where sustained overcurrent indicates a hard fault.

94% Efficiency Reduces Cabinet Heat

Only 30W of losses at full 468W load means less thermal stress on adjacent components and lower lifetime energy costs in continuously operating equipment. Parallel-ready design enables dual-unit 26A configurations for larger 36V installations.
