| Notes & safety | |
| Notes: | 1. Several options available for this series that change product model number. See Model Number Setup for more information. 2. Input source impedance: The power module will operate as specified without external components, assuming that the source voltage has a very low impedance and reasonable input voltage regulation. Highly inductive source impedances can affect the stability of the power module. Since real-world voltage source has finite impedance, performance can be improved by adding an external filter capacitor. -Recommended filter for 36Vin Nominal Input Models: Nippon Chemi-con KY series, 220µF/100V. -Recommended filter for 72Vin Nominal Input Models: Nippon Chemi-con KXJ series, 150µF/200V. 3. If remote sense is not being used, SENSE pins should be connected to corresponding polarity OUTPUT pins. 5. This product is Listed to applicable standards and requirements by UL. 6. BASE-PLATE GROUNDING: when two screw bolts are connected to shield plane, EMI could be reduced CAUTION: This power module is not internally fused. An input line fuse must always be used. *Due to advances in technology, specifications subject to change without notice. |
| Safety Approvals: | IEC/UL/EN60950-1, IEC/UL/EN62368-1, EN50155, EN45545-2 |
