Notes & safety
Notes: 1. It is necessary to equip the external input capacitors at the input of the module.
The capacitors should connect as close as possible to the input terminals ensuring module stability.
External Cin is Ruby-con BXF series, 100µF/250V.
2. If remote sense is not being used, SENSE pins should connect to corresponding polarity Vout pins.
3. Input Source Impedance: The power module will operate as specifications without external components, assuming that the source voltage has 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 external filter capacitor. Recommended external capacitor is TBD.
4. A. Iron base-plate dimension is 19” x 3.5” x 0.063” (height is EI standard 2U)
B. Heat sink is optional and P/N: 7G-0021A-F, 7G-0022A-F, 7G-0023A-F, 7G-0024A-F. Please refer to heat-sink selection guide.
5. Standard modules meet EMI Class A or Class B with external components. Contact factory for more information.
6. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. Recommended external capacitor is TBD.
7. BASE-PLATE GROUNDING: When four screw bolts to shield plane, the 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: IEC60950-1, UL60950-1, EN60950-1 (Pending)
RoHS Compliance: Yes
