NOTES

1.Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an

external resistor between the TRIM pin and either the +Vout pin or the –Vout pin.

2.The JFC30 series can only meet EMI Class A or Class B with external components added. See page 5 for more details.

3.An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5.

- For 12VDC nominal input models we recommend connecting an aluminum electrolytic capacitor (Nippon chemi-con KY series,

220µF/100V)

and a TVS (SMDJ58A, 58V, 3000 Watt peak pulse power) diode in parallel.

- For 24VDC and 48VDC nominal input models we recommend an aluminum electrolytic capacitor (Nippon chemi-con KY series,

220µF/100V).

4.Both positive logic and negative logic remote ON/OFF control is available. Positive logic remote ON/OFF comes standard; for negative

logic

remote ON/OFF add the suffix “R” to the model number (Ex: JFC24S05-30R).

5.There are several different options available for this series. Please see the “Model Number Setup” on page 5 for all options and ordering

information.

6.Optional heatsink is available. Please call factory for more information.

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.
