NOTES

(1) Typical Value at Nominal Input Voltage and Full Load

(2) Typical Value at Nominal Input Voltage and No Load

(3) Maximum Value at Nominal Input Voltage and Full Load

(4) Test by Minimum Input and Constant Resistive Load

(5) 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 +OUTPUT pin or the –OUTPUT pin.

(6) The CTRL pin voltage is referenced to –INPUT. (See “Product Options” table for suffix options)

(7) The JFW Series meets EN55022 Class A and Class B only with external components connected to the input pins of the converter.

(8) An external filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5.

The filter capacitor suggested is Nippon chemi-con KY series, 220µF/100V, ESR 48mΩ.

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.
