APPLICATION NOTES
OUTPUT VOLTAGE ADJUSTMENT
FUSING
The WPN20R Series of converters are not internally fused. In order to maintain maximum safety an input line fuse should always be included. A slow blow, UL listed, 8A fuse
is recommended for all models.
Remote on/off
The WPN20R Series of converters are equipped with a primary on/off control pin for increased system fl exibility. The input is TTL open-collector and/or CMOS open-drain
compatible. The primary on/off pin uses positive logic, which turns the unit off when a logic low signal is applied (<0.7V). The fi gure below illustrates the typical external
connections to enable this function. If no connection is made to the primary on/off control pin, the module will operate normally.
When the output voltage is trimmed up, output current must be derated so that the maximum output power (shown in the selection table) is not
exceeded.
