Remote ON/OFF
This converter has the ability to be remotely turned ON or OFF. The series may be ordered Active-High or Active-Low (place an option
‘R’ at the end of the part number). Active-High means that a logic high at the ENABLE pin will turn ON the supply (Figure 2). With
Active-High, if the ENABLE pin is left floating, the supply will be enabled. Active-Low means that a logic low at the ENABLE pin will
turn ON the supply (Figure 3). With Active-Low, if the ENABLE pin is left floating, the supply will be disabled. If remote On/Off is not
used on an Active-Low supply, short the Enable pin to –Vin.
Output Voltage Trim
The output is adjustable from +/–10% of the output voltage. To adjust the output voltage low, place a resistor between the TRIM and -
SENSE pins (Figure 4). To adjust the output voltage high, place a resistor between the +SENSE and TRIM pins (Figure 5). The value of
the TRIM resistor with respect to the desired output voltage can be found in Table 2 or derived from the following equations:
(888) 597-WALL

Note 2: While decreasing the output voltage, the maximum output current
remains the same, and while increasing the output voltage, the output
current is reduced to maintain the total output power at 50 W.
