OUTPUT ADJUSTMENT RESISTOR VALUES

FOR

HR151-2805

Output Adjustment all HR151 models (single output):

The output can be adjusted upward by using the output adjust

(pin3). The resistance between output adjust (pin 3) and output

common (pin 4) will determine the magnitude of the increase

in the output. The table above is only applicable to

HR151-2805.
