•
Be sure to operate the unit within its maximum load current. If the
maximum load current exceeds this range, a malfunction or PL damage may occur.
• Design your electrical system by adding the load current and voltage
values to the terminal voltage. If load current value used is large, a
maximum voltage of 1.5V will exist between the terminals.
• When connecting an induction load, be sure to connect the above
drawing's protection diode(*1).
