Overheat protective
function
• If an overcurrent keeps flowing due to overload, heat is generated
to activate the overheat protective function.
• Each protective function is designed to protect the internal
elements of the module, not the external equipment.
• The overload protective function is activated in 1 point increments
in terms of 1A to 3A/point.
• The overload protective function returns operation to normal when
the load becomes a rated load
• The overheat protective function is activated in 1 point increments.
• The overheat protective function automatically returns operation to
normal when heat reduces.
