Features

* Work stably within a wide power suppy voltage range(vcc=25 to 60V).
* Contain a relay driver(Max I 6=80mA)
* Work as either latching function or automatic resetting function by using pin 3. (in both overload detection and output offset detection, either function can be selected.)
* Need only single power supply
* Both positive and negative output offset can be detected through the same pin.(output offset detection through pin 2)
* AC voltage can be detected.(for AC-power OFF mute through pin 4)
* The time delay from amplifier power ON to relay ON can be freely set by selecting external compo.
