1. Protects Circuit from excess current
The short circuit protection function
prevents the continued flow of short
current. After short current is detected,
load current is monitored, and if the load
returns to normal, the device returns to
normal operation.
2. No need for fuses, polyswitches, or
other protectors
The built-in short circuit protection
function eliminates the need for
overcurrent protectors, reducing
mounting costs and space requirements.
3. High capacity
Can control up to 0.5A (60V DC) load
current.

GU 1 Form A Short Circuit Protection (AQV112KL)
What is short circuit protection Non-latch type?
If the load current reaches a
predetermined overcurrent level, the
output-side short circuit protection
function cuts off the load current. It then
monitors the load current, and if it returns
to normal, automatically recovers to
normal device operation.
In order to operate the short circuit
protection function, ensure that the input
current is at least I
F
= 10 mA.
