7-3 Output Over Current Protection Function
Output voltage will be lowered when output current is in state of over current and start operating over current
protection circuit. (Over current protection set point : 105 to 250% of rating current value)
It will automatically recover when over current state is released. In order to avoid from damage, please do not hold
the over current state for more than 30sec.
If by any reason does not auto recover after releasing, please off the output at ON/OFF control or switch off to
reactivate.
7-4 Low Input Voltage Protection Function
This product builds in low input voltage protection function to avoid malfunction at low input voltage. Commencing
operation and termination voltage range is within the below table.
Model Commencing operation
Termination Voltage
BTA05 3.0 to 4.5V
BTA12 6.0 to 9.0V
BTA24 13 to 18V
BTA48 27 to 36V

7-5 Input Circuit Protection Function
Fuse is built in at input in order to protect circuit at secondary side when overcurrent flows to input by some
abnormalities.
Rating current and fusing current of the Built-in fuse is as below table. To assure fusing at abnormality, current
capacity of power supply should be more than fusing current which is stated in below table.
Model Rating Current Fusing Current
BTA05 1.25A Above 2.5A
BTA12 0.75A Above 1.5A
BTA24 0.75A Above 1.5A
BTA48 0.75A Above 1.5A
8. An example method to prevent inverse connection of input power supply.
This product will be damaged when input polarity is connected reversely. Please add protection circuit when
connection may be reversed.
Below diagram is an example of using fuse and diode.
