XVIII. Description of driver’s protection functions: controller provides overvoltage,
under-voltage, overheat and over-current protection
1.
Over voltage, under-voltage protection:
when external power supply is higher or lower than
pre-set voltage value threshold, output of controller will be cut off. The range of normal
working voltage is 10-50v. Meanwhile, under-voltage & over voltage value can be set
according to customer’s requirements.
2.
Overheat protection:
Controller contains an internal temperature detection circuit, when
detected temperature exceeds 80
℃
, output stage of controller will be fully off.
3.
Over-current protection:
controller contains an internal current detection circuit, when
detected output current of controller reaches to over-current protection threshold, controller will
enter into over-current protection state.
Note: supposing that driver is under forward start status, when detected working current exceeds the
current threshold, driver will immediately cut off the power stage and stop output. After
troubleshooting, disconnect forward start, connect them again to remove protection.
