What are the threshold of under voltage (USF) and overvoltage (OSF) trip of Altivar 12.
The thresholds of USF and OSF detection for ATV12:
USF detection (Under voltage):
There are 2 thresholds for USF: one high and one low.
Low threshold (USFL): The product trips in USF fault when the voltage value is under USFL
(USFL = 184VDC)
High threshold (USFH): The fault disappears when the voltage reaches this value
(USFH = 233VDC)
OSF detection (Over voltage):
OSFL = 375VDC
OSFH = 380VDC
USF detection (Under voltage):
There are 2 thresholds for USF: one high and one low.
Low threshold (USFL): The product trips in USF fault when the voltage value is under USFL
(USFL = 184VDC)
High threshold (USFH): The fault disappears when the voltage reaches this value
(USFH = 233VDC)
OSF detection (Over voltage):
OSFL = 375VDC
OSFH = 380VDC
