Input three-phase
imbalance positive offset
protection (line voltage)
Minimum: 15% (The input three-phase imbalance
positive offset recovery threshold is less than or
equal to 11%.)
Input three-phase
imbalance negative offset
protection (line voltage)
Maximum: –13% (The input three-phase
imbalance negative offset recovery threshold is
greater than or equal to –9%.)
Output overvoltage
protection threshold
● High-voltage mode: 1020–1050 V DC
● Low-voltage mode: 510–525 V DC
Output short circuit
protection
Able to tolerate a short circuit for an extended
period; current limiting is enabled in case of a
short circuit.
Lockout if three or more short circuits occur
within 1 minute
Overtemperature protection ● Normal mode: The module shuts down for
protection when the ambient temperature
exceeds 78±5°C and does not automatically
recover after the temperature becomes
normal.
● Silent mode: The module shuts down for
protection when the ambient temperature
exceeds 65±5°C and does not automatically
recover after the temperature becomes
normal.
Undertemperature
protection
When the ambient temperature is lower than –
40±5°C, the module shuts down for protection
and does not automatically recover.
