Detect threshold level is fixed.
11-2-12. Abnormal Temperature of Converter
When converter internal measured temperature exceeds detect threshold level (about more than 80 degree C)
Abnormal Temperature of Converter Alarm is triggered. Detect threshold level is fixed.
11-2-13. Hardware Over Voltage
When over voltage circuit comparator detects voltage over the threshold level, the Hardware Over Voltage Alarm is
triggered. Detect threshold level is fixed.
11-2-14. System Alert
When Abnormality is detected in this converter, System Alarm will be triggered.
Alarm due to System Alert is not covered by Alarm Recovery procedures.

Explanation of Functions and Precautions
12-1. Input Voltage Range
Input voltage range is 150 – 300VDC for LVDC, and 240 – 400VDC for HVDC.
Input voltage which is out of specification might cause unit damage.
12-2. Output Voltage Range
Output voltage setting range is 150 – 300VDC for HVDC and 240 – 400VDC forLVDC.
Set output voltage is via RS-485 communication.
12-3. Constant Current Range
Constant current setting range is 0 – 52A for HVDC and 0 – 42A for LVDC.
Set constant current is via RS-485 communication.
12-4. Input Output Range
Please use this product within a predetermined Input Output Range.
