50 PWR-01
Basic Features ｜ Protection functions and Alarms
Front-panel output terminal overcurrent protection (FOCP)
Front-panel output terminal overcurrent protection (FOCP) is activated when the output cur-
rent from the front-panel output terminal exceeds 10 A (typical value). The trip point is fixed.
If the FOCP trip point is lower than the OCP trip point, OCP is prioritized.
Overheat protection (OHP)
Overheat protection (OHP) is activated when the PWR-01’s internal temperature rises to an
abnormal level.
• When the PWR-01 is used in an environment that exceeds its operating ambient tem-
perature range (0 °C to +50 °C).
• When the PWR-01 is used with its air inlet or outlet port blocked.
• When the fan motor has stopped.
If you do not fix the problem that caused the OHP to be activated, OHP will be activated again
even if you turn the POWER switch off and on (p.61).
Incorrect sensing connection protection (SENSE)
Incorrect sensing connection protection is activated when the remote sensing cables are con-
nected with incorrect polarity (positive or negative), and the remote sensing function is then
used.
Low AC input protection (AC-FAIL)
Low AC input protection is activated when a low AC power line input voltage is detected.
You can set the PWR-01 so that when the problem that caused the AC-FAIL to be activated is
corrected, the output is automatically turned on (CF20:
AUTO).
Activation and release are repeated according to the variation in the AC power line.
