| Overvoltage detection | Turns off the load when a voltage that is 110 % of the rating or higher is applied. |
|---|
| Reverse-connection detection | Turns off the load when approximately -1 % of the rated current flows through the DC INPUT terminals. |
|---|
| Overheat detection, overcurrent detection of the front-panel DC INPUT terminals | Turns off the load when the heatsink temperature reaches 100 °C. Or, turns off the load when a current of 30 A or higher is flowing through the front-panel DC INPUT terminals. |
|---|
| Alarm input detection | Turns off the load when a voltage between 0 V and 1.5 V is applied to ALARM INPUT (pin 6) of the EXT CONT connector. |
|---|
| Parallel operation anomaly detection | Turns off the load when any of the following errors occurs.
• An error occurs in the communication between the master unit and slave unit during parallel operation.
• slave unit’s power supply is interrupted. slave unit’s power supply is interrupted.
• An overheating was detected on the master or slave unit.
• An overcurrent flows through the front-panel DC INPUT terminals.
