AC power supply PCR-LE2 series
Basic
This product has the following limit functions and protection functions.
• Limit Functions
Limits can be placed on the PCR-LE2 Series output voltage setting and frequency setting. They prevent damage to the load caused by mistaken operations and limit the current that flows through the load.
• Protection Functions
Protection functions apply limits when there is a danger of damaging the internal circuitry of the PCR-LE2 Series or to protect the DUT.
When a protection function is activated, an alarm (ALM-xx) or a trouble indication (TRBL-xx) is generated, and the output is turned off.

Output off |
Voltage upper limit Voltage lower limit |
Limit |
You will not be able to specify voltages that are outside of the set limit range. |
No |
Output overvoltage protection (OVP) |
Protection |
If the measured voltage exceeds the OVP value, an alarm occurs, and the output turns off. |
Yes |
Output undervoltage protection (UVP) |
Protection |
If the measured voltage falls below the UVP value, an alarm occurs, and the output turns off. |
Yes |
Frequency upper limit Frequency lower limit |
Limit |
You will not be able to specify frequencies that are outside of the set limit range. |
No |
Current limit |
Limit |
If the upper limit is exceeded, the output turns off, or the output voltage is controlled so that the limit value is not exceeded. You cannot set the lower limit. You can set how the PCR-LE2 Series behaves when the limit is exceeded (whether to turn off the output or control the output voltage). If you select to turn off the output, you can set the time that must elapse before the output is turned off when the current limit is exceeded. If you select to control the output voltage, the following functions will not be available. • Turn soft start on (set the rise time) • Execute power line abnormality simulations • Run sequences • Use the compensation function’s software sensing and regulation adjustment |
Selectable |
Peak current limit |
Limit |
This function instantly limits the peak output current. You can set positive and negative limits. |
No |
Internal semiconductor protection (OCP) |
Protection |
This function protects the internal semiconductors of the PCR-LE2 Series. If a temporary overcurrent—such as an inrush current—occurs, an alarm occurs, and the output turns off. |
Yes |
Input voltage drop protection |
Protection |
If the input voltage falls below the rating, a trouble indication occurs, and the output turns off. |
Yes |
Overload protection |
Protection |
If the output current exceeds the rated current or current limit, an alarm occurs, and the output turns off. |
Yes |
Overheat protection (OHP) |
Protection |
If the internal temperature increases abnormally, an alarm occurs, and the output turns off. |
