About the PCR-LE2 Documentation
Documentation Structure
The PCR-LE2 Series manual comprises the following documentation.
User’s Manual -Basic-
• Front panel and Rear panel
• Panel Operation Basics
• Selecting the Output Mode
• Setting the Output Voltage/ Frequency
• Turning Output On and Off
• Displaying Measurement Values
How to switch the display of measured value.
• Setting Limits
Limits can be placed on the PCR-LE2 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. You can set limits in advance according to the load condi-
tions.
• Using Protection Functions
The PCR-LE2 has the following protection functions.
Input voltage drop protection
Overheat protection (OHP)
Overload protection
Internal semiconductor protection (OCP)
Output undervoltage protection (UVP)
Output overvoltage protection (OVP)
• Using Memory
You can store data to the PCR-LE2’s internal memory and save
data to a USB memory device.

User's Manual -Advanced-
• Using the synchronization Function
The synchronization function synchronizes the frequency and
phase of the PCR-LE2 output voltage with a 50 Hz or 60 Hz input
power supply.
• Using the Voltage Compensation Function
The compensation function compensates for voltage drops in the
load cables when the load is connected to the PCR-LE2 over a
long distance.
• Using Power Line Abnormality Simulations
In AC mode, you can simulate power supply line errors by stop-
ping the PCR-LE2 output and decreasing and increasing the
voltage (to simulate voltage dips and pops).
• Using the Sequence Function
A sequence is a series of settings - values such as the output
voltage, frequency, and time - that are saved in advance and
are then recalled and automatically carried out in order at a later
time.
• Using the Harmonic Current Analysis Function
You can perform harmonic analysis of the output current.
• Generating Special Waveforms (Waveform bank)
You can generate peak-clipped sine waveforms.
• Setting the Output Impedance
The PCR-LE2 output impedance (output resistance) is approxi-
mately 0 Ω. Commercial power supplies have an impedance
(resistance) of several milliohms to several ohms. You can set
the PCR-LE2 output impedance. This enables you to simulate
the same environment as that which is provided by commercial
power supplies.
• Setting Soft Starts (The voltage rise time)
To prevent the output from being turned off (the alarm from be-
ing activated) and the voltage from dropping due to the load
device’s inrush current that exceeds the rated capacity of the
PCR-LE2, you can control the inrush current by having the output
voltage rise gradually when the output is turned on.
• Fixing the Internal Vcc
To minimize loss in the linear amplifier section, the PCR-LE2 au-
tomatically adjusts the linear amplifier supply voltage (Vcc) to a
level that is suitable for the output voltage. You can fix the Vcc
voltage of the PCR-LE2. This is useful when you want to prioritize
the output voltage response over the product’s efficiency.
• Selecting the Response
The PCR-LE2 uses a high-speed amplifier. Depending on the
load circuits (especially in the case of capacitive loads) and the
wiring conditions, the output may become unstable may oscil-
late. You can set the response speed of the internal amplifier
according to the load conditions and how you will use the PCR-
LE2.
• Using the Power Management Functions
The PCR-LE2 has the following two power management func-
tions: a sleep function and a power-saving function
• External analog signal control (optional)
You can use the optional analog signal interface board to control
the product with external analog signals.
