Wide-ranging specs DC output also supported

• -   Output voltage rating (AC): 1 to 300V
• -   Output frequency rating: 1 to 999.9Hz
• -   Output voltage rating (DC): ± 1.4 to ± 424V

In addition, the system supports a DC output mode and AC + DC output mode. The system can be useful in a wider range of fields such as chemistry- and physics-related areas.

Selectable response mode

Allows select of a response mode for the internal amplifier system depending on the load condition and application.

• -   Normal response (MEDIUM）: for testing various power supply environments
• -   Highly stable response (SLOW): for power supply for EMC testing sites

Power line abnormality simulation

In AC mode, it is possible to simulate power line abnormalities by setting the output of the PCR-LE2 series system to the state of a power outage, voltage drop (dip), or voltage increase (pop). This allows the ability to test switching power supplies and electronic equipment.

Various measuring functions

Output voltage/current RMS values, peak voltage / current, effective power/apparent power, and power factor can be measured. It is possible to analyze harmonics (up to 40th order) of the output current.

Sequence function

The output voltage, frequency, and waveform can be changed along the way, thus, power supply environment testing can be automated. In addition to AC output, DC output and AC + DC output in sequence are also available. With the resolution setting by increments of 0.1 ms, the system provides functions to set the starting phase, sudden phase shift, as well as a jump and pause function.

Sensing, Regulation adjustment

Even in cases in which load units are installed remotely, the voltage (RMS value) at the end of the load can be stabilized through correction of voltage drops. Hardware sensing and software sensing are provided as sensing function, allowing you to selectively use either one accordingly with the load condition and application.

Output current control

The current limiting function enables you to control the output current (RMS) at a certain level for continuous operation by a selectable time setting (time/continuous) for a trip operation. Continuity tests for electric facilities (distribution panels, circuit breakers, devices for wiring, etc.) can be performed under stable conditions.

Eco-friendly function (Power-conservation function)

• -   Sleep function
  The power unit goes into the sleep mode when no output is detected for a certain time to cut down on the power consumption.
• -   Energy-saving operation function
  You can utilize the energy-saving function to operate only the necessary power unit(s) depending on the required supply load.

External communication

RS232C (equipped as a standard). Remote control available with GPIB, USB, and LAN as options. Using LAN makes it possible to configure highly cost-effective systems, as LXI standard is supported.

Memory function

It is possible to store up to 99 data sets of the output frequency, voltage (AC/DC), and a cyclic waveform under the waveform bank number on the memory of the main unit.
In addition, you can use USB memory devices to store the data contained on the main unit memory, panel settings, power line abnormality simulations, and sequence data.

Standard supported

Usable for systems to test conformance to the IEC61000-3 and 4 Series standards. Optional applications software also offered. Please refer to the end of the brochure for details.

Front panel serving as a remote control

The front panel is detachable. With the optional extension cable, the panel functions as a remote control.

For "system interconnection tests" with reverse load flow

Conforming to the guideline for requirements of system interconnection technologies
*All the simulated reverse load flow power is consumed internally, thus, there will be no reverse load flow to the system.

Excellent maintenance ability due to the unit configuration

The PCR-LE2 series are a unit type configuration.The power unit can be serviced (replaced) by the unit of 1 kVA.
