High-performance multifunctional AC Power SuppliesPCR-LE/LE2 Series

New stage of AC power supply supporting new energy field

The PCR-LE Series is a new line of advanced multifunctional AC power supplies that have been developed from the former PCR-L/LA Series (linear amplifier type). The PCR-LE Series provides high reliability and support to various applications by taking advantage of features that can freely control broadband waveform. Moreover, the PCR-LE Series can be configured as a core device of a test system combined with Electronic Loads and Power Analyzers for “Grid Connection Testing” in regard to dispersed power generation, such as Solar Power, Wind Power, Fuel Cell, and Gas Engine referred to as “New Energy Field”. With various options, the low frequency immunity test and various power environment tests are supported. The options for parallel operation and three-phase operation enable you to expand a single-phase system up to 27 kVA, single-phase three wires system up to 54 kVA, and a three-phase system up to 81 kVA. The system can be applied to a large-scale EMC site for testing of industrial high-capacity air conditioners.


Extended system for large capacity applications. Flexible configuration in models.

It is possible to expand to 27 kVA (single phase), 54 kVA (single phase 3-wire), and 81 kVA (three phase) by using the parallel, single phase 3-wire, and three phase operation options (expansion operation drivers). This allows the system to be used for large-scale EMC sitpoweror as test power for large-capacity industrial air conditioners.

Power line abnormality simulation

In AC mode, it is possible to simulate power line abnormalities by setting the output of the PCR-LE 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.

Power outages / increased voltage(pops) / decreased voltage(dips)

This system can simulate various conditions of phenomena occurring in AC power environments. It can be used for immunity tests of electrical and electronic devices which are connected to a low-voltage distribution system, or which have DC power input ports, under the standard conditions as specified on the right. The test conditons can be set outside the standard range, allowing the system to be used for preliminary tests prior to standard tests, immunity margin tests, and stress tests.

The PCR-LE2 Series is designed based on the PCR-LE Series which can switch between single-phase output, single-phase three-wire output*, and three-phase output by switching from the front panel operation. It contains the same basic features and performance of the PCR-LE Series, and uses the same power unit as the PCR-LE Series. Use of this series is much easier than installing individual single- phase, single-phase three-wire, and three-phase systems, and allows more effective use of space. The PCR-LE2 Series are available in 5 models: 6 kVA, and 9 kVA, and 12 kVA, and 18 kVA and 27 kVA.
