PWM Inverter Type – Programmable AC Power Supply The PCR-WEA/WEA2 Series brings new innovations to the power-electronics industry.

The PCR-WEA/WEA2 is a series of multifunctional switching AC power supplies that combines accurate, high-power output with an ultra-compact design. The 15 model line-up ranges from 1 kVA to 36 kVA AC/DC with single & 3-phase variable output from 6 kVA and up. The PCR-WEA2 also features a regenerative mode*1 that can drastically reduce power consumption and cut operating costs. The PCR-WEA2/WEA2R also supports mix-and-match parallel operation*2 up to 144kVA for large-scale test systems. Output frequency up to 5kHz is also available with all models, which is critical for AC applications in avionic industries.*1 Only “R” models (PCR-WEA2R) with 3-phase 200 V/400 V input. For regeneration within the installation site only. *2 Parallel operation is available for 6 kVA models and up, with a maximum of 4 units. Same model combination is not required.


Compared to our previous PWM models, the size of the PCR-WEA has been drastically reduced by 60%. Efficiency has also been increased by approximately 7%, for an overall high efficiency of approximately 85%.

Significantly more compact than Previous model*.The larger the capacity model, the greater the effect of space saving.* PCR-W/W2 series

The PCR-WEA/WEA2 series 6KVA models have a space-saving design that can fit in a rack (6U), while conventional models require more space for installation.

Approx. 7% higher efficiency

By adopting the PWM inverter method for the power unit part, a high efficiency of 85% was achieved.
