PCR-WEA/WEA2

Ultra-Compact AC/DC Programmable Power SupplyPCR-WEA/WEA2 Series

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 input. For regeneration within the installation site only. *2 Parallel operation is available for 6kVA models and up, with a maximum of 4 units. Same model combination is not required.

Built-in parallel operation driver software!
Easy parallel operation with a single connection cable.

The PCR-WEA/WEA2 series can be easily configured in a parallel connection with a single cable * per connection for all models 6kVA and above. This cable can be used in synchronization with a power-interlock cable* to control the ON/OFF status of master/slave units. * Optional

Up to 144 kVA with Parallel Operation

Mix-and-match parallel operation

Parallel operation is possible with a maximum of four units of 6kVA or higher models, and different models can be combined as long as they have the same input voltage.
