With a primary development concept of improved efficiency and low cost, the PCR-W/W2-Series, regulated AC power supply, features a balance of performance, function, quality, and cost based on the technology and know-how established with the PCR-L Series of products. Specifically, PWM inverter system was used for the power unit, providing the power supply with improved efficiency (by approximately 75 %), low-input current demand, and a considerably downsized and lightweight package design. The PCR-W/W2-Series power supply features a wide input range and high-quality, powerful output (as well as a reduction in low-waveform distortion, and the provision of high response speed and low power-factor load) for worldwide application, and is equipped not only with measurement and output capabilities for AC parameters such as RMS value, peak value, power, and power factor, but also with DC output and AC+DC output modes. With these features, the capabilities of the PCR-W/W2-Series power supply go beyond ordinary AC power supply, providing greater convenience.
Moreover, with one unit of the PCR-W2-Series product, utilization of both single-phase and three-phase outputs of the same capacity is possible simply by changing the position of the selector switch. This enables the user to eliminate installation of individual single-phase and three-phase systems as had previously been necessary, thus enabling the budget and space to be utilized more efficiently.
Low Noise and High Speed
High quality output like that of the linear amplifier system has been achieved: voltage waveform distortion less than 0.5%, voltage response speed of 60 µ s (standard value).
