Power Supplies for Simulating Various Power Line Abnormalities

Power supplies for evaluating single-phase and three-phase input devices can simulate power line abnormalities such as power failure, voltage drop/rise, and frequency fluctuation of commercial AC lines.
A single PCR-WEA/WEA2 series unit can switch between single-phase, single-phase 3-wire, 3-phase 3-wire, and 3-phase 4-wire *. In the case of 3-phase input, this series can reproduce a 3-phase imbalance or simulate abnormalities such as momentary power loss of only one of the three phases. Using the PCR-WEA/WEA2 series in combination with a dedicated software enables PC-based test configuration and execution, simplifying input voltage fluctuation testing.
*Applies to models of 3 kVA or more.

Optimal Power Supply Solutions for Evaluating Consumer Electronics Worldwide

The PCR-MA series, which outputs clean and stable AC voltage, is recommended for power measurement of consumer electronics used in many countries around the world, such as hair dryers and microwave ovens.
The output voltage varies from 0 to 310 Vrms, and the frequency ranges from 40 to 500 Hz. Therefore, the output voltage can be set to match the power supply conditions in different countries, such as 100 VAC or 220 VAC.
When combined with power meters or other devices, this series can also be used to measure standby power.

IEC61000 Compliance Testing System

This system can simulate various phenomena in an AC power supply environment. It can be used for immunity testing of electrical and electronic equipment connected to low-voltage power distribution systems, as well as electrical and electronic equipment with DC power input ports. Test conditions can be set outside the standard range and used for preliminary testing before standard testing, immunity margin testing, and stress testing.

Furthermore, by combining the KHA series of harmonic/flicker analyzers with application software, the PCR-WEA/WEA2 series, the PCR-LE/LE2 series of stabilized AC power supplies, and the LIN series of linear impedance networks, tests can be performed in accordance with IEC and JIS standards.
