The PCR-WE/WE2 series from Kikusui can simulate power line abnormalities such as power outages, voltage dips and voltage peaks for testing power source switches and electronic devices and is aimed at testing electric vehicles (EVs), avionics, servers and power and EMC equipment.
The PWM inverter type range includes single phase versions (the PCR10000WE and PCR20000WE) or models with switchable single phase / single phase three-wire / three phase output (PCR30000WE2, PCR60000WE2, PCR120000WE2, PCR180000WE2, PCR240000WE2, PCR30000WE2 and PCR36000WE2). It supports mix-and-match parallel operation for large scale test systems up to 144 kVA (6 kVA models and above, with a maximum of four units).
These compact supplies are up to 60% smaller than Kikusui’s earlier PWM models, to occupy minimal space in a testing system, while efficiency has been increased by approximately 7%, to realise an overall efficiency of 85%. Power and energy density have been increased compared with the earlier PCR series. For example, the PCR60000WE2 (430 x 620 x 345mm or 16.9 x 24.4 x 13.5 inches) provides 6 kVA in a 4U unit.
The small form factor has been achieved without compromising ripple noise performance. The supplies have extremely low switching noise, with ripple noise as low as 0.25Vrms for the 1 kVA to 6 kVA models.
The output frequency of up to 5 kHz allows the sharp voltage fluctuations that occur in airborne electronic equipment testing to be simulated for use in avionic and defence markets. In addition, the 6 kVA / 6U form factor fits easily into an automated rack testing system without requiring space for an expensive, specialized power source installation.
The PCR-WE/WE2 series supplies have LAN, USB and RS232C interfaces, with a GPIB interface available as a factory option. The LAN connection is LXI-compliant, allowing the user to monitor and control the device from a computer, smartphone or tablet web browser. As well as flexible working, this feature is particularly useful when conducting AC tests in anechoic chambers or shielded rooms.
To save power, models rated 6 kVA and above have a sleep mode and a power saving mode.
