A COMpACT pOwER SupplY RANGE fOR TESTING ApplICATIONS
The Kikusui PCR-WE/WE2 series of multi-functional switching AC power supplies, available from Telonic Instruments, range from 1kVA to 36kVA AC/DC output with frequency conversion from 1Hz to 5kHz. They can simulate power line abnormalities such as power outages, voltage dips and voltage peaks for testing power source switches and electronic devices. They are well suited to a wide range
of diverse market segments: electric vehicles (EVs); plug-in hybrid vehicles (PHVs); avionics; servers; power and EMC equipment.
This series 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). The PCR-WE/WE2 series supports
mix-and-match parallel operation for large scale test systems up to 144kVA. These compact supplies are up to 60
per cent smaller than Kikusui’s earlier PWM models, to occupy minimal space in a testing system, while efficiency has been increased by approximately seven per cent, to realise an overall efficiency of 85 per cent. 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 6kVA in a 4U unit. The small form factor has
been achieved without compromising ripple noise
SMARTER CONDITION AND ENERGYMONITORING
ifm electronic’s Smartobserver software enables users to condition data acquisition primarily to see what is actually happening on their manufacturing plant right down to individual sensor level and then store that data for analysis later. At the heart of Smartobserver is the LR agent CP
which is the key to collecting data and is essentially configurable, bio-directional communicating interface software. It collects and handles the information from the machines in the manufacturing process and transmits it to other systems. In addition, LR Agent CP can send the required information back to the machines in the process. The fundamental benefits of using Smartobserver
12
is that it provides operators with details of the bigger picture with an analysis of what is actually occurring in their process driven by direct data collected from the sensors in their plant. Therefore, relying on historical data for estimations becomes unnecessary and irrelevant. The result is improved condition monitoring of machines and installations, better analysis of energy consumption and optimum quality control of the processed products. To sum up the key features of Smartobserver and
what they represent are; continuous condition monitoring of machines and systems, trend analysis, representation of limits and evaluation of all process parameters, data collection of all available
parameters, visualisation and evaluation with trend display for pressure, flow, temperature, current and rotational speed. Also if required, changing operating condition of machines, data provision for more sophisticated systems such as ERP, SAP, HANA, MII, ME and alarm escalation chains.

performance. The supplies have extremely low switching noise, with ripple noise as low as 0.25Vrms for the 1kVA to 6kVA models. An output frequency up to 5kHz.
allows the sharp voltage fluctuations, required 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, specialised power source installation. These versatile 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.
