Isabellenhütte unveils new phase current measurement module with brand-new components at PCIM

Isabellenhütte has unveiled its new IPC Modular measurement module for phase current measurement with enhanced components at the PCIM Europe international conference in Nuremberg. The new device can reduce the total IPC costs considerably. One of the factors behind the reduction in costs is the brand-new delta-sigma (?S) modulator. This was available in previous models, but now Isabellenhütte is using a new variation for analogue/digital conversion that offers additional functions. “The new IPC’s ?S modulator has an array of additional features that allow us to solder fewer components on the circuit board,” says Athier J. Lafta, Product Manager at Isabellenhütte. Furthermore, the IPC is completely galvanically isolated.
Another important feature of the new IPC is the non-volatile electronic memory which automatically calibrates the phase current measurement module. “That saves customers time and money,” says Athier J. Lafta.

Fully configurable and with internal isolation up to 1,400 V

The new current measurement module is also isolated up to 1,400 V. As a result, the IPC can be used universally to detect phase current in industrial environments and also to measure current in AC/DC converters that require a high degree of isolation. “Thanks to the higher level of isolation, we can provide a current measurement module for phase current detection precisely according to customer requirements,” explains Athier J. Lafta. In view of specific requirements regarding phase current measurement, it’s not just the fully configurable isolation that is attractive for customers. Isabellenhütte also offers the IPC as a modular component: In terms of communications, customers have the choice between a number of different interfaces such as the RS-485 or the optical UART interface. With filters, the system can measure values from sources of up to approx. 75 Ksample/s and can also be supplied with optional overcurrent detection. A serial 1 Bit data stream with 20 Mbit/s maximum is possible without filters. Based on shunt technology, the IPC can measure continuous current ranging from 150 to several thousand amperes.
