Phase current measurement module reduces total IPC costs

A new IPC Modular measurement module for phase current measurement has been unveiled by Isabellenhütte. The new device has been boasted to considerably reduce the total IPC costs with its brand new delta-sigma modulator. Available in previous models, the company now runs a new variation of the modulator for analogue/digital conversion that offers additional functions that allow users to solder fewer components on the circuit board. Furthermore, the IPC is completely galvanically isolated.

The new current measurement module is also isolated up to 1,400V. 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.

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. 75Ksample/s and can also be supplied with optional over-current 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.
