Isabellenhutte unveils current-measurement modules

Isabellenhutte is presenting the IPC series of current-measurement modules for the motor-phase current on measurement shunt basis at the PCIM and Sensor+Test trade fairs.

The modules are designed to control electric high-performance motion-control units of all types.

The data acquisition runs at sampling rates from 10 to 300kHz.

A programmable sampling delay time triggered with an external signal is supported.

The modules also supply a fast over-current signal (response time less than 2usec).

The IPC series features a modular structure.

Currents from 20A up to several thousand amperes can be measured by matching the shunt value.

For example, a continuous current measurement of 5kA can be realised by using a 2uOhm shunt.

All IPC modules are galvanically isolated and highly dynamic, providing accurate measurement and a resolution between 12 and 16 bit.

An integrated modulation unit processes the current value signals under consideration of the calibrated parameters.

The resulting digital signal is transmitted, potential free, over various interfaces.

It can be processed directly by motor controller via a digital input.

Further advantages of the current-measurement modules are the low ohmic shunts that reduce power loss, low offset and drift, as well as the reduced noise level.

In addition to general industrial applications, the IPC series may be used in AC/DC current measurement for drive technology; inverter/solar technology and UPS systems.
