Pulse Electronics
Current sense magnetics are used as a low loss method for sensing AC current in a circuit and also provide electrical and safety isolation between the source of the current and the measurement circuit. The key parameters for a current sense transformer are the rms current rating (to ensure it does not overheat in the application) and the safety and voltage isolation (to ensure it conforms to the end-application requirements).

DT4 -
North Atlantic Industries
The DT4 module (the enhanced version) features 24 programmable channels for either input (voltage or contact sensing with programmable, on-module pull-up/pull down current sources), or output (current source, sink, or push-pull) up to 500 mA per channel from an applied, external 3 – 60 VCC source. These modules can sense broken input connections and whether an input is shorted to +VCC or to ground. Additional features of the DT4 (Enhanced Version) are listed below.

Keysight Technologies
The Keysight Mobile Communications DC Source 663xx series offers several features ideal for testing wireless and battery powered devices. Excellent voltage transient response ensures maximum test-system throughput by minimizing device shutdowns due to significant voltage drops in the test wiring. Built-in advanced measurement system to accurately measure battery current drains when the device operates in different modes and a Keysight-developed feature that enables cellular telephone manufacturers to detect permanently and intermittently open-sense wire connections. The Keysight 66332A Dynamic Measurement dc Source provides dynamic measurement and analysis of voltage and current waveforms. It is ideal for testing digital wireless communications products/components because it not only provides the power for testing, but also performs the peak current measurements required to characterize the pulsed current demands of these products.

ProDAQ 5821 -
Bustec Ltd.
The ProDAQ 5821 series of Signal Conditioning Cards is designed to interface with a variety of sensors, principally RTDs, Thermistors, Cryogenic Diodes and Voltage type sensors. Each version of the 5821 provides the capability of precise 4-wire measurement. In order to achieve this, a precise 500μA constant current source is provided per channel. The current source can be disabled on a per channel basis and is monitored to ensure that current is flowing. The value of the output current is stored on-board after calibration. In order to achieve the highest accuracy the output current may be automatically calibrated 'on-the-fly' using the ProDAQ 3416 24-bit Sigma-Delta ADC card and an on-board precision resistor.
