Current Source Power Unit 4103C

Model 4103C is a 3-channel, battery operated portable current source power unit. It is designed to operate with IEPE accelerometer, pressure transducers and force sensors which contain integral amplifiers.

The Dytran 4103C model is a current source power unit.

Firstly, IEPE sensors require a source of constant current. This is usually in the range of 2 to 20mA at supply and a voltage range of +18 to +30 VDC.

Secondly, the current source power unit supplies a fixed constant current to the sensor of 2 mA at +18 volts compliance level. Power to operate the sensor is by 2 x 9 volt dry cell batteries. To produce +18 Volts DC. A low current voltmeter located on the from panel of the 4103C constantly monitors the voltage appearing at the “sensor” jack. This DC voltage is used for testing faulty operation of cables and sensors. A push button located below the meter checks battery voltage without disturbing test in progress. Also both sensor and output jacks are BNC.

Features include:

  • Designed to operate with IEPE accelerometer, pressure transducers & force sensors with integral amplifiers
  • Battery powered
  • Portable
