Used Dytran 4115B Current Source Power Unit Single Channel IEPE AC/DC (Working Pull) - ITEM#: 810013

---

Equip your test setup with this used Dytran Instruments Current Source Power Unit (Model 4115B). This line-powered, single-channel unit is designed to provide adjustable current and features a front-panel AC/DC coupling mode selector switch. This switch is highly useful for situations where DC coupling is not advisable, such as in thermally unstable environments.

When using IEPE sensors at very low frequencies (<5 Hz) or for quasi-static (close to DC) applications, the method of decoupling the sensor signal from the approximate +10 volt DC bias of the sensor amplifier can be a limiting factor in system low-frequency response. This unit helps manage those signals with a buffered output, an Output Zero adjustment knob, and an analog Sensor Bias Volts meter for easy visual monitoring. The rear panel is equipped with standard BNC jacks for the Sensor input and Output connections.

Condition & Testing Notes

Used - Untested (Working Pull). This unit was recently acquired from a fully operational facility that closed one of its locations. Everything we have sold from this specific facility so far has been in great working condition with zero returns, so we are highly confident in the quality of their equipment!

We do not have the specialized sensors or engineering expertise to power-test or verify the calibration of this specific unit. Because of this, we are selling it as an untested "working pull." However, we do offer our standard return policy if the unit does not meet your expectations when you integrate it into your system!

Cosmetically, the unit remains in very good, structurally sound condition, exhibiting typical minor wear expected from a working lab environment. Please review the attached photos closely to see the exact cosmetic condition and the front/rear panel layouts.
