產品特點
概述
Reference 3000 恆電位儀的 Reference 30k Booster 是一款外部硬體選件,它可以使 Reference 3000 的電流限值增加 10 至 ± 30 A。 Booster 只能與 Reference 3000 一起運行,並且可以使用 Reference 3000 的所有功能,包括所有 Gamry 軟體和輔助電位計 (AE) 選件。 Booster 可替換 Reference 3000 的電流導線(輔助和工作),而 Reference 3000 的電壓感導線(包括 AE 的電壓感測導線)仍保持其原有的功能。
結合了 Reference 30k Booster 和 PWR800 電化學能軟體的 Reference 3000 是評估有關電池、燃料電池和下一代超級電容器的新技術的理想系統。 Ref 30k 的規定限制允許完全放電(至零伏),並且能夠精確測量 100 μΩ 以下的阻抗值。
Reference 30k Booster不僅限於高電流應用,其獨特的設計還允許直通式量測。這表示您可以使用 Reference 3000/3000AE 的 3 A、300 mA 和 30 mA 量程,同時仍連接到增壓器。我們的系統設計可挑選最適當的量程,讓您盡可能獲得最高解析度。

The Reference 30k™ Booster is ideal for higher current applications such as large format batteries and lead-acid batteries. It´s also ideal for fuel cell testing. Ground isolation allows for operation in parallel with a power supply or electronic load or grounded cells. The Reference 30K Booster attaches to a Reference 3000 Potentiostat or Reference 3000 Auxiliary Electrometer to bring the current limit up to ± 30 Amps with compliance limits of +20 and -2.5 V. This high current device features impressive bandwidth allowing EIS measurements up to 300 kHz.
System Highlights
Overview
The Reference 30k Booster for the Reference 3000 Potentiostat is an external hardware option which increases the current limit of the Reference 3000/3000AE to ± 30 Amps. It features a class-leading bandwidth of 300 kHz, allowing for high-frequency EIS measurements and rapid pulsing experiments. The Reference 3000 Potentiostat plus the Reference 30k Booster is an ideal system for the evaluation of new technologies for batteries, fuel cells, and next generation supercapacitors. The compliance limits of the Reference 30k allow complete discharge (through zero volts) and can accurately measure impedance values below 100 μΩ.
The Reference 30k is not only limited to high current applications but has been uniquely designed to allow pass-through measurements. This means that you can use the 3 A, 300 mA, and 30 mA ranges of the Reference 3000/3000AE while still connected to the booster. Our systems are designed to pick the most appropriate range, giving you the highest resolution possible.
Electrochemical Impedance Spectroscopy
The Reference 30K Booster is fully capable of performing electrochemical impedance spectroscopy. The shorted lead curve shown below is a measure of the limits of the instrument.
Rapid Pulsing
The booster's impressive 300 kHz bandwidth also allows it to do rapid pulsing experiments for techniques for cell characterization. As mentioned above, the system's response (including electrochemical cell) is dependent upon the instrument's internal resistances as well as the resistance of your cell. Below is an example of a 200 μs 12 A pulse on a 200 mΩ cell.
