DH7002A Electrochemical Workstation Introduction: The DH7002A comes standard with a maximum output current of ± 4A and can be extended to ± 30V or ± 20A, providing a more suitable choice for high current/high voltage users. Features: 1. High current -The high current range of 4A to+4A can be extended to ± 30A, providing more suitable choices for high current users, especially as an excellent tool for evaluating fuel cell efficiency 2. High sampling rate Can be used for rapid cyclic voltammetry, rapid potential/current pulses, or pulse discharge testing of mobile phone batteries 3. Infinite channel expansion Multiple DH7002As are combined into a multi-channel system through Ethernet switches or routers, which can be infinitely expanded. Through a single computer, all channels can be controlled for synchronization experiments 4. Power expansion Multiple power amplifiers can be connected externally through multi-core, high insulation impedance rectangular connectors, with software automatic recognition, intelligent and convenient Technical parameters: Number of channels: single channel Output voltage range: ± 15V Applied/measured potential range: ± 10V Applied/measured current range: ± 4A Applied potential accuracy: 0.1% x full scale reading ± 1mV Applied potential resolution: ± 100mV (3 μ V) ; ± 1V (30 μ V) ; ± 10V (300 μ V) Measurement potential accuracy: 0.1% ± 1mV of full scale Measurement potential resolution: 760nV Applied current accuracy: Readability accuracy: ± 0.1% Applied current resolution: 1/30000 * full range Measurement current accuracy: ± 0.1% reading ± 1pA Measurement current resolution: 8pA (1) μ A range) Current level: 1 μ A-4A, fully automatic range Constant potential bandwidth: 2MHz Switching speed: 10V/ μ S Rise time: ≤ 500ns Differential electrometer bandwidth: ≥ 10MHz Input impedance: ≥ 1012 Ω Leakage current: ≤ 1pA IR compensation: positive feedback or dynamic iR compensation Impedance frequency range: 10 μ Hz~1MHz Impedance amplitude: 0.1mV~1V RMS Impedance scanning method: linear or logarithmic Electrode connection method: two, three, or four electrodes Communication interface: Ethernet Voltage: 220V
