The frequency-pulse supply is a separate QEEHUA power-equipment family. A pulse-process enquiry needs more than average current: define the intended waveform, timing and control requirements with the process engineer. State the bath application and the required interface to the production line. Ask QEEHUA to confirm the proposed output configuration and how it will be demonstrated at acceptance. The related application reading is an enquiry reference and does not establish a pre-approved configuration. Official product specifications.
