Electrophoresis Power Supply (Programmable)
2 de agosto de 20260
Product overviewThis product is a rectifier device that converts alternating current into direct current. It can convert alternating current into controllable constant voltage and constant current direct current to meet the needs of experimental production such as electrophoresis. It is widely used in biology, medicine and other fields, such as nucleic acid gel electrophoresis, Protein gel electrophoresis, Western Blot protein transfer and other experiments. Product advantages1. It can be fine-tuned online in real time in the working state;2. Intelligent PID control, stable and reliable output;3. High-definition LCD screen, which can display setting parameters and display real-time voltage and current values;4. High precision;5. With constant voltage timing, constant current timing, gradient voltage programming, gradient current programming and other working modes;6. Adopt forward switching power supply design with good stability. With overvoltage, overcurrent, overload, variable load, no-load protection, automatic alarm protection for abnormal conditions;7. The upper limit of output voltage or current can be dynamically set;8. The parameters can be remembered when the power is cut off. The equipment is accidentally cut off. After power-on, the unfinished setting program can be automatically run. Technical parameters1. Input power: 180V-240V2. AC frequency: 50Hz/60Hz3. Ambient temperature: 4°C-40°C4.
