30V 5A Bench Power Supply Yihua 305DA - 3 Outputs
Laboratory DC power supply Yihua 305DA
The series of single power supplies for currents up to 5A are reliable and precise laboratory equipment with regulated and stabilized DC voltage and regulated (limited) current consumption. The 305DA model can power up to three devices simultaneously with C.V. and C.C. The output voltage and current are smoothly regulated by the coarse and fine adjustment knobs separately for current and voltage; can operate in voltage (CV) or current (CC) output mode. The power supplies are protected against the effects of short circuits and thus against overload and damage. Cooling is provided by the built-in fan. They are equipped with 2 readable LED displays. The power supplies can be used in the design of electronics products, scientific works, in laboratories, on production lines and in teaching.
