The Tenma 72-7245 is a 2-channel, 180W output, linear DC power supply. Overload and reverse polarity protection and an output on/off switch keep the product and its load safe from unexpected conditions. A High regulation (0.01%+3mV) and low ripple/noise (< 1mVrms, 5Hz~1MHz)are maintained for channel 1 and 2 in constant voltage mode. Automated cooling fan speed control minimizes fan noise according to load conditions, ensuring quiet operation. The product is an ideal solution for lightweight, inexpensive bench-top or portable applications requiring high regulation and multiple outputs.
