Price: [price_with_discount]

KPS series products are a high-power digital display program-controlled switching DC regulated power supply newly developed and upgraded by our company. This product is a DC programmable power supply with exquisite appearance, small size, high performance, powerful function and simple operation. It is suitable for testing in aerospace and defense, consumer electronics, computers and peripherals, communications, semiconductors, solar energy and automotive electronics. The product can display voltage and current at the same time. The output voltage and output current are adjusted by the encoder knob, which can be continuously adjusted between 0 and the nominal value. It has high power, large current, fast response, and fast load transient response, Low noise, easy to use and other significant advantages! The stability and ripple coefficient of the power supply are very good. It has various protection circuits such as short-circuit protection, over-voltage protection, over-current protection, over-temperature protection, etc., which can work at full load for a long time and is deeply loved by users.
