KPS3040D Product description 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. Features •Small size, light weight, suitable for work surface use and rack installation; • Exquisite appearance, flexible operation and convenient use; •High precision, internal use original chip, stable and reliable performance; •Using high-gain amplifier circuit design, with good fast load transient response to prevent unwanted voltage offset; • Using PWM modulation, high efficiency, more power saving; •Intelligent temperature control fan with low noise • Built-in OVP over-voltage protection, OCP over-current protection, OPP overload protection, OTP over-temperature protection, complete and reliable protection functions; • Voltage and current preset, OUT output function • The product has a short-circuit protection alarm function Application field Electrolytic plating Product aging test Production line test Charging batteries Electronic device testing Laboratory research and development test School teaching experiment Telecom Power Operation requirements Input voltage： AC220V±10%.
