The NPS-W series is a three-window display mini DC power supply that simultaneously displays voltage, current, and power. This product improves the shortcomings of traditional linear power supplies that are bulky, heavy, and inefficient. Features: LED 3 digits display of voltage, current and power, high precision with single channel output. Voltage stabilization, current limiting, simple operation feature the DC power supply. Over voltage conservation(OVP), over current conservation(OCP) with over temperature conservation. Continuously adjustable output of voltage and current with fine regulating and coarse regulating. Automatic conversion of voltage stabilizing and current stabilizing, adopt current limiting conservation mode, and any external service state will not be damaged. With replaceable fuse for safe use, convenient to change the fuse. Applied in production line test, electrical maintenance, aging products, battery charging, laboratories scientific research and teaching and all other need DC regulated power supply.
