The NPS-W series is a three-window mini DC power supply that simultaneously displays voltage, current and power. This product corrects the disadvantages of traditional linear power supplies that are bulky, heavy and inefficient. Features: 3-digit LED display of voltage, current and power, high precision with single channel output. Voltage stabilization, current limitation, simple operation is characterized by DC power supply. Overvoltage protection (OVP), overcurrent protection (OCP) with overheating protection. Smooth regulation of voltage and output current with accurate and coarse adjustment. With replaceable fuse for safe use, convenient to replace the fuse. Used in production line testing, electrical maintenance, aging products, battery charging, scientific and teaching laboratories and we all other cases requiring DC regulated power supply.
