WPS3010B DC Power Supply USB Powered Adjustable Programmable Switching Power Supply for Laboratory 10A 300W

Feature: 1. WPS3010B 10A 30V 300W digital display programmable switching DC regulated power supply, which can display voltage, current and power at the same time. 2. It is suitable for product aging, research and development tests, schools and production lines. The output voltage and output current are preadjusted by the encoder knob, which can be continuously adjusted between 0 and the nominal value. 3. The stability and ripple coefficient of the power supply are very good, with various protection circuits such as short circuit protection, over voltage protection, over current protection, and over temperature protection. 4. The design is artistic and easy to operate, and it can work at full capacity for a long time. This machine is equipped with a USB power supply interface and a computer PC software control function. 5. Durable, made of high quality sheet metal + ABS material, not easy to damage, long service life, and can be used for a long time.

Package List: 1 x DC Power Supply1 x Power Cord1 x Load Cord1 x Manual Note: 1. Please use a power cord that meets the power requirements of this product.2. Before use, the power supply must be grounded reliably, and the weak leakage current caused by the internal anti‑electromagnetic interference circuit of the power supply should be led to the ground, otherwise false leakage will occur, which may cause damage to the load equipment or cause the power supply to resist interference Decrease in ability.3. When using this power supply to charge reusable batteries (such as ‑acid batteries), you must ensure that the positive and negative poles of the power supply are correctly connected to the positive and negative poles of the battery. If they are connected reversely, the internal rectifier components of the power supply may be burned out. , Or damage the load equipment.4. It is strictly forbidden to use this product in an environment with flammable, explosive materials, humidity, and corrosive gas.5. When this product is working, it will generate heat, especially when it is used at full power. Therefore, please use this product in an environment with good ventilation and heat dissipation, and ensure that there are no other obstacles in the vicinity of the product s cooling fan and vents.6. When using this power supply, please select an output wire with sufficient wire Diameter according to the output current of the product. The connection area between the wire and the power supply, the wire and the load equipment is large enough, the contact surface is clean and free of corrosion, and the connection must be firm to avoid heat damage to the terminal or load equipment, which may cause a fire in severe cases.
