Part number:1 Item Weight:100 g Product Dimensions:2 x 2 x 2 cm; 100 Grams Item Package Quantity:1 Batteries Required?:No Application: Widely used in intelligent ball bubble lamp power supply, intelligent household power supply, smart door lock power, bluetooth control power, beauty equipment, instrumentation, industrial control, LED lighting, industrial equipment, communications equipment, medical equipment, routers, iot, stage light power supply, home appliance control, etc.Specifications:Circuit board model: 30V 1.5APower protection: overload protection, safe area protection and other protection circuitInput voltage: AC 5-20VInput channel: 50Hz/60HZOutput voltage: DC 1.25V-30V(Continuous adjustable)Output current: Peak current 1.5A; Quiescent current 1mALoad adjustment rate: 25mVInput-output pressure difference: 2VWork Temperature: -25~85Work Humidity: 5%~95%RHSize: 77*42mmPackage List:1 X LM317 Adjustable Regulated Power Supply BoardNotes:1. Due to the difference between different monitors, the picture may not reflect the actual color of the item. We guarantee the style is the same as shown in the pictures.2. Please allow 1-2cm slight dimension difference due to different manual measurement. LM317 as A Good Regulator, With High Stability, High Temperature, High Linearity and Other Characteristics, the Output Voltage Range Up to 1.25V~37V Continuously Adjustable, the Maximum Operating Current of more Than 1A (using A Large Radiator Or Active Cooling Measures). The Board With A Rectifier Bridge, and With A 3300uF Filter Capacitor, Can Effectively Reduce the Output Ripple and Interference. Linear Voltage Regulator LM317 Voltage Regulator Module Can Stabilize the Input DC Voltage Output. The Output Voltage of LM317 Ranges From 1.25V to 30V, and the Maximum Load Current Is 1.5A. LM317 Built-in Overload Protection, Safety Protection and Other Protection Circuits. Typically, the LM317 Does Not Require External Capacitance, and the Output Capacitance Can Change the Transient Response. The Input Voltage and Output Voltage of the Module Need to Have A Certain Pressure Difference, Generally Greater Than 2V. This Upgrade Has Its Own Rectifier Bridge, 3A 1000V Voltage, Support AC Input.
