Adjustable Digital DC power supply 30V 20A Laboratory Switching Power supply 110v-220v PS3020 laptop phone repair Rework

Model: PS3020 Input voltage: AC 220V 50HZ Output voltage: 0-30V Output current: 0-20A Ripple and noise: (0-30V) ≤ 100MVP-P (50HZ ~ 20MHZ) Load effect: 1X10 + 20MV Protection: current limiting protection, overheating protection Voltage indication accuracy: 1%. The last digit is one word apart Current indication accuracy: 2%. The last two digits differ by two words Fuse: 5A Weight: 3.0KG feature: 1. Switching power supply design, stable and reliable, light and beautiful, using SMT production process. 2. With backlit LCD display output, the voltage can be adjusted accurately using a multi-turn potentiometer. 3, constant voltage, constant current automatic conversion, can be used as a constant voltage source, can also be used as a constant current source. 4, the circuit design is reasonable, the key components are imported, can be used at full load for 24 hours. 5, PWM switching mode, high efficiency, energy saving, environmental protection, performance close to linear power, efficiency is much higher than linear power, in most cases can replace linear power. 6, intelligent temperature control fan (can work at temperatures up to 50 ° C), effectively reduce noise and extend the life of the fan. 7, current limiting protection Scope of application: 1.Aging of factory products: such as aging of DC motor, DC motor, DC fan, car DVD, car audio, resistor, capacitor, etc. 2. Battery charging industry: Perfectly used in the battery charging industry, it provides constant current charging and then converts to constant voltage trickle current charging to prevent overcharging, protect the battery, and effectively extend battery life. 3. Inverter industry: It avoids the problem of potential poor contact during linear power relay transition, extremely fast response speed, and meets the load requirements of instantaneous changes. 4. LED manufacturing: LED module testing, aging. 5. Solar Panel Test Kit 6. Everything else needs a DC regulated power supply
