MP3020D Adjustable DC Power Supply 0-30V 0-20A Constant Voltage/Current OTP OPP

Durable construction: chassis made from high-class iron and plastic with a baking paint process for scratch and rust resistance, designed for long-term use. Efficient cooling: a built-in fan plus evenly spaced ventilation holes on both sides ensure continuous heat dissipation to extend service life. Precision performance: thoughtfully designed circuitry uses premium key components and operates in PWM switching mode to deliver stable, efficient output with fine voltage and current regulation—protecting sensitive parts and improving measurement and maintenance accuracy. Flexible controls: voltage is continuously adjustable from 0 to 30V and current from 0 to 20A with high resolution; both coarse and fine adjustment are available for rough or precise settings. Comprehensive safety: includes over-current protection, over-temperature protection, over-power protection, overvoltage protection, and a fuse. Intelligent operation: automatic switching between constant voltage and constant current modes occurs when the load reaches the set current, providing smart current limiting to prevent damage and ensure safe testing.
