Module Type: Synchronous rectification non-isolated step-down constant current, constant voltage module Constant voltage and constant current output continuously adjustable Output voltage: continuously adjustable (1.2-35VDC) for a long time below 32V (applicable to applications where the input voltage is higher than the output voltage and cannot be boosted) Working frequency: 150KHZ Output ripple: Ripple around 50mV (no noise) 20M bandwidth (for reference only) 24V input measured Working temperature: -10℃ to +75℃) Potentiometer adjustment direction: clockwise-(increase), counterclockwise-(decrease) Output short circuit protection: Yes (instantaneous protection) constant current (current setting constant current value can notbe short-circuited for a long time) Input reverse protection: None. Scope of application: DIY, Hobbyist, High-power LED constant current drive, Battery charging, Solar etc. * The buck module has 2 heat sink that could enhance heat dissipation, extending service life. * When there is a big difference between input and output voltage, please decrease power and current.
