Specificatii:
Input voltage: DC10V-70V;
Output voltage: DC5-58V continuously adjustable;
Applications where the adaptive input voltage is higher or lower than the set output voltage
Output current: 8A max, long time 6A max,do not allow the input and output current to work at the maximum value, and the sum of input and output currents cannot exceed 12A
Constant current adjustable: 0.5-8A
Output power: 180W max when working at low voltage, the maximum current is 8A.
The bare board has no auxiliary heat disipation.The maximum output is 30W.
The maximum output is 50W with a heat sink and no fan.
When the module temperature exceeds 65 degrees, heat dissipation is required
Standby current: about 20Ma
Conversion efficiency: about 90%
Input anti-reverse connection: None, please confirm the positive and negative before powering on
Dimensions: 70*52*21MM (bare board)
70*52*46MM (with heat sink and fan)
Weight: about 70g bare board, about 120g with heat sink, about 135g with heat sink and fan

Aceasta sursa nu suporta varfuri de curent mai mari decat cele specificati aici in detalii tehnice
Aceasta sursa nu suporta regim tranzitoriu (pornire/oprire) ale sarcinilor inductive al caror curenti (varfuri) depasesc specificatiile sursei => se va distruge!
Sarcini inductive: motoare, electromagneti, frigider auto, dozator apa . . . alte dispozitive
Prin diferite metode, se poate reduce efectele regimului tranzitoriu al sarcinilor inductive. De ex: O dioda rapida de putere polarizata invers, filtre RLC sau LC . . . (calculate la acel regim tranzitoriu)
