SMAKN 150W Max8A 10-32V to 10-60V DC Buck Volt Converter Step Down 12V Car Power Supply Voltage Regulator Module properties: non-isolated module. Minimum voltage difference: 0V; --Input/output Voltage 1: When input is DC 12~32V, ouptput is12~60V((adjustable, default 19V); --Input/output Voltage 2: When input is DC 24~32V, ouptput is 24~60V(adjustable, default 19V). Input Current: 16A Max. ( exceed 8A please enhance heat dissipation); Output current: 8A; Max. (exceed 4A please enhance heat dissipation. Quiescent operating current: 15mA (12V to 20V, higher output voltage will increase the quiescent current); Output power: 90W(natural cooling), 150W(enhance heat dissipation );Operating temperature: -40~ +85''C. Working frequency: 150KHz; Conversion efficiency: up to 95%. Operating indicator: Yes;
