Step-up voltage regulator – Reinforced passive dissipation – Input 20V to 28V – Output 36V / 20A / 720W – SUR-2028-3620-4

Able to generate 36V / 720W from a 24V battery, this step-up regulator can advantageously replace conventional dc/dc converters (with higher efficiency) when input/output insulation is not required.

Description

Input voltage: 20 to 28 V
Output voltage: 36 V
Output current: 20 A
