Step-up voltage regulator – Dynamic dissipation – Input 54V to 69V – Output 72V / 18A / 1296W – SUR-5469-7218-1

Powered by three 450W photovoltaic panels “18V / 23V” connected in series, this step-up regulator replaces (with very high efficiency) conventional dc/dc converters when input/output insulation is not required.

Description

Input voltage: 54 to 69 V
Output voltage: 72 V
Output current: 18 A
Output power: 1296 W
Efficiency: > 97%
