We produce this as common products for 24Vdc to 12Vdc with 10A output converter. DC/DC convertors 24V-12V,12V-5V Power? currency? $3.00U.S./unit Rises to press/Falls presses the DC-DC converter. Input output voltage 12-72V, output 5-300W, the user may choose voluntarily. Has short-circuits, has flowed and so on the conventional protection, has low characteristic and so on ripple, high efficiency. DC-DC Rises to press the converter; Input voltage 12V, output voltage 24V, output 100W. Input voltage 12V, output voltage 36, 48V, output 50-200W The special requirement can be made according to requirement after discussion. DC-DC falls the profiling converter; Inputs 24V to output 12V output current 8A, output 100W, $3.80U.S./unit Inputs 36V, 48V outputs 12, 24V output 100W, 150W, $3.60U.S./unit Inputs 36, 48V outputs 12V output current 30A output 300W,$25.00U.S./unit Products with Input DC Larger than 60V,or I Larger than 30A,or special requirement can be made according to requirement after discussion.
