Isolated DC / DC converters have wide input voltage range, output voltage ripple of 50 mV minimum, Efficiency 82-92%，there are step-up and step-down the second largest category, stable and reliable performance. Output load is particularly applicable to more expensive devices, such as the control panel for electric forklift trucks, vehicles equipment, computers, audio control and so on. For example:

DC-DC step-up the converter;
Input voltage 12-24 volt, output voltage 13-60, output 5-100 watt. Dimensions 47 × 60 × 35mm. Weight 0.25 kg.USD$12.00/unit
Input voltage 12-24 volt, output voltage 13-60, output 5-200 watt, Dimensions 120 × 60 × 40mm,Weight 0.6 kg.USD$30/unit
Input voltage 12 volt, output voltage 24-60, output 500-1000 watt, Dimensions 150-230 × 100 × 55mm,Weight 1 kg.USD$130.00/unit

The special requirement can be made according to requirement after discussion.

DC-DC step-down converter;
Inputs 24 volt to output 12 volt output current 8A, output 100 watt, USD$10/unit 

Inputs 36-48 volt outputs 12-24 volt output 100 watt, 150W, USD$10/unit 

Inputs 36-48 volt outputs 12 volt output current 30A output 300 watt,USD$30/unit 

Inputs 36-48 volt outputs 5 volt output current 5A output 25 watt,（Isolated）

Dimensions 47 × 60 × 35mm USD$10/unit 

Inputs 80 volt outputs 24 volt output current 8A output 200 watt,（Isolated）Dimensions 120 × 60 × 40mm USD$30/unit 

Products with Input DC Larger than 60 volt,or I Larger than 30A,or special requirement can be made according to requirement after discussion.
