DC/DC converters

Product catalog summary

Presentation
CRISTEC's switch-mode DC/DC converters are designed for powering electric and electronic equipment, ensuring high-quality output voltage and insulation. They can be directly connected to a battery, serving as a battery charger, and are easy to maintain due to their compact size and weight.

General Characteristics

Nominal Input Voltage: 12Vdc (10-18Vdc), 24Vdc (18-36Vdc), 48Vdc (36-72Vdc)
Output Voltage: 12, 24, or 48Vdc nominal, adjustable via external potentiometer
Output Power: 195W
Efficiency: 75%
Regulation: Line regulation at 1%, Load regulation at 2% (10-100%)
Dielectric Rigidity: Input/output > 1000Vdc
Cooling: Natural
Operating Temperature: 0°C to +50°C
Storage Temperature: -20°C to +85°C
Presentation: Enclosed box with screw terminal fixing
Input Protection: Against polarity reversal, EMI filter, fuses
Output Protection: Against short-circuit, overload by current limitation, overvoltage (Vnom + 25%)

Standards

Safety: EN 60950
EMC: EN 50081-2

Guarantee
2-year guarantee. Specifications may change without notice.

Typical Installation
DC/DC converters can be used with a 12V or 24V battery source, alternators, solar panels, or wind generators. They provide galvanic insulation with separate output and input minus and earth, suitable for DC power supply and battery charging applications.
