Step-up voltage regulator – Independant passive dissipation – Input 10V to 20V – Output 28V / 18A / 500W – SUR-1020-2818-2

Generates a stabilized 28V / 500W from a fuel cell having strong voltage fluctuations. Advantageously replaces conventional dc/dc converters (with high efficiency) when input/output insulation is not required.

Description

Input voltage: 10 to 20 V
Output voltage: 28 V
Output current: 18 A
Output power: 500 W
Efficiency: > 92%
Maximum leakage: 40 W

Advantages

  • Transforms for example a fuel cell into a battery charger under 28V / 500W
  • High efficiency allowing reduced dimensions and low weights
  • Wire loss reduction, in case of remote mounting (connections ≤ 72mm2)
  • Neutralized vibrations + tropicalisation + sealing: IP63 / IP67 casting
  • Scalable cooling options available, to push back the thermal limits

Mechanical data

  • Dimension: 92 x 64 x thickness 40 mm
  • Volume: 100 cm3
  • Weight: 290 g
  • High volume saving if the user already has a thermally dissipating functional wall
  • Connections through large streamlined clamps enabling wire sections up to 72mm²
  • Mounting possibility: with 2 screws on your thermally dissipating functional wall

Thermal characteristics

  • Temperature without derating: will depend on the thermal resistance of the user’s heat conducting wall
  • Temperature with derating: -40°C to +90°C (at decreasing power)
  • Storage temperature: -40°C to +100°C
  • Thermal resistance: 6°C / W
  • Temperature coefficient: 2.10-4 / °C
