Step-up voltage regulator – Standard passive dissipation – Input 10V to 14V – Output 28V / 18A / 500W – SUR-1014-2818-3

Able to generate a stabilized 28V / 500W from a battery of charging voltage 24V, this step-up regulator can advantageously replace conventional DC/DC converters (with much higher efficiency) when input/output insulation is not required.

Description

Input voltage: 10 to 14 V
Output voltage: 28 V
Output current: 18 A
Output power: 500 W
Efficiency: > 92%
Maximum leakage: 40 W

Advantages

  • Transforms a 12V battery into a powerful stabilized generator 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

  • Volume: 500 cm3
  • Weight: 700 g
  • Equipped with a dissipator 112
  • Connections through large streamlined clamps enabling wire sections up to 72mm²
  • 2 mounting possibilities: on DIN-rail with clip or on a wall with two screws

Thermal characteristics

  • Temperature without derating: -40°C to +30°C
  • Temperature with derating: -40°C to +90°C (at decreasing power)
  • Storage temperature: -40°C to +100°C
  • Thermal resistance: 1.5°C / W
  • Temperature coefficient: 2.10-4 / °C
