Step-up voltage regulator – Independant passive dissipation – Input 18V to 23V – Output 28V / 25A / 700W – SUR-1823-2825-2

Generates a stabilized 28V / 700W from the charging voltage of a 24V battery. Advantageously replaces conventional dc/dc converters (with higher efficiency) when input/output insulation is not required.

Description

Input voltage: 18 to 23 V
Output voltage: 28 V
Output current: 25 A
Output power: 700 W
Efficiency: > 95%
Maximum leakage: 32 W

Advantages

  • Transforms a powerful solar panel into a 700W generator stabilized at 28V
  • 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
