Step-up voltage regulator – Reinforced passive dissipation – Input 36V to 46V – Output 56V / 12.5A / 700W – SUR-3646-56-12.5-4

Generates a stabilized 56V / 700W from the charging voltage of a 48V battery.
Advantageously replaces conventional dc/dc converters (with higher efficiency) when input/output insulation is not required.

Description

Input voltage: 36 to 46 V
Output voltage: 56 V
Output current: 12.5 A
Output power: 700 W
Efficiency: > 95%
Maximum leakage: 32 W

Advantages

  • Transforms a solar generator into a 28V / 700W battery charger
  • 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

Mechanical data

  • Volume: 1000 cm3
  • Weight: 1150 g
  • Equipped with a dissipator 225
  • 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 +50°C
  • Temperature with derating: -40°C to +90°C (at decreasing power)
  • Storage temperature: -40°C to +100°C
  • Thermal resistance: 1°C / W
  • Temperature coefficient: 2.10-4 / °C
