Step-up voltage regulator – Standard passive dissipation – Input 45V to 56V – Output 58V / 40A / 2320W – SUR-4556-5840-3

Able to stabilize at 58V / 2320W the voltage from a 56V / 700W battery, this step-up regulator can advantageously replace conventional dc/dc converters (with very high efficiency) when input/output insulation is not required.

Description

Input voltage: 45 to 56 V
Output voltage: 58 V
Output current: 40 A
Output power: 2320 W
Efficiency: > 98%
Maximum leakage: 30 W

Advantages

  • Transforms a 48V battery into a powerful stabilized generator 58V / 2320W
  • 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

Specifications

Protections

  • Limited overloads: as long as decreasing Vout remains ≥ Vin + 0.5V
  • Abnormal overloads: please add a fuse or current-limiter on the output or input
  • Under-voltage or sufficient input over-voltage: the regulator no longer elevates the input voltage
  • Filters: input and output; shields: two parallel metallic plates
  • Thermal protection: lowering of Vout to # Vin – 0,5V (automatic reset)
  • Vibrations, tropicalisation, sealing: iP63 to iP65 casting
  • Stainless steel for the clamping braces
  • Ohmic wire loss reduction, with connectors receiving sections up to 72mm2

Standards and specifications

  • Marking CE/UL 60950-1 / EN 60950-1 / iEC 60950-1 / RoHS / 55022A if optional external filter
  • Flammability: horizontal test for electrical applications, according to UL 94 HB standard
  • Worldwide manufacturers for active parts. Patent, assembling and final controls: Elecdan Converter
