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
