Grau Elektronik has introduced its DC / DC Converter KLB for 24V / 600V, 110V / 600V, 24V / 1,000V and 110V / 1,000V applications.

In special cases that primary energy is not available for some time, it is necessary to have a substitute energy system for emergency operating actions. These can be carried out by charging a capacitor bank as long as the primary system is active.

Grau Elektronik’s DC / DC converter offers the following features:

  • Compliant with IEC 50155 and EN 50121-3-2 standards
  • TA: -40°C-70°C (10min 85°C)
  • VIn: 66V-154V or 14.4V-33.6V, VOut: 400V, 600V or 1’000V
  • Continuously no load and short-circuit proofed
  • Pout for fast charging up to 2kW
  • Robust and reliable
  • High frequency 100kHz POWER MOSFET technology
  • Output voltage monitor
  • V2A steal housings designed for chassis (wall) mounting applications
  • PCB: FR4, V0, TG: 150°C
  • MTBF: 500’000h, TA: 40°C nominal load (Siemens Norm (SN) 29500)
  • Input to output with high galvanic isolation
  • Output decoupling diode and output fuse
  • Output with included di/dt slow-down
