VarTech’s Rugged

Harsh Duty Power Supply

VarTech’s harsh-duty fully-encapsulated ultra compact high-density and efficient DC/DC converter features wide input voltage ranges, remote sense, enhanced output programmability, and low standby dissipation.

FEATURES:

  • Wide Input Voltage Range: 9 to 36 VDC
  • Fully encapsulated for protection in harsh environments
  • RoHS compliant
  • cULus, cTÜVus
  • CE Marked
  • Output overvoltage protection & thermal shutdown
  • Remote sense and current limit
  • Logic disable
  • Wide range output adjust
  • ZCS power architecture, the latest in advanced power conversion topology using zero-current switching which operates with a high fixed switching frequency.
    Noise (electromagnetic interference, or EMI) can vary widely among DC-DC converters from supplier to supplier and topology to topology. The reasons for this are diverse, but they include fundamental differences in the way noise is produced. A major difference, for example, between fixed frequency pulse-width modulated (PWM) and variable frequency zero-current switching (ZCS) converters is the noise generated by the switch. Among other reasons (because ZCS converters have sinusoidal waveforms rather than square waveforms), the lack of sharp edges and lower harmonic content results in much less excitation of the parasitic elements, resulting in far less noise.
  • Low noise FM control
  • An advanced architectural arrangement which further minimizes noise, eases regulation, gives greater dynamic performance, avoids inductance problems associated with long leads, and minimizes the need for sense lines
  • Extended Operational Temperature Capabilities: -45C to +100C
  • Zero-current-switching forward converter technology
  • State-of-the-art power density with maximum efficiency
