Key Features
  • Isolated DC input and output
  • Designed for 72V DC locomotive and rail power systems
  • Regulated 24V DC output at up to 16A
  • Fanless design with no ventilation ports required
  • Electronic current sensing for overload protection
  • Automatically cycles the output during overload and resumes operation after the fault is removed
  • Compact enclosure suitable for flexible mounting positions
  • Suitable for loads with high surge current requirements, including lamps and motors
Professional Installation Requirements
  • Installation should be performed by a suitably qualified electrical or rail-systems technician. Follow the manufacturer's wiring, fusing, polarity, earthing and mounting instructions, and isolate the battery or DC supply before installation.
Applications
  • Locomotive and rolling-stock auxiliary power systems
  • Rail communications and control equipment
  • Vehicle electrical systems
  • Battery-fed 24V equipment
  • Industrial mobile machinery
  • High-surge loads such as lamps and motors
Environmental Benefits
  • Typically greater than 95% efficiency at full load, reducing conversion losses and operating heat
  • Fanless construction reduces auxiliary power consumption, noise and mechanical failure points
  • No ventilation ports required, helping reduce dust ingress and extend service life
  • Robust isolated design can reduce premature replacement and associated electronic waste
