Key Features
  • Regulated 24V DC output at up to 2A
  • Wide 55–90V DC input range for 72V nominal systems
  • Galvanically isolated input and output
  • Suitable for locomotive, vehicle and battery-fed applications
  • Frequency-proportional V-F output for battery monitoring and telemetry
  • Fanless operation without external cooling fins or ventilation ports
  • Electronic overload protection without an output fuse
  • Designed for installation in restricted-airflow positions
  • High efficiency to reduce heat generation
Professional Installation Requirements
  • Installation should be performed by a suitably qualified electrical, vehicle or rail technician. Use correctly rated DC cabling, input protection, isolation and earthing/bonding arrangements appropriate to the vehicle or rail system, and follow the manufacturer's wiring instructions.
Applications
  • Locomotive and rail vehicle equipment
  • Vehicle electrical systems
  • Battery-fed control and communications equipment
  • Industrial telemetry and battery monitoring
  • 72V nominal DC systems requiring an isolated 24V supply
  • Equipment installed in restricted-airflow enclosures
Standards & Compliance
  • AS/NZS 3820: Relevant essential safety requirements framework for electrical equipment supplied in Australia; product-specific Australian compliance documentation was not located.
  • AS/NZS 3000: Relevant installation reference where the converter forms part of an Australian electrical installation; product-specific compliance was not verified. ([eess.gov.au](https://www.eess.gov.au/safety-requirements/relevant-standard/?utm_source=openai))
Environmental Benefits
  • Typically greater than 90% efficiency at full load reduces conversion losses and heat generation.
  • Fanless construction can reduce auxiliary energy use and maintenance associated with cooling fans.
  • No ventilation ports help reduce dust ingress and may support longer service life in enclosed equipment.
  • Electronic current limiting and robust isolated construction may reduce premature replacement and electronic waste.
  • Suitable for battery-fed systems where efficient DC power conversion can help conserve stored energy.
