Robust Power Electronics for Modern Industrial DC Micro-Grids

Industrial manufacturing and energy distribution infrastructure are rapidly shifting toward high-voltage DC backbone networks (DC Mini-Grids / Micro-Grids). Operating directly from 450VDC, 600VDC, or 820VDC intermediate circuits, CAMTEC HSD series DIN-rail DC/DC power supplies eliminate continuous AC-to-DC conversion losses while delivering ultra-stable regulated 12V, 24V, 36V, 48V, 60V, or 72V output voltages.

Designed for demanding environments in automation, photovoltaic integration, battery energy storage systems (BESS), and electric vehicle charging support infrastructure, CAMTEC converters provide high galvanic isolation, extreme spike immunity, and long-term durability engineered under strict German ISO 9001 manufacturing standards.

  • Direct connection to high-voltage DC bus lines (450VDC to 820VDC operating range)
  • 1 to 3 isolated DC inputs for redundant power paths or multi-string sources
  • Ultra-low ripple and noise performance for precise PLC and sensor operation
  • High electrical efficiency with robust thermal management up to +60°C without derating

Engineering Superiority

Why International System Integrators Choose CAMTEC DC/DC Converters

Built to operate reliably under extreme grid fluctuations, high thermal loads, and harsh industrial environments.

High Surge & Transient Protection

Internal protection circuits shield connected sensitive electronics from high voltage transients, back-EMF spikes, and rapid voltage swings typical of DC mini-grids.

Optimized Energy Efficiency

By stepping down directly from high-voltage DC lines without intermediate AC inversion steps, overall energy losses are reduced by up to 15–22% across factory systems.

Galvanic Isolation & Safety

Completely isolated design prevents ground loops and ensures full operational safety compliant with stringent international low-voltage and isolation directives.

Target Applications

Where High-Voltage DC/DC Converters Deliver Maximum Value

Modern industrial installations are increasingly relying on localized direct-current infrastructure to streamline power management, harvest renewable energy, and ensure continuous operation during grid instability.
