Description

APK120 Series – 120W High Reliability Industrial Isolated DC-DC Converters (Selectable Input and Output)

The APK120 series is a family of high reliability 120W isolated DC-DC converters designed for demanding industrial, transport, and automation environments. Available with nominal 12Vdc, 24Vdc, or 48Vdc input options, each model provides regulated outputs of 12Vdc, 24Vdc, or 48Vdc, with an adjustable range (±7%) to fine-tune system requirements.

Engineered for industrial-grade performance and long-term reliability, the APK120 series features conversion efficiency up to 92%, reinforced isolation (2250Vdc), and full protection against short circuit, overvoltage, overload, and thermal faults. Its rugged construction and wide input ranges make it ideal for integration into high reliability power systems, control panels, battery-powered devices, transport electronics, and telecommunications equipment where uptime is critical.

Compact and versatile, APK120 converters support both DIN rail and panel mounting, making them suitable for a wide range of installations.

Features and Benefits

  • 120W high reliability isolated DC-DC converters
  • Designed for industrial and transport environments
  • Nominal input options: 12Vdc, 24Vdc, 48Vdc
  • Nominal output options: 12Vdc, 24Vdc, 48Vdc (adjustable ±7%)
