Product Description

The NT250 is a specialized DC power conversion module for the Bachmann M1 automation system, providing stable, filtered, and isolated voltages to the backplane and connected modules. Engineered for industrial and telecommunications environments, it supports a wide input range (38–58 VDC) and delivers three independent output voltages for logic, analog, and interface circuits. Passive cooling and high galvanic isolation ensure reliable operation in distributed automation systems with minimal maintenance.

Technical Specifications

Specification Details
Model Identification NT250
Input Voltage Range 38 – 58 VDC Nominal
Peak Input Tolerance +60 V (<1 s/min transient)
Inrush Current Limit Max. 7 A (<0.5 s)
Total Output Power 42 W
Galvanic Isolation 500 V (Input → Bus), 100 V (Input → Ground)
Thermal Management Passive convection cooling
Operating Temperature 0°C to +60°C

System Reliability & Safety

  • High Isolation: Protects CPUs and sensitive I/O from electrical transients and ground loops.

  • Inrush Limiting: Prevents upstream fuse trips during startup, critical for multi-module M1 racks.

  • Precision Analog Support: Dual ±15V rails maintain accurate analog module performance.

Hardware Role & Comparison

  • Optimized for 48V Systems: Ideal for telecom-grade or battery-backed automation setups.

  • High Output Capacity: +5V rail supports high-power processor modules and multiple communication interfaces.

  • Dual-Rail Analog Support: Unlike entry-level 24V modules (e.g., NT255), NT250 supplies ±15V for precision analog I/O.

Frequently Asked Questions

Q: Can the NT250 operate in 24V DC systems?
A: No. It requires minimum 38 VDC input. For standard 24V systems, use the NT255 or equivalent.

Q: Does the module provide status diagnostics?
A: Yes. Front-facing LED indicators display the presence and stability of output voltages for quick visual verification.
