BACHMANN NT255 – Industrial 24VDC Power Supply Module | BACHMANN MPC / CPC Series
Engineering Background: The BACHMANN NT255 is a dedicated DIN rail-mount power supply module engineered for BACHMANN’s MPC and CPC programmable automation controller (PAC) platforms. Designed to deliver stable, regulated 24VDC output to controller backplanes and I/O modules, the NT255 is a critical infrastructure component in high-availability industrial control architectures across energy, wind turbine, marine, and process automation sectors.
Product Positioning: As a genuine OEM replacement and new-surplus unit, the NT255 is the preferred sourcing choice for maintenance engineers seeking drop-in compatibility without re-engineering. Konmask.com stocks verified units with full traceability, supporting both planned upgrades and emergency MRO procurement.

System Architecture & Signal Flow
The NT255 mounts directly into the BACHMANN MPC or CPC controller rack via the backplane bus connector. AC mains input (typically 100–240 VAC, 50/60 Hz) is converted and regulated to 24 VDC, which is distributed across the backplane to power the CPU module, communication modules, and I/O expansion modules. The module’s status LED provides real-time power-good indication. In redundant configurations, dual NT255 units can be deployed in parallel racks for N+1 power availability.

Technical FAQ
Q: Is the NT255 compatible with both MPC and CPC BACHMANN racks?
A: Yes. The NT255 is designed for the BACHMANN backplane bus standard used across MPC and CPC series racks. Always verify your rack’s power slot specification against the NT255 datasheet before installation.
Q: What is the input voltage range of the NT255?
A: The NT255 accepts wide-range AC input (typically 100–240 VAC, 50/60 Hz). Confirm with the official BACHMANN NT255 datasheet for your specific hardware revision.
Q: Can I use the NT255 in a redundant power configuration?
A: Yes. BACHMANN MPC racks support dual power supply slots. Two NT255 units can be installed for N+1 redundancy, ensuring uninterrupted controller operation during a single PSU failure.
Q: Do you provide a warranty?
A: All units sold by Konmask.com carry a 90-day functional warranty. Extended warranty and service agreements are available for volume procurement — contact support@konmask.com.
Q: How quickly can you ship?
A: In-stock units ship within 1–2 business days. Express delivery to most destinations in 3–7 business days via DHL or FedEx.
