DEIF PSM-1 Power Supply Module – Stable DC Backbone for DEIF Controller Systems

The DEIF PSM-1 is a compact power supply module designed to deliver stable low-voltage DC to DEIF control systems in generator sets, switchboards, and marine power management panels. From my experience, the PSM-1 is typically used as the dedicated supply backbone for DEIF controllers and I/O modules, keeping the system up even during voltage dips and noisy environments.

Notes: The PSM-1 is used across several DEIF controller setups; minor variations can exist by hardware revision. If you’re matching an existing panel, share the controller type and photo of the installed unit for a precise check.

Application Fields

• Generator sets and AMF/ATS panels – steady 24 V DC to AGC/ASC controllers and I/O during cranking and load transfer.
• Marine & offshore power management – supplies DEIF controllers in bridge and engine room switchboards.
• Industrial switchgear & CHP – continuous DC supply for monitoring, protection, and load-sharing modules.
• Microgrids & hybrid systems – reliable DC rail for mixed sources (diesel, PV, battery) with frequent transients.

Advantages & Value

• Reliability under transients – In many cases, swapping to a clean, module-level supply reduces random controller resets.
• Native fit with DEIF – Wiring and mounting are straightforward, which keeps installation hours down.
• Service-friendly – You might notice the terminals and indicators are laid out for quick checks during commissioning.
• Lower lifecycle cost – Stable power extends controller life and cuts downtime; spares stocking is simple.
• Technical support – We typically verify compatibility by controller type and cabinet photos before shipping.

Installation & Maintenance

• Cabinet & environment – Install in a ventilated, dry enclosure (IP20 or better inside cabinet). Keep ambient within the stated temperature range and allow airflow around heat-dissipating surfaces.
• Wiring – Use properly sized conductors for DC output and protective earth. Keep DC lines separated from high-noise cables (contactors, VFD output). Tighten terminals to the recommended torque.
• Protection – Fit upstream fusing or a DC breaker according to the expected load current. Ensure correct polarity to avoid nuisance trips.
• Commissioning – Verify output voltage under load. Check status LEDs and, if present, confirm “power OK” relay state.
• Routine maintenance – Every 6–12 months, inspect terminals for looseness, clean dust to maintain cooling, and log output voltage. Firmware is not typically user-updated on power-only modules.
• Safety – De-energize before servicing. Follow local electrical codes and panel builder standards.

Quality & Certifications

• CE marked; designed for industrial EMC environments
• RoHS compliant materials
• Manufactured under ISO 9001 quality systems (manufacturer)
• Warranty: 365 days replacement/repair coverage

Practical Notes from the Field

A service engineer at a marine yard told me they swapped a PSM-1 into a DEIF-based AMF panel in under 10 minutes—no rewire, just verify polarity and tighten terminals. Since then, their nuisance resets during engine cranking seem to have disappeared.

Related Components (for planning)

• DEIF AGC/ASC controllers – main control targets powered by PSM-1
• DEIF I/O modules (e.g., IOM series) – ensure sufficient DC capacity for added I/O
• DIN-rail surge protection – recommended on DC lines in high-noise sites
