Stable 24 V DC output – Provides regulated DC power for DEIF controllers and expansion modules, helping prevent nuisance resets during cranking or load steps.
Industrial noise immunity – Designed for harsh electrical environments commonly found in genset and marine panels; you might notice fewer spurious alarms after upgrading.
Compact footprint – Fits neatly in crowded cabinets; typically DIN-rail friendly to simplify retrofits and spares management.
Status indication – Front LEDs indicate module health and output status, making troubleshooting faster on-site.
Protective features – Overload and short-circuit protection are commonly built in to protect downstream devices.
Native ecosystem compatibility – Pairs cleanly with DEIF AGC/ASC families and auxiliary I/O modules, reducing wiring complexity.
| Brand / Model | DEIF PSM-1 Power Supply Module |
| HS Code | 8504.40 (Static converters / power supplies) |
| Power Requirements | 24 V DC nominal (typical operating window 18–32 V DC); designed to feed DEIF control electronics |
| Dimensions & Weight | Compact module for panel/cabinet integration; approx. single-width DIN-rail footprint |
| Operating Temperature | -20 to +70 °C (typical industrial range) |
| Signal I/O Types | DC power output to system bus; front LED indicators; optional relay contact for power OK (varies by configuration) |
| Communication Interfaces | None (power-only module; supervision via status indication/relay if present) |
| Installation Method | DIN-rail EN 60715 or panel integration alongside DEIF controllers; pluggable terminals for quick service |
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.
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.
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.
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.
CE marked; designed for industrial EMC environments
RoHS compliant materials
Manufactured under ISO 9001 quality systems (manufacturer)
Warranty: 365 days replacement/repair coverage
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
