From thin-form industrial DIN rail modules to ruggedized high-power units, our ISO 9001-certified manufacturing facility delivers compliant, high-MTBF power supplies calibrated for severe Nordic electrical control cabinets.
The industrial switchgear and automation landscape across Finland—from the maritime logistics hubs of Turku and Helsinki to the forestry and pulp manufacturing operations in Central and Northern Finland—demands an uncompromising balance of dimensional compactness, electrical ruggedness, and commercial feasibility. The EDR DIN Rail Power Supply Series (EDR-75, EDR-120, EDR-150, EDR-240, and EDR-480) is engineered as a modern, high-density solution mounted directly on standard TS-35/7.5 or TS-35/15 DIN rails. Unlike legacy encapsulated transformers that waste energy through significant thermal dissipation, our EDR series incorporates advanced primary resonant topology and synchronous rectification, achieving continuous operational efficiency ratings up to 92%.
Cabinet real estate in European standard IP66 and Rittal junction boxes is at a premium. The EDR family features an optimized narrow width (as slim as 32mm for 75W and 40mm for 120W models), allowing systems integrators to cluster more I/O modules, safety relays, and Ethernet switches onto a single TS-35 rack.
Unheated outdoor terminal cabinets in Finland undergo severe sub-zero thermal cycling during Arctic winters. The EDR units incorporate low-ESR solid electrolytic capacitors rated for -40°C start-up, eliminating inrush damage, voltage drops, or soft-start lockouts under freezing ambient circumstances.
Equipped with passive or active Power Factor Correction (PFC), the EDR platform complies rigorously with SFS-EN 61000-3-2 Class A harmonic limitations, preventing common-mode and differential-mode noise injection across sensitive Nordic SCADA networks and field sensors.

Finland possesses one of the world's most sophisticated and highly automated manufacturing, clean energy, and process industry landscapes. Generic commercial power supplies routinely fail when exposed to the thermal differentials, ambient moisture, and continuous duty cycles required by Finnish system integrators.
Finland’s forestry clusters (centered around Kymi, Äänekoski, and Oulu) run continuous-process papermaking, pulping, and timber milling machinery. The operational environment combines elevated atmospheric humidity, airborne wood particulate, and extensive industrial drive vibration.
Our EDR series features heavy-gauge galvannealed steel housings with conformal coating options that isolate internal PCB components from hygroscopic dust and mild chemical sulfates. The solid TS-35 DIN rail snap-in mechanism has been vibration tested to 2G (10–500Hz, 10 min/1 cycle, 60 min each along X, Y, Z axes according to IEC 60068-2-6), ensuring uninterruptible 24VDC DC-bus stability for PLCs and distributed sensor networks.
Finland’s Vaasa energy cluster and Turku shipyards represent the gold standard in global marine power management, hybrid electric vessel propulsion, and port electrifications. Control units in marine auxiliary switchgear must tolerate transient voltage spikes and severe electromagnetic disturbances caused by heavy thrusters and variable frequency drives (VFDs).
The EDR DIN rail supplies deployed in auxiliary shipboard cabinets provide 3000VAC input-to-output hi-pot galvanic isolation, 100% full-load burn-in screening, and compliance with the heavy industrial immunity standard EN 61000-6-2. Our units deliver ripple and noise values below 100mVp-p, protecting mission-critical marine telemetry and fuel-injection controllers from erratic data transmission.
With the rapid growth of wind farms across Ostrobothnia and Lapland, grid-scale Battery Energy Storage Systems (BESS) and substation secondary distribution switchgear require auxiliary DC power supplies capable of operating reliably in unheated outdoor containerized substations.
The EDR platform provides wide-range universal AC input (90–264VAC) with DC input compatibility (127–370VDC), allowing direct connection to station auxiliary battery banks during grid dropouts. Its over-voltage, over-load (constant current limiting mode), and thermal protection circuits prevent catastrophic shutdowns during lightning surge events on long rural distribution feeds.
Finland’s aggressive national goal of carbon neutrality by 2035 is driving a widespread electrification wave across building automation, industrial heating (high-capacity industrial heat pumps), and smart district energy grids. System builders and panel manufacturers (sähkökeskusvalmistajat) are facing stricter procurement specifications regarding conversion efficiency, lifecycle carbon footprint, and international traceability.
In adherence to EU Ecodesign directives and Finnish building energy efficiency decrees (Ympäristöministeriön asetus uuden rakennuksen energiatehokkuudesta), our EDR series ensures no-load power consumption below 0.3W–0.75W, significantly reducing parasite loads across large distributed automation projects.
All EDR power supplies manufactured for export to Finland comply with SFS-EN 62368-1 audio/video, information, and communication technology standards, replacing obsolescent EN 60950-1 and EN 60065 certifications.
