Designed to withstand severe lightning transients, grid switching impulses, and industrial overvoltages. Fully customizable with private labeling, specialized EN 61643-11 compliance ratings, and bespoke footprint configurations for local panel integration.
Ireland’s industrial electrical landscape presents unique operational parameters for power electronics and electrical protection equipment. Operating on a 230V / 400V 50Hz supply network under National Rules for Electrical Installations (I.S. 10101:2020 / ET101), electrical panel builders, OEM equipment manufacturers, and facility engineers face distinct power quality phenomena. The rapid integration of high-density renewable energy—particularly offshore wind farms along the Atlantic Margin and utility-scale solar PV in Munster and Leinster—has significantly altered system impedance and transient profile behaviors across the EirGrid transmission network.
To ensure operational resilience against severe impulse events, switching surges, and lightning-induced transients, selecting the appropriate Surge Protective Device (SPD) topology and transient voltage suppression (TVS) incorporated SMPS units is critical. As an established OEM/ODM manufacturing partner, Sanstar Microsystems (Micro Power) provides customized surge protection solutions designed precisely around European and Irish standards (I.S. EN 61643-11 and IEC 61643-31).
When specifying custom OEM surge protection modules or power supplies with built-in surge suppression for installation in Ireland, electrical engineers must evaluate three primary protective tiers:
| Class & Type | Impulse Current Waveform | Typical Application in Ireland | Core Technology Topology | Key Performance Standard |
|---|---|---|---|---|
| 10/350 µs ($I_{imp} \ge 12.5\text{kA}$) | Main Service Entrance, Exposed Structures, Wind Turbine Base Panels | Spark Gap / Encapsulated Heavy GDT + High Joules MOV | I.S. EN 61643-11 Class I | |
| 8/20 µs ($I_{n} \ge 20\text{kA}$, $I_{max} \ge 40\text{kA}$) | Sub-distribution Boards, Industrial Machinery, Data Center PDU Racks | High-Capacity Metal Oxide Varistors (MOV) with Thermal Disconnect | I.S. EN 61643-11 Class II | |
| 1.2/50 µs - 8/20 µs ($U_{oc} \le 10\text{kV}$) | Sensitive Terminal Devices, PLC Inputs, CCTV Cameras, Medical Electronics | Hybrid TVS Diodes + Fast-Response MOVs + LC Filtering Circuits | I.S. EN 61643-11 Class III |
In Irish earthing topologies—specifically TN-C-S (Protective Multiple Earthing / PME) and rural TT earthing systems—the potential for neutral-to-earth potential rise during ground fault conditions requires specialized internal wiring configurations. Our custom OEM factories produce "3+1" and "4+0" protection circuits utilizing high-energy Gas Discharge Tubes (GDT) between the neutral and protective earth (PE) conductors. This architecture prevents leakage currents to earth during nominal operations while guaranteeing zero-follow-current suppression during severe transient discharges.
From Dublin's hyperscale digital infrastructure to off-grid marine installations in Galway, our custom surge protection designs serve mission-critical applications across the island.
Ireland, particularly the greater Dublin region (Clondalkin, Tallaght, Grange Castle), hosts one of Europe's dense concentrations of enterprise and hyperscale data centers. Power quality and continuous uptime are non-negotiable requirements.
OEM Solution Integration: We manufacture low voltage protection level ($U_p < 1.0\text{kV}$) Type 2 and Type 3 surge suppressed DIN rail power supplies for server rack monitoring, BMS (Building Management Systems), and static transfer switches. Featuring fast response times ($<25\text{ns}$) and remote status indication contacts, our units seamlessly connect with centralized SCADA systems to alert facility managers before surge degradation causes downtime.
With Ireland targeting 80% renewable electricity by 2030, offshore wind turbines along the West Coast and coastal solar arrays face intense atmospheric exposure, harsh salt mist, and frequent lightning strikes.
OEM Solution Integration: Our factory supplies ruggedized, C5-M anti-corrosion coated Type 1+2 combined surge arrestors and heavy-duty switching power converters. Built with sealed IP67 enclosures and conformal coated PCBs, these devices tolerate extreme thermal shock (-40°C to +85°C) and dissipate high-energy direct lightning currents ($I_{imp}$ up to 25kA 10/350µs per pole) without thermal runaway.
Galway is a premier global hub for biomedical device engineering. Manufacturing plants operate cleanroom environments where micro-transients from heavy inductive motor switching can compromise automated testing tools and silicon wafer assembly lines.
OEM Solution Integration: We deliver custom multi-stage EMI/RFI filtered surge suppression modules adhering to EN 61000-4-5 high-immunity criteria. These custom power modules ensure ultra-low residual output ripple ($<30\text{mV}_{p-p}$) and suppress sub-microsecond voltage spikes, safeguarding sensitive PLC controllers, automated vision systems, and robotic assembly arms.
Ireland’s agricultural heartland relies heavily on automated dairy infrastructure, processing plants, and municipal pumping stations operating at the ends of long rural overhead utility lines prone to voltage sags and lightning surges.
OEM Solution Integration: Sanstar Microsystems provides robust DIN-rail surge protectors engineered with wide input operational windows (90VAC - 300VAC continuous) and integrated self-monitoring thermal disconnect fuses. These units survive high Temporary Overvoltage (TOV) conditions caused by rural transformer switching and phase-neutral unbalances typical of long feed lines.
The Irish power electronics sector is experiencing a paradigm shift driven by legislative directives, sustainability commitments, and rapid industrial electrification. OEM buyers and panel builders across Cork, Dublin, Limerick, and Belfast are aligning their component procurement with several key trends:
Following updates in national wiring standard I.S. 10101:2020, mandatory surge protection risk assessment rules have tightened across Ireland. Facilities housing high-value machinery, IT equipment, or public infrastructure must fit Type 1 and Type 2 surge suppression at incoming distribution boards. OEM factory builders are moving away from discrete MOV component assembly toward pluggable, pre-certified modular SPD assemblies that cut assembly labor costs and ensure simple field replacement during maintenance.
As remote monitoring becomes standard in smart factories and unmanned renewable sites across Ireland, traditional visual status flags (green/red indicators) are no longer sufficient. Modern Irish procurement requests target smart surge protective devices with potential-free dry contacts (auxiliary switch outputs) or embedded RS485/Modbus telemetry. Our engineering team provides custom OEM circuit boards that transmit real-time varistor degradation data, surge event counters, and thermal overload alerts directly to central SCADA networks.
Space optimization inside industrial control panels is a top priority for European equipment manufacturers. By using high-density components and advanced thermal dissipation substrates, our factory manufactures ultra-slim surge-protected power supplies (down to 30mm width formats). Additionally, our manufacturing processes comply strictly with EU RoHS 3 (Directive 2015/863) and REACH regulations, ensuring full environmental alignment for Irish companies exporting finished machinery across the EU single market.
