Compact measurement devices optimized for low-voltage switchboards, local EV charging infrastructures, and modular sub-metering setups.
The Lisbon metropolitan area is undergoing a profound energy infrastructure revitalization. Propelled by Portugal's National Energy and Climate Plan (PNEC 2030) and municipal clean energy mandates, commercial buildings, industrial zones, and local microgrids are standardizing their telemetry systems.
As the city integrates more distributed solar photovoltaic (PV) installations and expands its EV charging network (MOBI.E), the demand for high-reliability, space-saving measurement devices has escalated. DIN Rail mounted current transformers (CTs) serve as the hardware foundation of these setups. They translate high-amperage lines into safe, measurable secondary currents (e.g., 5A or 1A) for energy meters, power quality monitors, and RTUs in distribution sub-panels.
A globally recognized pioneer in electromagnetic measurement and electrical safety technologies since 1993.
Every single current transformer undergoes rigorous fabrication, insulation coating, core loading, and automated testing to comply with international standards.
Solving accuracy, space, and deployment constraints for electrical contractors and panel builders globally.
Our DIN rail CTs deliver extremely linear current signals to telemetry hardware. By ensuring minimal phase displacement and ratio error, RTUs can communicate accurate operational parameters to central SCADA engines used by Portuguese distribution operators like E-Redes.
Utilizing high-grade silicon steel and advanced toroidal winding configurations, we suppress core saturation during transient overcurrent events. This provides clean harmonics representation for power quality analyzers monitoring commercial machinery loads.
Our products comply with standard IEC 61869-2 (replaces former IEC 60044-1). We support electrical testing processes conforming to European CE, RoHS, and REACH guidelines, guaranteeing safety across commercial real estate, data centers, and multi-tenant offices.
As power distribution evolves toward dynamic, bidirectional flows due to wind, battery storage, and localized microgeneration, current sensing technology must adapt.
Zentar® is actively developing low-power current transformers (LPCT) based on resistive shunts and advanced Rogowski coil sensors. These technologies deliver linear outputs across wide dynamic current margins without saturation limits. They feature negligible phase shift, allowing modern sub-meters to track phase angles under complex reactive loads.
Furthermore, our integrated smart models include IoT communication protocols directly inside DIN Rail enclosures, minimizing physical assembly space. This allows system integrators in Lisbon to deploy multi-channel submetering setups directly within space-constrained distribution boards.
From low-voltage miniature DIN Rail designs to robust outdoor medium-voltage epoxy resin systems, we supply diverse applications worldwide.
