Power quality, metering and power supplies from ABB, Siemens and Schneider Electric: over 700 products for measuring energy, supplying control circuits and correcting power factor in low-voltage panels. The range covers rated currents from under 1 A to 6000 A and DC supplies up to 98.5 kW. Stoklink ships worldwide from Turkey and quotes project volumes on request.

What's in this range

  • Energy Meters & Power Analyzers – multifunction meters, energy analyzers and wireless energy sensors for monitoring load and consumption.
  • Current Transformers – primary-to-5 A and low-voltage output transformers that feed meters, relays and analyzers.
  • Power Supplies – 24 V DC DIN rail units, DC UPS and buffer modules, redundancy and selectivity modules.
  • Power Factor Correction – capacitors and related components that reduce reactive power in the installation.

How to choose

  • Define the job first: billing-grade energy metering, power quality analysis, control power or reactive compensation each need a different product family.
  • Match ratings to the circuit. Meters and transformers follow the primary current and system voltage, supplies follow the load current at 24 V DC, capacitors follow kvar and network voltage.
  • Check accuracy class for metering points. Class 0.2S, 0.5 and 1 are common choices depending on whether the data is used for billing or for monitoring.
  • Confirm mounting and communication: DIN rail or panel cut-out, Modbus or Ethernet interfaces, and input voltage range of the supply.

FAQ

What is the difference between an energy meter and a power analyzer?

An energy meter mainly records kWh consumption. A power analyzer also measures harmonics, power factor, demand and waveform data, so it suits power quality studies.

Do I need current transformers with every meter?

Not always. Direct-connect meters take current up to their rating. Above that, a meter normally works with current transformers, typically with a 5 A secondary.

Do you ship these products outside Turkey?

Yes. Stoklink ships worldwide from Turkey under EXW terms. Lead time depends on distributor stock, and bulk quotes are available on request.
