CT102 Current Transformer – Through-Hole Micro Current Sensor for Energy Meters & Power Monitoring

The CT102 current transformer is a compact through-hole (donut/toroidal) micro current sensor engineered for accurate AC current sampling in smart energy meters, EV charging equipment, solar inverters, UPS systems and industrial power monitoring devices. With an epoxy-encapsulated housing, twisted lead wires and a plug-in connector, the CT102 delivers high linearity, low phase error and long-term stability in a footprint small enough for tight PCB and DIN-rail layouts. Full OEM & ODM customization is available on turns ratio, output, wire length and connector type.

Key Advantages
  • High efficiency & high accuracy – stable turns ratio with low ratio error, suitable for Class 1 / Class 0.5 metering designs.
  • Low noise & low temperature rise – optimized magnetic core and winding process minimize audible noise and self-heating.
  • Stable performance – consistent output over a wide operating temperature range, ideal for outdoor meters and cabinets.
  • Durable & reliable – flame-retardant epoxy encapsulation, moisture-proof and vibration resistant.
  • 5-year warranty; up to 20-year warranty for special industries (rail, energy, metering infrastructure).
  • OEM & ODM – custom ratio, output signal, lead length, terminal/connector and labeling.

FAQ
Q1: What is a CT102 current transformer used for?
It converts a large AC primary current into a small, proportional secondary signal so that meters, MCUs and protection circuits can measure current safely and accurately.
Q2: Can the turns ratio and output be customized?
Yes. Send us your rated primary current, required ratio, burden resistor and accuracy class, and we will design the matching version.
Q3: What is the minimum order quantity?
MOQ is 100 pcs. Samples are available for evaluation before mass production.
Q4: How long does mass production take?
Quotation within 3 days, samples within 7 days; mass-production lead time is confirmed with the order according to quantity.
Q5: Do you accept OEM / ODM projects?
Yes. We support drawing-based ODM, private labeling and customized wire length, connector type and packaging.
Q6: How is quality controlled?
Incoming material inspection, in-process control and 100% electrical testing (ratio, phase error, hi-pot) before packing.
