Meter type transformer products mainly include ZMCTCB series, ZMDCT series, ZMCD series, ZM-N3 series, etc.

Application Characteristics

ZMCTCB series: Mainly used for national grid metering projects, the product has small size and the function of DC resistance, and can be hard-connected, which is convenient for the automatic production of meter products. The sampling resistance of the product is small (generally less than or equal to 20Ω), the linearity is better than 0.2%, and typical transformation ratio is 5(60)A/2.5mA 5(80)A/2.5m.

ZMDCT series: Mainly used for meter products (national grid meter, overseas meter), the product has small size and the function of DC resistance, and can be hard-connected, which is convenient for the automatic production of meter products. The sampling resistance of the product is small (generally less than or equal to 20Ω), the linearity is better than 0.1%, and typical transformation ratio is 5(60)A/2mA 5(80)A/2mA 5(60)A/2mA 5(100)A/2mA.

ZMCD, ZM-N3 series: Copper bar is used as the primary input terminal, and the product is small, which is convenient for customers to connect the transformer and the input terminal of the meter. The product is mainly used for small current testing (1.5A current detection). The sampling resistance of the product is small (generally less than or equal to 20Ω), the linearity is better than 0.1%, and typical transformation ratio is 1.5(6)A/5mA.
