The 7443 series totalizers are perfect for a wide range of industrial applications. Precision internal working parts are supported and protected by its die‑cast frame and heavy‑duty enclosure. Available with popular AC and DC voltage ranges, mounting styles, and reset features. Series 7443 is a good choice for new applications requiring an industrial duty counter, or for updating existing installations. Applications with poorly conditioned AC power lines are no problem. Rectifiers, which frequently fail due to power surges and transients, are not used. Instead, a precision wound coil drives AC models of series 7443.
