Thông tin sản phẩm
  • UPA-16 is a mobile device, which could be easily transported to a required testing location.

    UPA-16 operates on the principle of varying the power in the primary circuit of the matching power transformer and, respectively, varying the output current, flowing through the automatic circuit breaker under the test. Power regulation could be done either through an external regulator (RNO or VR) or through a built-in thyristor controller.
