Description
The UNI-T UT25 Series (UT25A / UT25B) is an industrial-grade diagnostic instrument engineered for rapid identification of branch circuit protective devices (breakers and fuses) without interrupting power to connected loads. Comprising a dedicated signal transmitter and a high-sensitivity electromagnetic receiver, the system utilizes encoded frequency signal injection into live AC electrical networks. Designed with Original Engineering standards, the unit eliminates guesswork during facility panel mapping, compliance audits, and preventive maintenance routines.
INDUSTRIAL APPLICATION SCENARIO
In high-availability industrial manufacturing facilities and commercial data centers, de-energizing power distribution units (PDUs) or sub-panels to locate target circuits risks costly unplanned downtime and disruptions to critical automation networks. The UT25 system operates under live conditions, enabling maintenance personnel to plug the transmitter into a field receptacle and sweep the receiver wand across multi-tier breaker panels. The dynamic sensitivity control isolates the strongest localized electromagnetic emission, identifying the exact branch breaker feeding the endpoint with high precision.
