Error %E p a g e | 14 4 ZETTLER Magnetics – Current Sense Transformers ACST-265-10 These AC-Current-Sense-Transformers (ACST) are used in control and monitoring applications, at protective circuits or load detection systems with purpose to confirm that the designated current actually flows, or whether the current differs significantly due to an overload, construction damage, or other failure. The main applications are in 50 Hz- or 60 Hz-systems. Figure 18: ACST-265-10 The primary winding is integrated in the sensor; this saves assembling time and results in a clear defined compact component with outside dimensions of just 20.0 x 17.8 x 23.8 mm. The measurement signal is isolated from the primary AC side, thus the sensor can be implemented at any point within the electrical circuit. The magnitude of the sensor’s output voltage may be adapted to the specific application by selecting an appropriate R L value. For the ACST-265-10 and a load resistor of up to 60 Ω it is linear in the whole measurement range up to 36 A rms . Burden resistor RL and meter not included and shown for reference only.
