Caractéristiques
Description
- Type / Model: EF 34 TP 127
- Primary Side (Input / PRI): 220 V at 2 A, operating on standard alternating current grid frequency of 50 - 60 Hz.
- Secondary Side (Output / SEC): It features two separate output windings (SEC 1 and SEC 2), each delivering 24 V at a current of 8.33 A.
- Protection / Fuse Requirements: It specifies using a 2.5 A/T slow-blow fuse (T stands for time-delay or traag) that complies with the IEC 127 standard to protect the circuit from short-circuits and overcurrent.
Standards & Safety:
- IEC 742: The international standard governing safety isolating transformers.
- Double Square Symbol: Indicates Class II insulation (double insulated), meaning the device does not strictly rely on a safety earth connection for shock protection.
- ta 40/E: Ambient temperature limit (\(t_{a}\)) is 40°C, and the insulation system utilizes Class E thermal materials.
How it is configured:
Because it has two identical 24V secondary loops, they can typically be wired in two configurations depending on the application.
- Parallel: Combining the currents to get 24V output with a maximum capacity of 16.66A.
- Series: Combining the voltages to get a single 48V output with a maximum capacity of 8.33A.
