Ultramicro voltage transformer-TR3121
Sophisticated current type voltage transformer. The primary is stringed into the resistor through the circuit, the resistance is converted into current , after the current converting by the transformer, the secondary output current signal is converted into the needed voltage by sample resistor. Pin output, used for measuring. |

Usage |
During use, resistors must be arranged in series in the primary circuit, with voltage converted to current. Adjusting the feedback resistor, the needed voltage output is obtained through the operational amplifier. Output. In order to ensure a excellent linearity, the resistance value should not be very high, generally less than 200Ω. This product also can be specially customed. |
