¶ LPVT Amplifier
The VECTO LPVT Amplifier is a high-performance, 100kHz bandwidth device specifically designed to convert the output signals of Low-Power Voltage Transformers (LPVTs) into conventional 110VL-L output signals. This innovative solution addresses the limitations of traditional Voltage Transformers (VTs), which often lack the bandwidth and accuracy required for effective harmonic measurement.
LPVTs offer superior bandwidth and phase performance compared to traditional VTs but frequently present output voltage levels incompatible with standard measurement equipment. The VECTO LPVT Amplifier bridges this gap by enhancing LPVT output signals to match the levels of conventional VTs (±63.5VL-E), ensuring seamless compatibility with existing systems.
A LPVT and VECTO LPVT Amplifier combination serves as a cost-effective, high-performance alternative to traditional VTs. Offering an impressive 100kHz bandwidth, far superior to the typical ±2kHz bandwidth of traditional VTs
¶ Important Notes
-
A load resistor may be required for the LPVT depending on the model. Ensure that the LPVT is compatible with high-impedance inputs; if not, the use of a load resistor may be necessary to maintain optimal functionality.
-
Gain must be specified at purchase. Gain values can range from 10 to 100.
