VARIABLE TRANSFORMER 1000VA 4A
This is a new variable transformer with 220V AC, 50Hz single phase, and the output voltage can be adjusted from 0 to 300V. The maximum power rating is 1000VA.
The transformer transformer has a clear voltage output meter and a precision metal pressure meter. It has high design precision, compact structure and easy transportation.
Reliable and perfect current limiting protection, thermal protection, voltage overload protection and short circuit protection. Device grounding port provides more stable and safe protection
Nominal Current:
To allow maximum utilization of Variacs, the output ratios are given for constant current and constant load impedance.
Excellent Regulation
Variacs deliver the output voltage with negligible variation between the no-load state and the full-load state.
High efficiency
The wattage losses of each Variac are very low in contrast to the inefficient control provided by rheostats and other resistive-type drivers.
Waveform distortion
A Variac provides an output voltage that is a faithful, distortion-free reproduction of the input signal waveform. This is a necessary feature of many electronic applications and is the result of excellent design and the use of high quality grain oriented silicon steel.
Widely used in motor speed control, label printing machine, laboratory, railway interchange test, power supply, satellite, equipment, telecommunications equipment, etc.
This variable transformer is designed with a built-in copper coil suitable for long-term use. With an LCD display, flexible rotating wheel and safety protection, the compact voltage transformer is of high quality and can provide more stable and safe supply.
