The input voltage source of 220 V and 50 Hz frequency was connected to variac
device, of 8 Amperes and output voltage range from 0 to 250 V, in order to control the output (A.
Una vez ajustado el Variac
para un flujo cercano al deseado, se iniciaba el desplazamiento del aire en un momento dado, siguiendo visualmente los valores del contenido de aire en el espirometro y cuando el o los medidores de presion asociados indicaban un regimen estable, se media el tiempo asociado con el paso de 30 litros de aire.
Controlled by a Variac
, a high voltage was gradually applied to the electrode and monitored on the digital display of the digital multimeter.
Illumination was adjusted by means of a variac
to the minimum level necessary to provide good contrast between the squid and the background.
I work with a thing called a variac
, a transformer which alters input from a power supply.
If your tolerances are very loose--say |+ or -~ 10%--you can get away with almost anything, even a jury-rig consisting of a Variac
, a rectifier, and a filter capacitor.
To reduce power to the lower level required in experiments at the University of Maryland and the Baystate Medical Center, a variac
is used to lower input voltage.
Is a 44 year old manufacturer of Uninterruptible Power Supplies, Power Line Conditioners, custom linear and switch mode power supplies, Variac
auto transformers and voltage regulators and invertors.
Tenders Are Invited For Supply of Single Phase Variac
, 0-250V / 3 Phase Variac
, 0-500V, 15A
The Performance analysis of dc-dc converter with variac
has keep wide output voltage in low input voltage conditions.
Temperature should be PID controlled--no variac
system: A variable transformer (model number 3PN1010b-DVM) was used to maintain a voltage of 120 V to the fan supplying combustion air to the burner.
