Sanxin SVC-3000VA Fully Automatic
Voltage Regulator. (Inv #8206) Servo-motor
driven
variable transformer type AC voltage regulator great for computers,
printers, laboratory equipment and other equipment that requires
steady input voltage. Input: 70-130VAC, Output: 110V +/- 2%, Input:
170-240VAC, Output: 220V +/- 2%. Relative Humidity: < 95%.
Over-current Protector: circuit breaker. Size: 9" X 9"
X 13", Shipping Wt. ~38 lbs. Very good used condition, checked,
guaranteed. Price: $99.00
Technipower Type W20G3M, Variac,
3-Gang, Cased. (Inv #7772, 7804) Input: 3 X
120VAC,
Output: 3 X 140VAC, 3 X 20A. This versatile unit can simultaneously
control three 120V, 20A circuits or can be used to control a single
three-phase circuit. (Can be used as a Wye-connected device to
control 240V 3-phase circuits. This is possible because the voltage
from line to neutral of a wye-connected assembly is the line voltage
divided by the square root of 3; thus, in the case of a 240 volt,
3-phase line, the voltage across each coil would be 138 volts.
Since 120-volt Variac units are wound for 140 volts across the
whole winding, three 120-volt Variac units can be wye-connected
if the over-voltage connection is omitted. The load rating of
a wye-connected assembly is 3.47 times that of a single unit,
or in this case, 69 Amps.) This model is a continuation of the
original General Radio Variac series, and is a current model from
Technipower, LLC. Weight: approx. 71#. Good used condition, checked,
guaranteed. Price: $595.00
