Staco VARIAC Variable Transformer 2510 and 2520 Series
The 2510/2520 Series Variable Transformers represent a compact high current variable transformer design. The 2510, 120 volt variable transformer coil is rated at 25 amperes for constant current loads; while the 2520, 240 volt variable transformer coil is rated at 10 amperes for constant current loads. Constant impedance ratings are listed in the specifications. They can be operated at frequencies between 50 and 2000 Hertz with derating at higher than rated frequency (See Table for frequency derating).
Uncased variable transformer models have the shaft extending from the base end. This shaft is fully adjustable and can be extended from either end for general utility mounting. Cased styles are available in either "C" style (featuring protective screening over the coil assembly only) or the "CT" style (which also includes a terminal box cover with knock-outs to accept conduit).
Motor-driven variable transformer models are available in single, two, or three ganged assemblies in cased or uncased styles as identified by the prefix "M" in the part number. If a motor driven model is ordered, be sure to prefix the part number with the desired travel time from 0 to maximum of 5, 15, 30 or 60 seconds. The synchronous motor is designed for operation on 120 volts, 50/60 Hertz, single phase lines and draws approximately 0.3 amperes.
Portable models with case, cord, receptacle, switch, light and fuse are available. Goto Portable Variable Transformer Page for details.
