Staco VARIAC Variable Transformer 1000 and 1200 Series

STACO’s 1010B variable transformer coil operates on 120 volts and is rated for constant current of 10 amperes. The 1020B variable transformer coil operates on 120 or 240 volts and has a constant current rating of up to 3.5 amperes. Both variable transformer types include coil tapping arrangements allow for 0 to input line voltage or 17% above line voltage. The 1020 taps allow the unit to double the input voltage if desired. 

Staco 1210B variable transformer coil operates on 120 volts and is rated for constant current of 12 amperes. The 1220B variable transformer coil operates on  240 volts and has a constant current rating of up to 5 amperes. Both variable transformer types include coil tapping arrangements allow for 0 to input line voltage or 17% above line voltage.  

All these variable transformers may be operated from 50-1500 hertz with no reduction in output current.

Uncased 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, which have a "CT" suffix, feature the protective cover over the coil assembly and a terminal box cover with knock-outs to accept conduit.

Motor driven variable transformer units are available in single, two and three ganged variable transformer assemblies; cased or uncased styles as identified by the prefix "M" in the type number. If a motor driven model is ordered, be sure to prefix the part number with the desired travel time from (0 to maximum output) 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.
