- 4.2 to 305.2 KVA
- 35 or 60 Output Amps on Single Units
- Up to 540 Output Amps on Ganged Units
- 120, 240, or 480 Input Volts
- Multiple Output Voltage Ranges
- Operation up to 400 Hz (See Engineering Guide for Details)
Variable transformers of the 6000 Series are designed for larger KVA requirements. The 6010/6011, 120 volt unit is rated for constant current of 60 amperes. The 6020, 240 volt unit is rated at 35 amperes for constant current loads. All single units have coil tapping arrangements allowing output voltage
from 0 to line voltage or 17% above line voltage.
Adjustable shaft design on manually operated models permits back‑of‑panel or bench mounting. Terminals are 1/4" screw type. For single and two ganged units, case styles are available in either "C" style, which encloses only the coil, or the "CT" style, which provides protective housing for both the coil and terminal board. Knockouts are provided in the terminal board housing to accommodate conduit or cable connections. For three ganged and above, we offer our Nema 1, dripproof, fully front accessible "E" enclosure.
Motor‑driven models are available from single thru 27 ganged assemblies; cased or uncased (identified with the prefix "M" in the part number). The synchronous motor is designed for operation on 120 volt, 50/60 Hertz lines and draws approximately 0.3 amperes. To meet a wide range of application requirements, standard motor speeds of 5, 15, 30 and 60 seconds are available depending upon the size of the variable transformer.
