- 3.4 to 244 KVA
- 28 or 50 Output Amps on Single Uits
- Up to 450 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)
The 5000 Series Variable transformers are designed to control large KVA requirements. The 5010/5011 operates on 120 volts and is rated for constant current of 50 amperes. The 5020/5021 operates on 240 volts and constant current of 28 amperes. The 5000 Series units have coil tapping arrangements allowing output voltage from 0‑117% of line voltage. They can be operated at frequencies between 50 and 400 Hertz with derating at higher than rated frequency.
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 Staco's Nema 1, dripproof, fully front accessible "E" enclosure is available.
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, single phase 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.
