3021B Three Phase Power Controller
- Line voltage compensation holds load voltage constant with changes in line voltage
- Sync-Guard™ smoothes out line current draw when multiple controllers are in use.
- Compact and economical
- Fast cycling distributive control improves heater life and reduces temperature variations.
- 2500 Vac RMS isolation between input/output and line voltage/heatsink.
- Natural convection.
0-5 VDC, 0-10 VDC, or Potentiometer*
Available as a single phase as a 1021B.
Electric ovens, furnaces and kilns. An excellent contactor replacement and may be used in all resistive heating applications.
Even greater density can be achieved by using the 3021B on our 1600 family heatsink. Up to six 70 amp controllers, all within a 7.28" x 14.5" footprint!
