Crystal Growing
Control Concepts, Inc. SCR power controllers are currently being used to heat crucibles in some of the most advanced crystal growing processes invented. We work with multiple OEMs – most recently in sapphire production.
These processes require high power control resolution and extremely precise control sustained consistently for 20-60 days. Our core values – performance, reliability, and support - are showcased vividly in this fascinating industry.
| Model | Phases | Firing Mode | Output | Voltage | Current Low | Current High | Highlights |
|---|---|---|---|---|---|---|---|
| MicroFUSION Three Phase | Three phase | Phase angle, Zero cross, Zero Cross Transformer Mode, Fast Zero Cross | AC | 24-690 VAC (CE), 24-600 VAC (UL), 45-65 Hz | 8 | 400 |
MicroFUSION is an ultra-compact high performance digital SCR controller that adapts to the analog environment as well as the digital environment. |
| FUSION Three Phase (AC) Power Controller 500 - 1200A | Three phase | Phase angle, Zero cross, Fast Zero Cross | AC | Auto-Ranging Line Voltage 24-600 VAC, 45-65 Hz | 500 | 1 200 |
24 - 600 Vac. A microprocessor-based SCR controller operating both analog and digital interfaces. A phase angle or zero cross fired SCR controller which linearly controls, with respect to the setpoint, the AC voltage, current, or true power applied to a three phase electrical load. The 3 phase controller can be ordered in either 2 or 3 leg control with 2 leg being limited to zero cross firing. Control is achieved for 3 leg by three pairs of inverse parallel SCRs or in 2 leg by 2 pairs of inverse parallel SCRs. |
| FUSION Single Phase (DC) Power Controller | Single phase | Phase angle | DC | Auto-Ranging Line Voltage 24-600 VAC, 45-65 Hz | 45 | 1 080 |
24 - 600 Vac. A microprocessor-based DC SCR controller operating both analog and digital interfaces. A phase angle fired controller which linearly controls, with respect to the setpoint, the DC voltage, current, or true power applied to an electrical load. Control is achieved by means of a half controlled SCR bridge. |
| FUSION Three Phase (DC) Power Controller | Three phase | Phase angle | DC | Auto-Ranging Line Voltage 24-600 VAC, 45-65 Hz* | 60 | 1 400 |
24 - 600 Vac. A microprocessor-based DC SCR controller operating both analog and digital interfaces. A phase angle-fired controller which linearly controls, with respect to the setpoint, the DC voltage, current, or true power applied to an electrical load. Control is achieved by means of a six SCR bridge with freewheeling diode. |
| FUSION Single Phase (AC) Power Controller 500 - 1200A | Single phase | Phase angle, Zero cross, Fast Zero Cross | AC | Auto-Ranging Line Voltage 24-600 VAC, 45-65 Hz | 500 | 1 200 |
