Our microprocessor-based SCR power controllers, FUSION, Compact FUSION, and MicroFUSION, provide reliable, precise power control in either an analog or digital environment.
Note: our microprocessor-based controllers like FUSION and MicroFUSION operate in both analog and digital environments.
Three Phase, Zero Cross:
The term Zero-Cross (synchronous operation of SCR's) is derived from the fact that the SCR's are turned on only when the instantaneous value of the sinusoidal wave is zero. In Zero-Cross operation, power is applied for a number of continuous half-cycles and then removed for a number of half-cycles to achieve the desired load power in the same manner as power would be controlled with a mechanical switching device. The frequency of the on-off cycles can be extremely fast because there is no limit to the number of switching operations the SCR can perform.
3 Phase, Phase Angle:
In phase-angle control, each SCR of the back-to-back pair is turned on for a variable portion of the half-cycle that it conducts. Power is regulated by advancing or delaying the point at which the SCR is turned on within each half cycle. Light dimmers are an example of Phase-Angle control.
The primary use of solid-state relays is to switch AC loads, whether it's for purposes like toggling AC power on and off, adjusting lighting intensity, regulating motor speeds, or any other scenarios requiring power management. These AC loads can be efficiently managed using a solid-state relay with a low DC voltage input, offering extended durability and rapid switching capabilities.

Power Phase Angle
In phase-angle control, each SCR of the back-to-back pair is turned on for a variable portion of the half-cycle that it conducts. Power is regulated by advancing or delaying the point at which the SCR is turned ON within each half cycle. Light dimmers are an example of phase-angle control.
Phase-angle control provides a very fine resolution of power and is used to control fast responding loads such as tungsten-filament lamps or loads in which the resistance changes as a function of temperature. Phase-angle control is required if the load is transformer-coupled or inductive.
Zero-Cross
The term zero-cross or synchronous operation of SCR's is derived from the fact that the SCR's are turned on only when the instantaneous value of the sinusoidal waveform is zero.
In zero-cross operation power is applied for a number of continuous half-cycles and then removed for a number of half-cycles to achieve the desired load power in the same manner as power would be controlled with a mechanical switching device.
