An ‘Aiding’ and ‘Opposing’ Magnetic Amplifier is connected across the main transformer to either increase or reduce the input voltage should it go high or low. This is achieved by increasing or reducing the magnetic inductance in the two cores. The Control Amplifier Sensor will detect the input fluctuations and then inject a DC current into the two respective amplifiers to either increase or reduce its inductance.
Reducing the inductance will increase or reduce the output voltage and vice versa. The Sensing Amplifier monitors the output voltage continuously and automatically adjusts the DC currents through the control coils, thereby ensuring that the output voltage is kept constant.
The Filter, in conjunction with the inductance of the magnetic core, forms an extremely effective means of suppressing high energy spikes and other mains borne noise.
- Solid State – with no moving parts – virtually Maintenance Free
- Ultra-fast speed of response to voltage changes
- Extremely accurate output voltage - accuracy better than 1%, typically 0.5%
- Less price competitive when compared to servo electronic design based systems
- High weight to kVA ratio compared to servo electronic designs
Being a considerably more pricey design topology when compared to our more popular ranges of Servo Electronic and Magnetic Induction based solutions, Saturable Reactor based systems are primarily intended for truly ‘Mission Critical’ applications where a solid state solution is required and the load equipment is ultra-sensitive to the vagaries of the incoming mains supply and demands a highly stable and clean supply voltage - eg. Laboratory and testing equipment and ‘High-Tech’ manufacturing processes.
Ashley-Edison (UK) Saturable Reactor based Solutions
Given the extremely high cost of these type Stabilisers, and given the advances made in recent years in the design of Static Electronic solutions, Ashley-Edison no longer offers Saturable Reactor based solutions.
