Practical Control Solutions
presents a custom range of thyristor power controllers available for OEM industrial electrical heating applications. These robust thyristors can be customised for specific application requirements.
Comprising of one, two and three phase models with currents up to 800 amps at 690V AC, the custom thyristor power controllers are equipped with microprocessor control and can be run as a solid state contactor, acting as an on/off switch with zero volt turn on and zero current turn off.
Alternatively they may be operated as a zero cross burst controller with output proportional to a 4-20mA, 0-20mA or 0-10V DC control signal. Internal semiconductor protection fuses are supplied standard with the thyristor power controllers while a heater break alarm with internal current sensing is available as an option for the detection of partial or total load failure.
The custom thyristor range can also be utilised with the Revo-PC power management system, which synchronises multiple loads so that the supply ‘sees’ a near constant load with near unity power factor and without peaks whilst minimising harmonics and flicker.
The Revo-PC power management system also incorporates smart power limit, which uses predictive algorithms to maintain total power consumption below a preset maximum, enabling electricity consumers who are on a maximum demand tariff to minimise their energy costs.
