Power Factor Controller CX plus
The Power Factor Controller CX plus is a further development of the BLR CX relay being sold more than 100 000 times. It offers everything for an uncomplicated operation of compensation systems.
The focus in further advancement was on usability and elimination of sources of error which can occur when using the device for the first time.
The user is given the opportunity to choose a user controlled initial setup when powering on the device. The CX plus algorithm guides the user through the menu items to query and set all necessary parameters for the regulation. A successful setup is now possible without a manual.
The more powerful processor of the CX plus leads to a significantly improved outcome during initial setup. This is necessary for a correct detection of the phase offset angle which again is necessary for detection of the power, cos ϕ and step sizes.
The well-proven wide-range power supply known from the BLR CX is also used in the CX plus with a voltage range of 90 – 550 VAC.
The detected capacitor step sizes are verified and updated during operation so that it is always compensated with actual values. This way the ageing of the capacitors is detected and an alarm is given and the relevant capacitor stage locked preventively when dropping below a specific capacitance.
Additional setups can be made in a password-protected expert setup in the areas of measuring, regulation, alarms or output steps.
The patented Best Fit algorithm delivers the best result of the power factor cos ϕ with the lowest amount of switching cycles. When having the capacitors of equal size , the switching times and the duty cycles are distributed evenly. This extends the life span of the capacitors and contactors, thus saving your Investment.
