PCB Varistor for Aseko Control Systems

The varistor is an electronic protective component mounted on the printed circuit board of Aseko control units that absorbs short-term overvoltage spikes and protects the sensitive control electronics from damage. Replacing a damaged varistor is an essential service step after power surges or mains failures, which can cause it to short-circuit permanently. The original part guarantees compatibility with Aseko unit PCBs and the correct varistor value to protect the entire circuit. Replacement requires basic knowledge of working with electronics and desoldering the component from the board. We recommend entrusting the service to an authorized technician.
