In today’s world of sensitive and increasingly complex electronics that require ever more complicated chips to run its functions and features, so consequently there is also a need to pack even more transistors into those chips into an already tiny space. So the only solution is to make those individual transistors increasingly smaller and smaller to be able to fit them in. Unfortunately as their size shrinks so will their robustness to withstand power supply over-voltage problems as they turn more fragile. Hence an increasingly important topic has become the protection of electronic components from DC Mains borne over-voltage surges and spikes that could cause irreparable damage to the equipment.

WITH THE CURRENT GLOBAL ELECTRONIC CHIP SHORTAGES, BEST TO PROTECT YOUR EXISTING EQUIPMENT TO AVOID
BEING CAUGHT IN A SITUATION OF DAMAGE WITH NO SHORT TERM REPLACEMENTS AVAILABLE FOR A GOOD WHILE !

When you wire-in this OVP Module between your equipment and its DC Power Source your Sensitive and Expensive Electronics will be Fully Protected against any momentary or continuous Over-Voltage or Current Overload conditions, with Fully Automatic Self-Restoring once the fault is corrected. And additionally it also effectively protects against a wide range of other DC Mains Induced Transient Voltage Surges, Spikes and Pulses

AFFORDABLE PROTECTION THAT CAN BE JUSTIFIED FOR ANY ELECTRONIC EQUIPMENT
PLUS: One OVP Module Alone Can Easily Protect Multiple Electronic Devices
as it can handle loads of 10Amp Continuous, and Up to 20Amp Max Peak Load
