hes oct 19 6Think you’re safe? Wolf Safety voltage alerts remove doubt

Working in potentially explosive atmospheres is hazardous enough without concerns that the voltage being supplied to temporary lighting is no longer within certified limits.
How can anyone be absolutely sure what voltage is being supplied, especially in a typical, long cable FPSO situation?  Could it be one volt more or less than the certified safe range? (Read More)


Reassurance is now available from Wolf Safety, whose latest technology gives immediate warning when voltage either slips below or exceeds certified limits, even by just one volt.

Their SOVI™ technology - it stands for Safe Optimal Voltage Indicator – removes all doubt, giving operators the confidence that temporary lighting is operating safely, effectively and at the optimal voltage.

Unique to Wolf Safety products, the groundbreaking technology is now incorporated into its ATEX and IECEx certified Hazardous Area Temporary Lighting range, further enhancing safety in potentially explosive atmospheres.  

It also ensures that a lighting solution is operating effectively and at the optimal voltage.
In the unlikely event that a light is operating at a voltage above the maximum certified limit the beam will pulse from bright to dim, giving a clear warning that action is needed to ensure that work can continue safely in the hazardous area.

It’s more likely that issues will arise at the lower end of the voltage range. If too many 24-volt lights are strung together and the transformer is overloaded, voltage could drop below the optimal level and light output will reduce incrementally.

If this does occur, SOVI™ ensures the light will pulse bright, indicating that the lamp is not operating at its optimal voltage rang, though the light itself is still safe as it is certified down to zero volts.

This differs from other ATEX lights, where a reduced voltage supply can lead to the light operating outside the certified voltage range.

Wolf Safety’s clear, visual warning system and certification down to 0 volts enhances user safety even further in hazardous areas.
