As part of our effort to continuously improve our products, we are currently updating a number of them in order to apply the recommendations of IEC 61010-1 standard. This change is important in particular for devices that may be connected to the mains (240 V AC).
For these products, we are switching from a simple functional insulation (340V) to a reinforced safety insulation (3 kV),that ensures that even in case of transient over voltage thelow voltage circuits and the USB bus remain safe. The device documentation will be updated accordingly, including safety
The products affested by this change are:
The change has already been completed for the Yocto-Watt. It has no impact on the device dimensions, nor on its pricing. You can find pictures of the new Rev. B on the product page, as well as the updated documentation. Same URL as before: http://www.yoctopuce.com/EN/products/usb-electrical-sensors/yocto-watt
We are about to proceed to similar changes for the Yocto-Volt, Yocto-Amp, Yocto-PowerRelay and Yocto-MaxiPowerRelay within the coming 1-3 weeks.
For the Yocto-Amp and Yocto-Volt, this enhancement will unfortunately come with a price increase (+8.5%), as a change of PCB material was the only way to bring the proper level of insulation without modifying the device size.
On the Yocto-PowerRelay, the change will have no impact on pricing nor on dimensions, but to maintain the proper distance between PCB tracks, we had to swap the position of outputs A and B. Since this is a
functional change, the new version will be named Yocto-PowerRelay-V2. The old Yocto-PowerRelay will still be available for some time if needed.
On the Yocto-MaxiPowerRelay, the change will have no impact on pricing nor on dimensions. We had to remove the extra 2.5mm fixing hole in the center of the device, but the outer 3mm fixing holes remain unchanged, as well as the terminal blocks.
Note that other products such as the Yocto-LatchedRelay, Yocto-MaxiCoupler, etc will remain unchanged for now, but the documentation will expressly state that their use on the mains is possibly dangerous as they will not get a reinforced safety insulation.
