Product description

Overview

The YO Power measures AC ﬂowing through devices connected to the electricity grid. With one YO

Power it is possible to measure the current simultaneously (e.g., in two three-phase, six single-phase,

one three-phase and three single-phase devices, etc.). It is possible to install current clamps without

knowing the direction through which the current ﬂows. Wireless communication eliminates the need

for additional wiring or conversion of existing installations. By means of the application algorithm

developed by the Yosensi Team, and despite the limitations of data transfer in the LoRaWAN

network, it is possible to establish accurate mapping of current and power consumption.

Device sticker placed on the right side of the device enclosure contains information about model,

version, LoRaWAN region and 3 parameters important in case of device identiﬁcation and

conﬁguration:

- DEV EUI: unique device identiﬁer required to connect via OTAA activation type to LoRaWAN

- DEV ADDR: address required to connect via ABP activation type to LoRaWAN

- BLE MAC: bluetooth physical address

Current

YO Power offers automatically switchable measurement ranges: 2 A, 10 A, 50 A, 100 A., which

results in even greater precision when measuring current. Each channel can measure current over

different measuring ranges simultaneously. The YO Power has measurement inputs with specialized

integrated circuits (e.g. specialized analog-to-digital converters) that ensure high measurement

accuracy.

Figure 4 Current ﬂow on second channel of the device exemplary chart.

Power consumption

Power consumption measured by YO Power and attached to it CT clamps is a value calculated for

each hour for 230 V and current ﬂowing on each channel. It helps monitor customers how much

power is consumed by the devices every hour and check anomalies in the electric network.

SYMBOL

DESCRIPTION

Device is marked with a symbol saying that electrical and electronic

products may not be mixed with unsorted household waste. Remember

that batteries used to power the device must be treated at a specialized

treatment facility.

Remember about possible electrostatic discharge when replacing battery,

connecting input or doing some other operations near inside electronics.

Be careful while handling the device – dropping it may cause damage that will

affect the sensors and other electronics inside.

When installing the device on the wall remember to wear adequate protective

equipment.

To maintain the level of protection device cover screws must be properly

tightened. Device shouldn’t be used without cover.

Any actions inside the device's enclosure (excluding replacing batteries) must

be performed by trained personnel only.

Clean the device only with damp cloth.

Device is intended for outdoor and indoor use.
