AC Current sensor
The AC current sensor is used for the continuous monitoring of the power supply in the range of 90 to 240V AC. This sensor also detects power outages and voltage drops.
Easy installation
Connect the power monitoring sensor using the included sensor cable. Simply plug the USB connector of the supplied RJ11/RJ12 cable into the USB port on the sensor unit. Plug the RJ11/RJ12 connector of the cable into an available sensor port on your Ethernet-based monitoring system 50/100/100II/100III (DC)/300/500 II (DC).
Then simply plug the AC power sensor into a free 230V wall outlet.
Editor's Note:
To ensure reliable notification of voltage fluctuations or power outages, the monitored outlet/power strip must not be protected by a UPS (Uninterruptible Power Supply). The Monitoring System 500 II can be equipped with a backup battery. In the event of a power outage, this device will be powered for up to 5 hours.
All other measuring and monitoring devices must be connected to a UPS (Uninterruptible Power Supply) to enable notification and alarms in the event of a power failure.
Extension of the sensor cable AC alternating current
The 1.8-meter sensor cable can be extended up to 100 meters if desired. Suitable extension cables for the AC sensor can be ordered here in our online shop.
The following five threshold values are available: "Alarm Level (Low)," "Warning Level (Low)," "Normal,"
"Warning Level (High), and "Alarm Level (High)."
Next, please enter a custom name for the sensor and then click "Apply."
Clicking the floppy disk icon (top right of the web GUI) will permanently save the settings to non-volatile memory.
Setting up the AC sensor
The AC current sensor is automatically detected by all IP-based measurement and monitoring devices from Didactum with the support of the Auto Sensing function. Log in to the monitoring device using the web browser of your smartphone, tablet, PC, or notebook.
In the multilingual web interface under "System Tree", the AC current sensor will then be displayed under the menu item "Autodetect" .
The displayed icon "V" stands for Voltage. Open the AC current sensor menu by clicking to configure this sensor individually.
Sensor Settings Menu:
Name | The sensor name is automatically assigned and can be changed |
ID | Identification number of the AC Voltage Sensor |
Type | The sensor type is displayed here. This sensor belongs to the Voltage Sensors |
Class | Display of the sensor class: Analog, digital CAN, Switch, Discrete |
Hardware Port: | Display of the sensor port on the monitoring system to which the sensor is connected. |
Current State: | Current status of the AC Voltage Sensor (Normal / Alarm) |
Current Value: | Real-time display of the applied AC voltage |
Hysteresis Type: | Advanced configuration options (from firmware 2.7.3 and higher) |
Hysteresis functions / measured values alternating between 2 threshold values
Starting with firmware version 2.7.3 and higher, the IP-based measurement and monitoring devices offer expanded configuration options.
This allows for a significant reduction in the number of notifications and alarms triggered by continuously changing sensor states or readings ("Warning level (high)" => "Alarm level (high)" => "Warning level (high)" etc.).
Set up alarm notifications in case of critical voltage or power outage
Each network-based measuring and monitoring device operates stand-alone. No additional software needs to be installed on a smartphone, tablet, laptop, PC, or server for operation. Notifications and alarms in the event of critical voltage or power outages can be sent by the monitoring device via SNMP traps, emails (to up to 10 different email addresses), and SMS messages (via GSM/LTE modem or Web to SMS/SMS Gateway).
If desired, a siren with an integrated strobe light can also be activated via an automatic relay circuit.
