Each outlet metering unit is used for load measuring (VT1808) and/or allows to switch on/off or reboot up to 8 different loads (VT1908).
It is possible to connect some sensors and mount a GSM modem.
Latching relays 10А
Switching on/off
Environmental monitoring
Outlets С13
Built-in HTTP, HTTPs interface
Built-in SNMP v.1, v.2c, v.3
GSM modem
Emergency and/or alternate shutdown
Simple installation and easy connection
Configurable logic of switching
Latching relays in conjunction with possible power reservation 12V using a battery, allows the system to compensate for short-term voltage dips (220-240V) without changing the position of the relays.
Programmable logic allows specifying the use of consecutive or one-time mode for the inclusion of electric loads. Consecutive inclusion with a programmable delay of electric loads reduces starting current.
Units comparison chart
VT1808 (metered) and VT1908 (managed) are master modules and cannot connect. For scalability please use extension modules and embedded modules.
