SONOFF SPM-Main išmanioji energijos matavimo sistemos valdymo panelė, Wi-Fi

SONOFF SPM-Main is the main device of the SONOFF smart metering system, designed for use with the SPM-4Relay expansion module. Supports up to 128 channels. With energy consumption accounting. SONOFF smart metering system enables network overload protection, network accounting monitoring and electricity consumption statistics collection and storage. It supports up to 128 channels (up to 32 SPM-4Relay modules), 20A maximum current for each channel, allows you to monitor 180 days of electricity consumption data, and manage each channel separately. It is a high-performance professional smart home tool that allows you to monitor the electricity consumption of residents or tenants; designed for homes, office buildings, industrial buildings or even shopping malls.Note: the device requires at least one SPM-4Relay module to operate., which is purchased separately.Features:This central station of the smart energy metering system communicates with the 'eWeLink' cloud via Ethernet or Wi-Fi, and with SPM-4 relay modules via RS-485. One central station allows you to connect up to 32 expansion modules and supports up to 128 channels of 20A control and accounting. The SPM-Main central station allows you to use 8Gb-32Gb SD memory cards, where you can safely store consumption data. SD cards are purchased separately. Remote on / off - you can turn all channels on and off remotely anytime and anywhere. Synchronization status - check the actual relay status (on or off) using the app. The electricity consumption data of home equipment can be downloaded for accounting. LAN mode is supported. Mounted on a DIN rail, like the relay module, suitable for an electrical cabinet. Housing material made of non-flammable PC V0 safety class plastic. Protection for all channels against overload, overvoltage, overcurrent.Technical data:Compatible with: Sonoff SPM-4Relay. Voltage: 100V~240V AC. Frequency: 50/60Hz. Current: max. 50mA.
