Description:
The Eastron SDM320C-LR is a single-phase DIN-rail smart energy meter with a built-in LoRaWAN radio and an internal 100 A relay, so tenants can be read and switched remotely without any wiring back to a data logger. It measures import and export energy plus all the usual electrical parameters, uploads up to 19 readings automatically on a set interval, and is MID Class B approved for billing. Ideal for LoRaWAN-based tenant metering, load control and disconnect-on-arrears in apartment blocks, estates and small commercial units. This listing is for a factory box of 50 meters at a bulk unit price of R1,600 incl. VAT per meter.
