Description:
The Holley DTSD545 is a three-phase, four-wire direct-connected smart electricity meter rated 10(160) A, designed for residential, commercial and light-industrial supplies where remote reading and supply control are required. It measures active and reactive energy in both directions and communicates over DLMS/COSEM via its built-in GPRS modem, an RS485 port and an optical port. An integrated 160 A load-control relay allows remote or local disconnection and reconnection, with configurable over-power and over-voltage tripping. Time-of-use tariffs, load profiles, monthly billing snapshots and comprehensive event logs make it suitable for prepaid-to-smart migrations, sub-metering, utilities and estate or landlord billing.
