Bottom meter with RF+MBUS,it's two-phase three-wire sts meter.
The DTZY876 is designed specially for Ecuador market. Main cover&terminal cover are made of transparent polycarbonate, resistant to UV rays (IEC 60068-2-5) and flame retardant.
Is split type, consisting of two parts, the MCU(Metering & Control Unit) and CIU( Customer Interface Unit). The CIU is installed within consumer’s home, while MCU is installed in a meter cabinet away from consumers.
20 digit (Standard Transfer Specification) STS encryption.
DLMS / COSEM standards compliant.
Disconnects on main cover&terminal cover open.
Configurable two modes(prepayment and postpayment).
Events record such as opening mail cover&terminal cover, current reverse , overload, overvoltage, overcurrent.
Ultrasonic welding and 2 screws of type unidirecctional on main cover.
Maximum demand and load profile measurement.
12 selfreading.
Communication downlinked( between MCU and CIU) is RF+MBUS.
Digits: 6 integers + 2 decimal.
