2 Wire VDR Surge Protection Electricity Prepayment Meter With Ultrasonic Welded Case
Build-in with up to 16kV / 8kA surge protection VDR,the DDSY168 is a one phase two wire meter designed for unique African and South American environment prone to lightening or other line surges. It is finished in a compact BS footprint mounting enclosure of flame retardant polycarbnonate , with 30Vm withstand of RF immunity, allowing to be installed in very harsh environment. The meter is widely used for residential and light commercial , tenant submetering scenarios.
The feature rich device is built with tamper sensors to detect cover open, reverse connection, outage, etc. It allows a utility or service provider to make setting for payment control parameters such as emergency unit, free unit, arrear repayment, and low balance warning.
