The DTSY150-S offers options for extended surge protection for lightening up to 13Kv with a bulid-in 6.5kA VDR and a wide voltage working range. It is intended for unstable grid voltage environment such as African and Central American continent where brownouts and voltage dips are extremely freuquent. The meter works in a three phase four wire or three wire(optional) network with 100 Amp per phase, and 30Vm withstand of RF immunity, allowing it to operate in very severe environments. It is a perfect revenue protection device for sub-metering of residential, light commercial and industrial applications.
