DTSD5-R学阶段的电子能米

The use of innovative metering technology provides cost-effective metering that is highly secure and maintains a high degree of accuracy over its full operating range. DTSD5-R Electronic energy meter is suitable for CT or direct connected, residential, commercial and even light industrial polyphase applications. Cost Effective Revenue Metering Designed to provide cost-effective functionality the DTSD5-R combines proven metering technology with a reliable electro-mechanical register. The metering system is 2-element for 3 phase 3 wires system and 3-element for 3 phase 4 wire system. Meter is programmed on the measurement mode at the factory prior to dispatch: The total energy measurement from the three phases can be optioned in vector consumption or absolute value consumption. Records import and export energy flow in separate registers, and add the values in both directions as the labeled energy consumption. Reliability Digital measurement technology with proven long-term capability, use of long life components and special care in the manufacturing process guarantee consistent accuracy and reliability over the meter's life time. Meter case Made of self-extinguishing polycarbonate and can be recycled at the end of the meter life. It assures double insulation and up to IP53 protection level against dust and water penetration. Legible Register The meter is equipped with one 7-digit drum- register (6+1or 5+2 decimals). offers excellent readability and reliability and is even suitable for self-reading purposes. As an additional advantage, the register can be read when power is absent . Communication Port Equipped with an optical port and Rs485 (optional) for meter reading. Anti-tampering Feature -Meter cover overlaps the base until the ground plane -The meter measures the absolute sum of total energy even energy is reversed -Indication of reverse energy flow -Independent seals of the meter body and terminal cover. Alarm - Power outage among three phases - Incorrect polarity of current - Power reverse - Phase rotation
