DTSD1088H3 CDMA meter,
Three phase electronic multifunction watt hour meter

1. Introduction
The key features of the DT(S)SD1088H3-series meter (3P4W) are cost-effective multi-functional CDMA metering device for commercial and industrial applications. The meter offers the powerful functions such as TOU (Time-of-Use) metering, various energy and power measurements, huge metering/interval data and events recording, instantaneous measurement and instrumentation, tamper & fraud protection, and communication.

2. Metering capabilities
The meter can measure and record a billing data like energy and demand data based on a metering channel configuration which can set up to 4-channels. Also, the meter can measure the quadrant energy and the combination of each quadrant energy quantities. For more requirements, the demand measuring and recording channel can be set separately with the energy metering and recording channel.

1). TOU metering
The meter can adopt up to 8-tariff TOU metering capabilities including 8-switching points per day, 12-day schedules, 8-week groups, and more than 600-holidays. Additionally, the meter provides a unique TOU function that each metering and recording channels can be set to be an exclusive TOU program.
