DDS238-2 ZN/S
DDS238-2 ZN/S Single Phase DIN-rail Meter

This product has been discontinued and removed from our shelves.

The DDS238-2 ZN/S single phase DIN-rail meter conforms to the technical requirement of IEC61036. It is used to measure variable parameter and single phase two-wire AC active energy.
With the data communication rules designed as per the requirement of DL/T645 or MODBUS-RTU, this small-size meter also has many good properties like, decent stability, high durability, high overload capability, and low power loss.

Basic Function
1. The single phase DIN-rail meter can display realtime voltage, current, power, power factor, and frequency.
2. Measurement of bi-directional total active energy and the measurement of reverse active energy in the total active energy are the main functions of this product.
3. The device comes with a backlit LCD display.
4. It has pulse LED indicator for working status indication. The pulse output is available with optical coupling isolation.
5. It is designed with infrared and RS485 communication port, and supports 35mm Din-rail installation method.

Optional Function
1. Optionally, the single phase DIN-rail meter can be designed to measure both the total forward active energy and reverse active energy.
2. Energy-reset function. This optional function won't cause any difference on the display of total energy.
