Note:

1) The 'M' in the specification code represents the current multiple

2) The mutual inductance function is only available in two specifications: 1 (2) A and 1.5 (6) A. The rated secondary current of the transformer is 5A

Example of ordering:

If the customer requires the DTSD607 three-phase four wire electronic multifunctional energy meter with a voltage of 3 × 220/380V and an accuracy level of 1,

If the current specification is 1.5 (6) A, the corresponding ordering code is DTSD607MQ16M4H

A three-phase electronic multifunctional energy meter consists of a measuring unit and a data processing unit

The design and structure of the electric energy meter can ensure that it can be used under rated conditions without causing any danger
