Product Features
Overview:
ADF400L series multi-user electrical energy meters can be directly connected for 12-phase or 36-single-phase measurements through modular assembly, or for a combination of direct and transformer-based measurements. This series is favored by communities, schools, and businesses for its high accuracy, centralized installation and management, flexible installation, and non-interference. The meters also support pre-paid functionality. The product complies with standard GB/T 17215.322-2008.
Selection Instructions:
A main module can accommodate 36 circuits (12 three-phase, 36 single-phase, or a mix of single and three-phase not exceeding 36 circuits). A direct connection module provides one three-phase or three single-phase circuits, and a transformer connection module offers two three-phase circuits.
Customer Requirement: 5 three-phase transformers connected with three-way sensors, 2 three-phase connections direct, 5 single-phase connections direct, with pre-paid option. Selection Instructions: First, determine if the number of loops exceeds 36. Each transformer connection module has two three-phase circuits, so 5 three-phase transformer connections require calculation as 6 three-phase circuits, totaling 18 loops; 2 three-phase direct connections total 6 loops; each direct connection module has three single-phase circuits, so 5 single-phase direct connections require calculation as 6 single-phase circuits, totaling 6 loops. In summary, the total number of loops is 18 + 6 + 6 = 30 <= 36.
Product Model: ADF400L-5H2S5DY
Module Composition: Due to the two three-phase circuits of a transformer module, 5H requires three transformer measurement modules. 2S requires two direct connection measurement modules. One direct connection module has three single-phase circuits, so 5D needs two direct connection measurement modules. In summary, this model product includes one main module, three transformer connection measurement modules, and four direct connection measurement modules.
