► Maximum Output Capacity: 576 V / 120 A, with fundamental frequency ranging from 45 Hz to 100 Hz
► Minimum Current Output: As low as 0.2 mA, meeting the starting test requirements for Class D/E energy meters with Imax of 1.2 A
► Three-Phase Power Adjustment: Supports both unified and per-phase adjustment of voltage and current outputs. Fully automatic range switching and load matching simplify testing
► Multi-Position Test Bench: Available with 3, 6, 12, or 16 meter positions. Each position is equipped with power output, energy pulse, and communication interfaces

TD3650 is a new-generation comprehensive three-phase energy meter testing device designed to meet the requirements of OIML R46, the new Chinese national standard GB/T 17215.211, the type evaluation outline JJF 1245-2019, and the latest technical specifications for smart meters from State Grid and China Southern Power Grid.
It mainly consists of a three-phase precision standard power source, a multi-position meter test bench, a control console, an optional computer, and dedicated software.
Available in two accuracy classes—0.02 and 0.05—it supports fully automatic simultaneous verification of 3 to 16 three-phase electronic energy meters, smart meters, or IoT meters with identical voltage/current ranges but different meter constants.
