TD3740 Energy Meter Durability Test Device

Name: TD3740 Energy Meter Durability Test Device
Brand: TUNKIA
Rating: 5.0 (44 reviews)

TD3740 is a device specially designed to meet the durability test of R46 single-phase/three-phase AC energy meters. The device consists of a standard power source, a meter rack, etc., including three types: TD3740-S (single-phase), TD3740-T (three-phase) and TD3740-ST (single-phase and three-phase compatible). The power/electric energy accuracy is class 0.05. It can be used with high and low temperature test chambers to complete energy meter durability tests and other testing projects.

1. Summary

2. Features

• Three-phase output: maximum voltage 456 V, maximum current 120 A.

• High reliability: Continuous operation at the load point (1.1Umax, Imax) for 1000h can ensure the stability of the value output.

• Phase diagram display: The phase between the three-phase electricity can be adjusted arbitrarily, and it can display phase diagram.

• The software has comprehensive data management functions, convenient data retrieval, and automatic backup function.

• The software can output statistical reports such as verification certificates and test reports; it supports document saving and printing in multiple formats.
