About Us
Royrex Technologies (Shenzhen) Co., Ltd.
Founded in 2004, Tongmen Electronics emerged from a Dongguan University research team aiming to counter the foreign monopoly in China's instrumentation sector. Despite initial challenges, the company successfully launched the eTM-305 product through independent research and development, becoming a national high-tech enterprise in 2017. With about 100 new products introduced annually and the establishment of subsidiary companies, Tongmen continues to expand its presence. The company played an active role during the 2019 COVID-19 pandemic by launching products such as the mask machine ultrasonic analog machine. As Tongmen evolves into a group company, it remains committed to creating high-quality and innovative products in China's power electronics sector.
Royrex Technologies (Shenzhen) Co., Ltd. belongs to Dongguan Tongmen Technology Co., Ltd. and is one of the subsidiaries, which is mainly responsible for docking and serving overseas customers and projects.

programmable DC power supply
A programmable DC power supply is a process in which instructions are compiled and fed into a machine in a sequence of operations so that the machine runs automatically according to the instructions. What is a programmable DC power supply used for? Programmable DC power supply or power supply. As for programme control, this means that the output of the power supply can be programmed and controlled. Programmable DC power supplies can generate stable high-power industrial frequency voltage and current signals with adjustable range, frequency and phase angle. It is mainly used for testing and verification of current, voltage, phase, frequency and power meters; it can also be used to verify the basic error, creep and sensitivity of standard power energy meters.

High Power Programmable DC Power Supplies
In order to obtain a higher DC voltage, high-power programmable DC power supplies often use DC power supplies in series. At this point, the total potential is the sum of the potentials of each power supply, and the total internal resistance is also the sum of the resistances of each power supply. Due to the increase in internal resistance, high power programmable DC power supplies can usually only be used in circuits where the required current intensity is small. In order to obtain a higher current intensity, DC power supplies of equal potential can be used in parallel. At this point, the total potential is that of a single power supply, and the total internal resistance is the parallel value of the resistance of each power supply.
