I. Product Features
The programmable bidirectional DC power supply features a modular design, digital DSP control, and high‑precision current and voltage sensing. It combines source and load functions, enabling it to both supply DC power to a load and feed electrical energy back into the grid in a pollution‑free manner. During charging, PWM soft‑switching technology enhances system efficiency and reduces losses; during discharging, the unit returns the battery’s stored energy to the grid, achieving energy‑saving regenerative discharge.
II. Application Areas
Home appliance sector: testing and durability testing of home appliances;
Telecommunications field: testing and aging of communication power supplies and electronic communication products;
Aerospace sector: Aging tests for aerospace electronic products (such as drones and motors for low-altitude aircraft, etc.);
LED field: LED drivers, aging tests;
Research fields: Testing and electrical experiments conducted by research institutions, universities, certification bodies, and other organizations.
Laboratories, production lines, charging rooms, aging rooms, and other facilities that require a long-term, stable DC power supply;
In the field of automated testing: in automated test systems, DC power supplies provide output power to the device under test.
III. Power Supply Features
It employs a bidirectional, independent AC/DC module design and a front‑in, rear‑out airflow configuration to extend fan life. An optimized air‑flow path enhances heat dissipation. A high‑performance DSP controller delivers precise control, while an efficient control algorithm reduces losses and improves system stability. The device features fast output response, low ripple, high power density, and excellent stability.
