III. Product function details

3.1 Enhanced high-temperature heat dissipation, stable full-load operation in high-temperature environment

60A0110-5A3-4-0T focuses on optimizing the internal heat dissipation air duct and the layout of heat dissipation power components, equipped with a large-flow high-speed heat dissipation fan, with significantly increased ventilation volume, effectively removing the accumulated heat in enclosed electrical cabinets and high-temperature workshops. In summer high-temperature, dense equipment heat dissipation difference, and high ambient temperature sites, it can still output 110KW rated power continuously without the problems of ordinary power supply temperature reduction, frequent overheating alarms, and automatic torque limitation, greatly improving the stability of equipment operation throughout the year.

3.2 110KW high-power centralized stable voltage supply

High-power main circuit design, abundant output current, can simultaneously drive multiple groups of high-power servo axes to complete synchronous linkage, high-speed start-stop, and extreme heavy-load actions. Combined with high-speed voltage closed-loop control, regardless of grid fluctuations or load sudden changes, the 600V DC bus voltage remains highly stable, eliminating common faults such as servo jitter, speed deviation, positioning error, and multi-axis synchronization deviation from the power supply end.

3.3 Four-quadrant efficient grid-connected energy feedback

For lifting lowering, machine braking, and high-frequency start-stop of mechanical hands, quickly invert the regenerated electrical energy from the motor and send it back to the factory power grid for secondary utilization, completely eliminating the heat dissipation through resistors, significantly reducing the overall temperature rise of the equipment, further reducing the heat dissipation pressure in high-temperature environments, saving energy and cooling, achieving dual optimization of on-site usage conditions.

3.4 Multi-module parallel high-power expansion

Supports multiple units of the same model 0T high-temperature power module to be connected in parallel, the system automatically precisely balances current, no additional control unit is required, the networking is simple and stable. It can quickly build a 220KW, 330KW level super-large power supply system, meeting the centralized power supply of the entire heavy industry production line, large-scale equipment assembly, and convenient and efficient capacity upgrade and expansion in the future.

3.5 High-quality grid power optimization

VII. Installation and Usage Tips

6.1 Installation Requirements

Prioritize installation in locations with relatively good ventilation, leaving sufficient space for up-down-left-right convection cooling; strictly distinguish phase sequence for three-phase incoming lines and ensure reliable grounding; strictly prohibit reverse connection of positive and negative poles of the DC bus, and select large-sized, high-temperature-resistant power cables for wiring; use copper bars for unified connection of multiple machines to ensure uniform current distribution.
