Delta’s high-power power supplies to optimise cobots
3rd March 2025

Delta has introduced a series of high-power panel mount power supplies, the new PMS Series’ 750W, 1,200W, and 2,500W models. They feature optional 24V/48V voltage outputs and supports peak power, ideal for equipment that require extremely high instantaneous power when activating, including collaborative robots (cobots), motor drive, and other inductive-load applications.
They also have active current sharing to automatically adjust output power for parallel-connected power supplies. This would prevent the overloading issue that results in overheating or operation termination of power supplies, enabling stable operation for high-power automated industrial equipment.
These high power supplies are in a 1U low profile and come with a universal AC input voltage ranging from 85Vac to 264Vac. The PMS series is designed for installation in limited spaces. With a wide operating temperature range from -20°C to +70°C; these units also have shock and vibration certification IEC 60068-2.
The PMS Series panel mount power supplies feature built-in active PFC, which reduces unnecessary power loss and waste heat, lower damage of harmonic distortion, and ensure a stable power source. They also feature high efficiency, high power density, and compact design to be save more space for control cabinets. Their intelligent fan speed control ensures efficient cooling while maintaining low acoustic noise, suitable for end-user applications such as medical environments and retail sales.
Conforming to the PMBus communication protocol for real-time monitoring and remote control, thus ensuring instant warning for abnormal operation. They are certified to international safety standards such as IEC/ EN/ UL 62368-1 for audio/video, information, and communication technology equipment, ensuring a safe operation for IT equipment. They also comply with SEMI F47, making them suitable for critical factory automation processes and semiconductor equipment.
