TDK Lambda - SMPS UPS Power Supply Specialist

"Switching power supplies are power supplies switched by high-speed semiconductor switches. They are the most common type of compact, lightweight, high-efficiency power supply. Uninterruptible power systems (UPS) are backup power supplies that use a built-in battery to stably supply continuous clean power to connected devices when the regular supply power shuts down due to a power failure or other power problem. TDK-Lambda offers both these types of power supplies".
