Delta Rolls Out the Ultron DPS High Performance UPS

The Mission Critical Infrastructure Solutions (MCIS) business unit of Delta Electronics announced the roll out of the Ultron DPS 160/200 kVA high performance uninterruptible power supply (UPS) series to Taiwan, China, and South East Asia. First introduced to Europe, Russia, South America, and India in 2011 this series is receiving customer acclaim in each market.

Delta’s Ultron DPS is a double-conversion and IGBT-rectifier three phase UPS. With a state-of-the-art triple level inverter (TLI) and three phase power factor correction (PFC) topology, the Ultron DPS features industry leading performance of up to 96 % AC-AC efficiency, input power factor > 0.99, output power factor of 0.9 and low iTHD < 3%. Aiming to achieve the highest availability possible, Delta’s Ultron DPS has special designs in the areas of battery management, fan speed control and ease of maintenance. With a smaller footprint, higher efficiency, and lower cost, the Delta Ultron DPS is also transformerless and designed to meet today’s market requirements. In addition, Delta offers an optional inbuilt isolated-transformer model for when galvanic isolation is needed by the application. Overall capacity expansion is up to 8 units (up to 1600 VA) without requiring extra hardware.

Dr. Charles Tsai, general manager of Delta MCIS, said, “The excellent power performance and high system availability of the Ultron DPS provides customers with the benefits of stable power supply, high power efficiency, low capital investment and low overall operational cost. In terms of size and footprint, we are proud to claim the Ultron DPS as the most compact UPS of its kind in the market.” .

“In Europe, Russia and India we’ve seen the Ultron DPS installed to protect a wide range of mission critical applications including telecom infrastructure, data centers, and in the manufacturing environment for paper, solar products, bearings, and more. We believe it will be also be highly acclaimed as a high performance UPS in the new markets,” said Dr. Tsai. “We expect to launch more models in the Ultron DPS series and will continue Delta’s engineering efforts in UPS development in response to global customer needs”.
