Switchmode Rectifier suits telecom power systems.

Press Release Summary:

Providing 220 A @ 92% efficiency and less than 5% total harmonic distortion on ac input, GALAXY(TM) 595LT(TM) Rectifiers convert ac input voltage into dc voltage level required to power end-user equipment. Parallel operation with digital load sharing evenly balances load current among multiple rectifiers. Other features include intelligent fan-speed control, overvoltage and overcurrent protection, and digital meter for current, temperature, or rectifier alarm messages.

Tyco Electronics Increases Power Density by 120 Percent with New Rectifier for Large Telecom Power Systems

DALLAS, Texas - JUNE 21, 2004 - Tyco Electronics Power Systems, a leading worldwide supplier of telecommunications power equipment, today expanded its GALAXY(tm) 595 Series of switchmode rectifiers - a key element in the Tyco Electronics' GALAXY Power System 4848/100(tm) Battery Plant - with the 595LT(tm) Series Switchmode Rectifier. The 595LT Rectifiers integrate the latest switchmode technology with superior power, protection, and control features in a compact, cost-efficient power conversion system. The 595LT Rectifiers provide 220A at 92 percent efficiency and less than five percent total harmonic distortion (THD) on the AC input. The 595LT Rectifiers occupy half the space of and deliver 10 percent more power than previous 595 Rectifiers.

Spares provisioning is simplified by the full backward compatibility of the 595LT Rectifier. They replace Tyco Electronics' current 595 Rectifiers without needing any adapters, also eliminating the need to maintain spares inventories of both versions.

The new 595LT Rectifiers convert AC input voltage into the DC voltage level required to power end-user equipment, providing the highest quality DC power for telecommunications and data processing systems. Tyco Electronics' revolutionary rectifier technology packs more power per cubic inch, weighs substantially less, requires minimal maintenance and frees up valuable floor space.

"The 595LT Rectifier's reliable high performance and simple installation meets the needs of the most stringent telecommunication and data processing applications, thus furthering Tyco Electronics' commitment to superior and reliable telecommunications power solutions," said Sabi Varma, vice president of marketing and business operations at Tyco Electronics Power Systems.

The 595LT Rectifiers feature parallel operation with digital load sharing, which evenly balances the load current among multiple rectifiers. The rectifier also provides precise regulation required to maximize battery life and can be used to form or recondition batteries.

Functionally, the first conversion stage incorporates a new, high-efficiency topology providing optimum power usage and enabling direct conversion of voltages up to 480 Vac nominal. The output voltage is adjustable to 58 Vdc for equalizing battery strings or for initially charging battery strings.

The 595LT Rectifier's simplified control and monitoring includes a digital meter indicating current, temperature, or rectifier alarm messages for convenient status readout. An intelligent fan-speed control maintains safe operation at ambient temperatures from 32 °F to 122 °F (0 °C to 50 °C) and minimizes acoustic noise. To prevent load or rectifier damage, the 595LT Series is equipped with two levels of both overvoltage and overcurrent protection.

The 595LT Rectifier is immediately available with a list price of $6,900.
