Transistor Devices Inc. (TDI, Hackettstown, NJ) introduced its Mercury Series of power modules ac-dc rectifiers and front ends. The Mercury Series provide the benefits of reliable power in harsh utility environments, lower power dissipation, reduced cooling requirements, low profiles for scaleable solutions, and expanded power ranges in the same space. The series is suitable for distributed architectures and battery systems.
Although commercial grade in construction and cost, the power modules feature an extended, wide-range, ac-input of up to 300 Vac for limited durations; a high-power density to package 1,200 W to 2,400 W power levels in the same package, a high conversion efficiency of up to 91 percent; and a dual package design (1U and 2U). Mercury modules are designed for commercial applications and operation in a temperature environment of -20 °C to +55 °C. The modules will also turn on on -40 °C for warm-up. When used in higher ambient applications, the units should be derated at 10 percent/°C to a maximum of +65 °C operation.
