Power modules
 Lambda Americas Inc., San Diego, Calif. The PFE500F power module has more features than its predecessors, including active current-share and remote on/off. Like the existing models, the new PFE500F versions provide a convenient AC-DC board-mounted solution with an output power of up to 504 watts for applications in industrial, datacom and telecom equipment. The active current-share feature enables up to six PFE500F modules to be paralleled together to accommodate increased power requirements and/or redundancy. In addition, the positive logic remote on/off control and inverter-operation-good functions provide greater flexibility in the start-up or shutdown sequencing and diagnostics of the power system. An auxiliary output of 10-14 V at 20mA is included in the modules for powering external circuits. The power module comes in 12 V, 28 V, and 48 V nominal outputs. The 12V PFE500F delivers up to 504 W with a maximum base-plate temperature of 85°C, while the 28 V and 48 V models deliver the same output at temperatures up to 100°C.

Noise dosimeters
Scantek Inc., Columbia, Md. A pair of noise dosimeters from CESVA, the DC-112a and DC-112k, both comply with the American standard ANSI S1.25-1991 class 2 and enable the health and safety protection measures of workers against risks arising from exposure to noise, evaluated according to OSHA and other agencies. Both instruments allow the use of frequency weightings (A or C), time weighting (F or S), exchange rates (3, 4, 5, or 6), and measure simultaneously using two programmable threshold levels, which means that only one measurement is needed for norms requiring a double threshold. These dosimeters have a high storage capacity with 64 MB, which enables the time history of the measurement to be stored.
