Transformer rectifier maintenance service
Powerstax is now able to offer an indispensable service to those in possession of transformer rectifier units. Delivering large quantities of regulated DC power in industrial applications, 24/7 availability is often mandatory for these high value items. It is therefore important that every effort is made to keep them running smoothly in the long term with no interruptions or loss in functional integrity.
90W AC/DC desktop power supply in ultra-slim package
Providing up to 90W of power, the PEAD90SLF series of single output AC/DC desktop switching power supplies have been introduced by Power Partners. The standard input voltage range of 90-264V AC (47-63Hz) converts to output voltages of 12, 18, 19 and 24V DC that require no minimum load for operation.
PMICs target RF agile radio and FPGA applications
Designed as an integrated power solution for picocell and femtocell base stations, portable and handheld devices requiring a compact and integrated power solution, the ADP505x PMICs from Analog Devices target compact, high density power solutions for RF agile radio and FPGA/processor-based applications.
