It pays to understand a few important electrical parameters that can dictate the kind of applications specific power supplies can handle. Florian Haas | Traco Power Group A few basic factors go into the selection of low-voltage dc/dc and ac/dc power supplies for OEM use. At the risk of stating the obvious, the key objective […]
Switchers say bye-bye to EMI
Electromagnetic interference can emanate from high di/dt loops found in some switch-mode supply topologies. New controllers overcome these difficulties by integrating key components inside the chip package. Tony Armstrong | Power by Linear, Analog Devices Inc. It goes without saying that PCB layout sets functional, electromagnetic interference (EMI) and thermal behavior of every power supply […]
Power operating limits: How to choose the right power supply
Not all power supplies react to over and under-voltages and currents in the same way. It pays to know the tradeoffs of different approaches to protection. Ron Stull | CUI Inc. Power supplies can experience operating conditions outside normal specified limits, such as input under- or over-voltage, or variations in load and ambient temperature. These […]
AC, DC power sources provide single and three-phase outputs up to 6,000 VA
The Asterion 4503 supplies AC and DC output power up to 4,500 VA or 4,500 W, and the Asterion 6003 supplies up to 6,000 VA or 6,000 W. Both units come in a 4U chassis and can supply single- or three-phase output power. Like the lower-power 1U and 2U models, Asterion Models 4503 and 6003 […]
Linear vs. switching power supplies: Not always an easy choice
There are some uses that demand the low noise and fast response only available through traditional linear supplies. ALEX KARAPETIAN | ACOPIAN TECHNICAL CO. ASK almost any engineer about linear power supplies and the likely instinctive reaction will be, “Sorry, I can’t use them — they’re too inefficient.” Any possibility of using a linear supply […]
Tiny, low profile, 150-W AC-DC supply carries medical, IT approvals
XP Power has announced its EPL150 series, a range of high density, low profile, open-frame AC-DC power supplies aimed at space-critical, cost-sensitive, industrial, ITE and healthcare applications. The EPL150 series produces 100W output with convection cooling and 150W with as little as 10CFM airflow. The product has a 2” x 4” footprint and its low […]
