We offer standard products: high-density designs, complete brick family: 1/8, 1/4, 1/2, and full brick. Features include 2:1 and 4:1 input ranges, high efficiencies up to 93 percent, with single and multiple outputs. Additional options include remote on/off, continuous short circuit protection, remote sense, external trim, and synch options.

AC-to-DC Power Supplies
With power ranges from 1 watt to 3 kilowatts (kW) and beyond, these high-reliability power supplies are available in open card, cased, and in some series, encapsulated. Features include universal input, soft start, single and multiple outputs. All open card and cased switchers are agency approved.

Custom Projects

Medical Device Power Supply
This medical device application required a low-cost, medical-grade power supply to for C-PAP machines. The client specifications required an especially cost conscious power supply and off-shore supply chain support. Wall Industries worked with one of its offshore partners to modify an existing medical grade power supply to meet the application’s derating guidelines and performance screening tests. Wall’s design expertise and off-shore relationships met the client’s design and cost requirements within the project’s timeline.

Medical Device Power Converter
This military-grade, power converter for a medical device required a power converter to charge the battery in a defibrillator from either a ground vehicle or aircraft Wall Industries engineering team worked with the customer to create a wide input range military and medical grade (EN60601-1 3rd edition) DC-DC converter that met all specifications required. This meant both commercial and military EMI, shock and vibration as well as safety.

Medical Device Uninterrupted Power Supply
Wall Industries worked with a leading design and manufacturer for remote surgical robots to create a power supply that would not only power the robot but act as a UPS allowing fault-free operation even in a power outage. This design was Microchip-based and met EN60601-1 3rd edition standards. The surgical robot’s uninterrupted power supply’s monitoring capabilities enabled keeping its batteries charged while in operating mode, as well as a smooth transition of power in case of a plug disconnect or power outage.
