TDK Lambda has recently released the compact CUS400M series of single-output AC/DC power supplies. The supplies offer either 12V or 24V DC output with 15V, 19V, 28V, 36V and 48V versions to follow. The CUS400M is packaged in the industry standard 3″ x 5″ footprint and can deliver 400W with forced air cooling.
The CUS400M can be used in both Class I and Class II (no earth wire) applications and offers efficiencies of up to 94%.
An option board providing a 5V 2A or 12V 1A standby voltage, remote on/off, remote sense, DC OK signal and AC fail signal is also available.
Mechanical options include metal base plate, U channel, cover and top mounted integral fan.
Safety certifications include IEC/EN/ES 60601-1 and IEC/EN/UL 62368-1 with CE marking for the Low Voltage, EMC and RoHS Directives. The units comply with EN 55011-B and EN 55032-B conducted and radiated emissions and meet the EN 61000-3-2 harmonics, IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
Typical applications include medical (B and BF type), home healthcare, dental, test and measurement, broadcast, professional audio and industrial equipment.

The AC power supplied to and used by household and commercial buildings in the USA is primarily 120VAC. This voltage is suitable for most electrical and electronic equipment in the home or office, but for the higher power requirements of electric driers, air conditioning and electric ovens, 208VAC or 240VAC is also available.
In larger industrial properties, in addition to 208VAC and 120VAC, 480VAC three-phase is supplied to the building in a “WYE” (or Y) configuration. Using 480VAC three-phase to power larger electrical equipment like fork lift battery chargers and heavy machinery allows less current to be drawn by the load, thus enabling the use of lighter gauge wire. In addition, the current is balanced equally in each phase. This power disctribution scheme improves power distribution efficiency.
This blog article from TDK Lambda delves further into this topic, explaining how 277VAC comes about and how it’s used in industrial applications. The article also highlights a few of TDK Lambda’s power supply solutions that are well-suited for use in 277VAC input applications. You can read the entire blog post here: Where and why is a 277VAC input used in the USA?

New Product Release from JAE
MX80 Compact Waterproof Automotive Connectors
In response to the growing demand for miniaturized in-vehicle connectors, JAE has released its MX80 series of compact automotive in-line connectors. Featuring a 2.54mm pitch, this series is ideal for use in areas where space is limited. In addition to their small size, these connectors deliver the highest quality performance in terms of power handling, contact reliability and vibration resistance. And they come with Terminal Position Assurance (TPA) functionality.
A brief overview of the series’ specifications is shown below:
*2 and 4 position options, and 0.13 to 0.22mm2 cable options are available as prototypes, with mass production starting soon.

The series offers an input range of 9V to 53Vdc and adjustable outputs from 9.6V to 48V. Special care was taken in the design of the i7C to ensure a seamless transition from buck to boost operation.
With efficiencies of up to 97%, power losses are minimized allowing the product to operate and deliver high output power in demanding thermal environments. Under light load conditions, the i7C’s control techniques significantly reduce power dissipation. A 5mA input current draw is typical under zero load conditions. And the input current can be further reduced to 0.25mA (typ) when the remote on-off is utilized. This extends the amount of time battery powered equipment can remain functional during periods of non-peak operation.
