This blog article discusses the solutions from American ZETTLER that are capable of switching or isolating high voltage circuits operating at 480VAC. This ranges from bulky definite-purpose contactors, which handle the higher power loads more commonly associated with 480VAC circuits, down to miniature power (latching) relays popular in lighting.
These robust switches offer safety approvals and certified ratings well suited for a number of applications including refrigeration, air conditioning, heating, elevators, food service equipment, cranes, hoists, welding machines, power supplies, vending machines, lighting, pumps and compressors.
Perspective: A smaller XMC0 contactor next to AZSR1200, AZSR190, AZ2800, and AZ576 power relays.
25-90 FLA up to 600VAC
125-450 LRA at 480VAC
Make/break 40A, carry up to 200A, 920VAC (85°C)
50 make/break cycles up to 200A, 920VAC (85°)

When an AC-DC power supply’s input voltage is interrupted the DC output will only remain within regulation for a short period of time. This is specified on the power supply datasheet as the hold-up time. During this hold-up time the power supply relies on energy stored in its capacitors to maintain operation.
Hold-up time is important in certain vertical markets. The medical industry’s concern regarding hold-up time has increased since the release of the EN 60601-1-2; 2015 (Ed4) immunity standard. Primarily created to address the growing number of products used in home healthcare, this standard specifies multiple AC voltage dips ranging from 20 msec to 5 seconds. The longer outages are addressed by batteries or by designs that ensure no harm will occur to the patient or operator if the power supply output voltage drops out of the regulation band.
Airborne equipment is covered by the DO-160 standard. Section 16 of the standard refers to power input, simulating conditions of aircraft power from before engine start (using auxiliary ground based power) to after landing, including emergencies. The requirement is for a hold-up time of at least 200 msec.
In a recent article on their Power Supply Blog, TDK Lambda explores power supply hold-up time: What it is, where it’s important and, most importantly, several technical approaches for extending hold-up time. You can read that article here.

Virtium recently expanded their StorFly® line of industrial-grade SSD’s, boosting storage capacity in drives that protect critical data in embedded systems. The Virtium StorFly line features industrial temperature (I-Temp) SSD’s with continuous operation in temperatures from -40C to 85C.
SSD capacity for embedded-industrial applications follows a different principle than storage for enterprise and consumer applications. StorFly drives are designed to provide secure data storage optimal for demanding applications such as data logging and high-definition video and audio. These applications require a balance between the maximum allowable capacity and drive integrity that can be compromised by heat and other adverse conditions. The StorFly line with I-Temp now includes SSD’s with up to four terabytes (TB) of capacity:
- 1TB M.2 SATA
- 2TB M.2 NVMe
- 4TB 2.5-inch SATA
Read the entire press release about these higher density solutions here.

Power supply Technical Center certified to ISO 13485 – the first ever in Japan
Press Release July 20, 2020
TDK Corporation (TSE 6762) is pleased to announce that TDK-Lambda Japan received ISO 13485:2016 Medical Devices – Quality Management System – certification for the TDK-Lambda Nagaoka Technical Center (Nagaoka City, Niigata Prefecture, Japan). This is the first time a standard switching power supply manufacturer in Japan has received ISO 13485 certification and brings the group total to five locations. The scope of this latest registration covers the Design/Development, Manufacturing and Servicing Activities (Analysis, Repair and Overhaul for Field Returns) of Components (Switching Power Supply) for Active Medical Devices. Now, five of TDK-Lambda’s major development, design and production sites in Japan, the United Kingdom, the United States of America, China, and Malaysia have been certified. This enhances the Group’s capability to provide products and services to the global medical device market.
TDK-Lambda has focused on the medical device market, developing a large portfolio of medically certified products to the international IEC 60601-1 standard. Adopting ISO 13485 provides a practical foundation for manufacturers to address the Medical Device Directives, regulations and responsibilities. It demonstrates a commitment to the safety and quality of medical devices.
