Power Supply Product：
600W Model Added to 200 - 425VDC Input DC-DC ConverterSeries (PH-A Series)
 Industry Smallest in its class with high power density and ultra-small dimensions (1/2 bricksize) Conducted cooling in a board mount type
 Compliance to EN62477-1 OVC III Safety Standards (overvoltage category III)

December 20, 2019
TDK Corporation announces the introduction of 600W model to the TDK-Lambda PH-A
series of DC-DC power modules with high voltage DC input. PH-A Series range now include
50, 75, 100, 300 and 600W outputs.600W model will be available for sales from January
2020 through TDK-Lambda Corporation.
PH600A280 designed with TDK’s original transformer configuration (patent pending),
optimized mechanism design, and achieved industry’s 1/2 brick size, smallest design in its
class (50% smaller than TDK’s current products). Power conversion efficiency is also
improved 2%. This will contribute to the miniaturization and energy saving at customer
devices.
Like the 300W models, 600W model has also been certified to meet the EN62477-1 Safety
Standards (overvoltage category III). This will be beneficial to the customer for obtaining
IEC60204-1 International Machine Safety Standards. By having PH600A280, Insulationtransformer may be removed from the distribution board. This will help customer devices besmaller, lighter and lower in total cost.
The customer can also design their external input e-cap bank to suit the required hold-up
time. This flexibility is good for hold-up time critical application such as Robot controllers andFactory Automation.
Main applications
Robot controllers, Factory Automation (FA), Telecommunication (ICT) equipment,
Semiconductor manufacturing equipment, etc.

Main features and benefits
 Ultra-small: Industry smallest in its class, 1/2 brick size with 600W output (50% smaller
compared to current products)
 Highly efficient: 93% (280 VDC input)
 Conducted cooling in a board mount type
 Safety standard certifications: UL/CSA/EN62368-1, EN62477-1 OVC III (overvoltagecategory III)
 Wide operating temperature range: -40 to +100°C (base plate temperature)
