Called the RACPRO1 range, it includes five parts: 240W (24Vout), 480W (24 or 48Vout) or 960W (24 or 48Vout), which are 43mm, 52mm or 80mm wide respectively.

24V nominal outputs can be adjusted across 24 to 28Vdc, while 48V types can be adjusted across 48 to 56Vdc.
“The design teams have achieved outstanding electrical efficiency with advanced thermal management, thus not requiring spacing on each side of the parts for cooling,” said the company. It “enables operation at full power up to +60°C with only convection cooling, and down to -40°C”.
That efficiency amongst the models peaks at 94 to 97% depending on the version. No-load consumption is 1W (240W) or 3W (480W or 960W).
All versions can continuously deliver +20% more power if ambient temperature is always kept below +45°C, and the outputs can support 50% over-load for 5s to support capacitive or other high-inrush loads.

Inputs are 320 – 575Vac three-phase, or 430 – 850Vdc.
For two-phase operation, the 240W part (RACPRO1-T240) will operate at full-power from 350 to 575Vac, while the other two have two-phase restrictions: only 350 to 480Vac, and 340W maximum load for the two RACPRO1-T480 variants, or 600W for the two RACPRO1-T960 versions.
Power factor in 480W and 960W models is >0.9 “thanks to innovative circuit topology, although, in contrast to conventional designs, a separate PFC stage has been dispensed”, said the company.
For ruggedness, 6kV surges can be withstood at the input, and -35V at the output for inductive loads.
Active in-rush current limiting is implemented, as is under-voltage lock-out.
Predicted lifespan is >80,000 hours at full load and 40°C ambient air.
480 and 960W versions have an LED display that indicates approximate load power in real time, and these also have DIP switches to set them into one of three modes: ‘standard’ (150% power boost), battery charging (constant voltage/current) mode or ‘parallel’ (passive load sharing).
Certifications include IEC/EN/UL 62368-1, IEC/EN/UL/CSA 61010-1 and IEC/EN/UL 61010-2-201 for safety.
EMC compliance is to EN 61000-6-4 Class B and EN61000-6-2 for emissions and immunity.
Manufacturing is in Europe.
Both wiring and DIN rail mounting are tool-less.
