Wide Operating Temperature and Power Boost Features

An extended surge strength of up to 6 kV at the input and an increased reverse voltage strength of greater than 35 V at the output, in conjunction with an extended temperature range of -40 °C to +70 °C, enable use in harsh industrial environments as well as in outdoor applications in the renewable energies sector. The RACPRO1-T480 and -T960 series achieve a power factor of greater than 0.9 thanks to innovative circuit topology, although, in contrast to conventional designs, a separate PFC stage has been dispensed with. Active inrush current limiting allows external circuit breakers to be dimensioned more precisely and their current load to be reduced upon switch-on.

High efficiency allows high packing density

The RACPRO1-T power supplies are characterized by an outstanding efficiency of up to 97.1 percent, which allows for a very high packing density with an extremely slim design of only 43 mm (-T240), 52 mm (-T480), and 80 mm (-T960). The devices can be mounted directly on the DIN rail without additional spacing between them, which means that the remaining space can be fully utilized for other components. The low power dissipation and the optimized thermal PCB design achieve an exceptional lifespan of over 80,000 hours at full load and an ambient temperature of 40 °C. The operating temperature of the RACPRO1 power supplies ranges from -40 °C to +70 °C at full power output up to 60 °C and a power boost of 150 percent for 5 seconds to start up against high capacitive and inductive loads.

With a thermal power bonus of 120 percent at 45 °C, the user may be able to do without an additional power supply if their system is not operated permanently in the higher temperature range.

LED load indicator

The RACPRO1-T480 and -T960 have an LED load display that shows the actual energy output in real-time mode. A separate switch allows the user to switch between standard mode with 150 percent power boost, battery charging mode with constant current characteristics, and parallel operation with passive load sharing without additional equalization lines. The system’s energy consumption remains minimal during standby mode or maintenance work, thanks to its low no-load power consumption ranging from 1 W (-T240) to 3 W (-T480 and -T960). ▪ ds
