RS Components is now stocking the Siemens compact 40 A base unit which is part of the SITOP modular power supply series. With new innovations and at only 150 mm wide and 125 mm deep, the PSU300M allows for highly compact tests. The 20 A power supply was also reviewed and is only 70 mm wide.
The two SITOP PSU300M standard mounting rail power supplies, for connection to three-phase 400-500 V a.c. networks, now have a wider range input (from 320 to 575 V a.c.) than previous versions. This enables them to be used in almost all of the world’s three-phase networks, and they provide a reliable 24 V supply even when there are large deviations in the voltage supply.
The user can simply evaluate the ‘DC 24 V OK’ operating mode via the new, integrated dry signalling contact. Apart from its small dimensions, the power unit now supplies 60 A for five seconds, so it can easily switch on even terminal equipment with high starting currents. Its efficiency of up to 92% reduces energy consumption and heat build-up in the control cabinet.
Like all SITOP basic units in the modular series, the new SITOP PSU300M power supplies also have rugged metal enclosures. They can provide up to three times the rated current to meet short-term peak power demands. Moreover, the short circuit response can be set: latching shutdown or constant current with automatic re-ramp up to the output voltage.
Used in combination with SITOP add-on modules, comprehensive protection can be achieved against primary and secondary disturbances. Additional benefits include an LED output indicator, fully regulated output and switchable output characteristic for parallel operation.
