SITOP modular Basic Units, 24 V

The power supply for all requirements

Compact basic devices for 1, 2 or 3-phase connection and output current from 5 A to 40 A form the basis of the stabilized 24 V power supply. Add-on modules for extra functions are then added depending on the particular requirements. The robust metal housing is also well-equipped for use under rugged industrial conditions. The vibration-proof, DIN rail mounting is also made of metal. This makes installation fast, easy and vibration-proof too. All versions featuring a PCB coated with protective layer can also be used in high humidity, or in dusty or corrosive environments. The electronic design of the switches-mode power supplies also features reliability and quality. The wide input range and international certifications permit use on almost every power network around the world.
The 1-phase basic 5 A and 10 A units can even be connected to two phases thanks to the ultra-wide range input up to 550 V.

The 3-phase basic 20 A and 40 A units have been innovated and with a width of only 70 and 150 mm they are among the most compact units in their performance class. A signaling contact for evaluating the operating status has now been integrated and the input voltage range has been extended to 320 – 575 V. With an efficiency of up to 93% the stabilized SITOP PSU300M power supply units are extremely efficient and the heat generated in the control cabinet is correspondingly low. The extra power with 1.5 times rated current for 5 seconds enables loads with a high starting current to be switched on without any problems. .

Wide range of functions onboard.

A high level of functionality is already integrated in all the basic units. Three LEDs give you clear, detailed information on the current operating status. The output voltage can be increased by 20% with an easy-to-access potentiometer. This means that even with very long cables, all 24 Volts arrive at the devices. For handling short circuits, you can choose between switch-off with storage and constant current with automatic restart. Thank to its integrated power boost, SITOP is able to deliver up to three times the nominal current (e.g., for engine running or for intentionally blown fuses). If you have high continuous current requirements, use identical-type SITOP devices and switch to "parallel operation."

For flexible protection against a wide variety of risks, the basic SITOP modular devices can be combined with all SITOP add-on modules.
