SITOP DC/DC converters

SITOP DC/DC converters – for a stable power supply despite a fluctuating DC voltage

A SITOP DC/DC converter can be used as a “refresher” – in other words, this module guarantees a reliable power supply to a remote load when bridging long distances. At the same time, a SITOP DC/DC converter serves as a stabilizer: If the power supply is unstable, it stabilizes it in the downstream feeder. This type of module is ideal for use with battery-powered devices, where the battery’s output voltage can vary depending on its charge status. A SITOP DC/DC converter ensures a stable 24 V DC supply to connected loads, such as a control unit (CPU).

SITOP PSU3400

SITOP PSU3400 DC/DC converters ensure a stable 12 V or 24 V power supply despite a fluctuating input voltage.

Operation with 24 V DC or 48 V DC batteries, thanks to a wide input voltage range
Avoidance of incorrect installation, thanks to reverse polarity protection at the input
Small mounting surface and space savings, thanks to a slim design and the possibility of different mounting positions
Adjustable output voltage for compensating voltage drops
Signaling contact for easy integration into the plant monitoring system
Minimal heat dissipation inside the control cabinet, thanks to the power supply’s high degree of efficiency
Low energy consumption, thanks to the high degree of efficiency
Reduced energy losses even during no-load operation, thanks to very low no-load losses
Extensive certifications for all standard applications worldwide
Industry-specific use in shipbuilding (maritime applications), thanks to DNVGL and ABS Marine Approval

SITOP PSU400M

The SITOP PSU400M power supply with a 600 V DC input is suitable as an efficient DC/DC converter for drive and battery systems. It has a large input range and temperature range, high efficiency of 95 percent, and a slim design. Thanks to its overload capacity, it supplies 50 percent extra power for 5 s/min.

As an accessory, a voltage surge limiter is available as ballast for the SITOP PSU400M. This makes it possible to connect the DC/DC converter directly to a DC voltage of up to 900 V DC.

DC/DC converters Plants and systems with safety-related applications are equipped with a battery backup. These include, for example, applications in industry, power plants, water treatment plants, and vehicle on-board power supplies. In order to reliably supply the loads involved in this type of application with their rated input voltage, SITOP offers a range of different DC/DC converters.

Stable power supply despite fluctuating DC voltage

Typical DC/DC converter applications:

Refreshing DC voltage when bridging long distances
Stabilizing DC voltage when the input voltage fluctuates
Galvanic isolation of DC feeders, e.g. in shipbuilding
Use as battery-powered backup supply for infrastructure facilities, e.g. at train stations, for maximum availability
Stable power supply for battery-powered AMR (autonomous mobile robot)
