The one, two and three-phase SITOP modular power

supply units are the technology power supplies for

demanding solutions. They offer maximum functionality

and reliability for use in complex plants and machines.

The wide-range input allows connection to almost any

electrical power system worldwide and ensures a high

degree of safety even if there are large voltage

fluctuations.

These high-performance power supply units offer out-

standing overload characteristics: Power Boost delivers up

to three-times the rated current for short periods of time in

order to trigger protective equipment, and with 50% Extra

Power, loads with high inrush current can be connected

without any problems. In case of overload, you can choose

between constant current or latching shutdown.

The extremely high degree of efficiency ensures low

energy consumption and minimal heat loss in the control

cabinet.

The compact metal enclosure, which requires no spacing

at either side, also saves space on the DIN rail. To further

increase availability, SITOP modular power supply units

can be combined with buffer, DC UPS, redundancy and

selectivity modules.

High functionality for every application

SITOP modular offers special functions that facilitate

universal use and flexible adaptation to the application:

Protection of overvoltages caused by

consumers

When connecting inductances such as DC

motors or contactors, voltages in excess of the

rated voltage can be created. During this period, the 24 V

power supply units enter the standby mode, after which

they then supply the set voltage again. This ensures that

the application is continuously supplied.

Parallel connection for performance

enhancement

For the parallel connection of 2 or more power

supply units of the same type, each be set to

“soft characteristics”. This ensures a symmetrical load dis-

tribution that prevents one power supply being subjected

to an unevenly high load and thus its service life being

reduced.

In the individual mode the "hard characteristic" (delivery

status) ensures a constant output voltage, regardless of

the output current.

Adjustable overload response

In the constant current mode (delivery status)

the output current is limited to 1.15 times the

rated current. With a larger load, the output

voltage is reduced to just a few volts.

The constant current also permits the dimensioning of the

cables according to this maximum current.

If the 24 V output should become de-energized,

the latching shutdown operating mode is the

correct choice. The power supply shuts down if

overloaded by 1.15 times the rated current.

To restart, a targeted activation of the power supply is

necessary, e.g. by means of the Remote On/Off function.
