Power Distribution

Throughout the sector of plant engineering and machine construction, a safe and reliable power supply is necessary for supplying the process with energy. Requirements are extremely diverse and this is reflected in our product range.
Maintenance-free, Uninterruptible DC Power Supply w/o Battery Replacement
SITOP SV - maintenance-free DC-UPS without battery replacement
The new SITOP UPS500S uninterruptible power supply is based on an energy storage comprising powerful capacitors. These have a long service life even at 60 °C, unlike conventional lead batteries that have to be replaced annually at 40 °C. Elaborate ventilation is no longer necessary as the capacitors do not emit any hydrogen. The short charging times ensure high availability after power failure.

Compact 48V Power Supply SITOP
SITOP smart 48 V / 10 A
Loads requiring a 48VDC input voltage instead of the usual 24VDC supply can now use the 3-phase SITOP smart power supply with 10 A output current. With a width of only 70 mm, the compact 48V power supply takes up just a little space on the rail. The primary-pulsed power pack has a wide-range input and an efficiency of 93%. For problem-free connection of loads with high inrush current, it provides 50% extra power for up to 5 seconds.

New Slimline SITOP Modular 20 A Power Supply
SITOP modular 20A
The 3-phase SITOP modular with 20 A output current is now available in a 70 mm wide design. The innovated 24V power supply belongs to the slimmest and most compact in its performance class. The DIN rail mounting device features more than 93 % efficiency and an additional function of 50 % more rated current for 5 seconds. The additional extra power facilitates problem-free connection of loads with high inrush current such as DC/DC transformers and motors.
SITOP select - Sequential Activation of 24 V Loads
The SITOP select diagnosis module makes it possible to switch 24 V loads sequentially. Particularly for loads requiring a high power-on current, this leads to off-loading of the power supply, which can result in a reduction in the design size. The delay times of the 4 outputs can be set to 0 ms, 25 ms or 100 ms. SITOP select monitors the 24 V outputs for overload and short circuits and can switch them off selectively while continuing to hold the supply for intact loads. Downtimes are thus minimized and uptimes increased.
