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.

Compact 24 V Power Supplies, 20 A and 40 A Units

The innovated 3-phase SITOP PSU300M power supply units provide a high degree of functionality and performance in just a small space. With a width of only 70 and 150 mm, the 20 A and 40 A stabilized power supply units are among the most compact in their performance class. A signaling contact for evaluating the operating status "24 V DC ok" has been integrated. The wide input range of 320 to 575 V, the high degree of efficiency up to 93% and a generous reserve capacity make it possible to use the unit for almost any application on power networks around the world.

Optocoupler Module for S7-300 Switches High Loads Faster

The new terminal block for the SIMATIC TOP connect modular system cabling can switch high 24 V DC loads up to 4 A with switching sequencies up to 500 Hz. The 8-channel optocoupler module adapts the output signals of the SIMATIC S7-300 to the power requirements of the I/O. The operating states of the short-circuit protected channels are visualized by red and green LEDs. If a fault occurs, a group fault signaling contact responds.

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.

SITOP und LOGO!Power Power Supplies, Catalog KT10.1 - 2008

The catalog for SITOP and LOGO!Power controlled power supplies (Order No. E86060-K2410-A101-A6-7600) has been updated. A PDF is available for English and German. Spanish, French and Italian versions will be available soon.
New features include:

Slimline SITOP smart universal power supply

Compact 3-phase SITOP modular 20 A basic model and

SITOP PSA 100E power supplies for straightforward requirements.

Compact 48V Power Supply SITOP

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.
