SITOP modular 24 VDC: The first 24 VDC power supplies in modular design
The new generation of SITOP power supplies features an innovative modular concept. Basic 24 VDC units are available for single and 3-phase applications from 5 A up to 40 A, covering most networks worldwide. The modular design allows adding extra functionality to the basic unit. As needed, signaling, back-up, redundancy, DC UPS, and an electronic diagnosis module can easily be added. All this flexibility comes at a surprisingly low price, making SITOP Modular the perfect choice for 24 VDC industrial power installations. |  |

The basic unit With compact, primary switching power supplies installation is fast and easy: The robust metal design with its vibration-resistant, DIN rail mounting is ideal for use under rugged industrial conditions. A wide range of input voltages and international agency approvals qualify SITOP Modular for use in almost every network worldwide. Specifically, the 5A and 10A units cover single and three-phase voltages in one unit: hot wire and ground are used for single phase applications, whereas only two hot wires are needed for three-phase networks. |  |
Footprint has become the most important purchasing criteria for automation and controls components due to demand for smaller panels. The new SITOP Modular 3-phase 24VDC/20A power supply addresses this issue with a substantial reduction of the width from 160mm with the previous basic 3-phase unit to 70mm with the new 3-phase unit. |  |
The basic unit offers functions, already covering many requirements:
Robust metal construction of IP 20 housing and DIN rail clip
Compact footprint is among the smallest in the industry
Wide input voltage ranges from 85 to 132 VAC and from 176 to 550 VAC (5 A and 10 A units only)
Power boost up to 300% and 25 ms to serve high inrush loads
Load sharing with parallel operation
Three LEDs provide clear, detailed information on the current operating status
Adjustable output voltage up to +20% via front mounted potentiometer prevents voltage drop in long cable runs
Manual reset, or automatic restart option to handle short-circuits.
