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.
