SITOP compact is a single-phase 12-volt and 24-volt power supply with an extremely slim design that saves space in switchboxes and small control cabinets. This design is ideal for distributed solutions. SITOP compact power supply enclosure widths range from just 22.5 mm to 52.5 mm. The compact design not only saves space, but also energy and high efficiency over the entire load range. This feature makes the SITOP compact power supplies an excellent solution for powering devices that are often in standby mode, as the power losses are extremely low during no-load operation. The Siemens SITOP PSU100C Siemens SITOP compact 24V product line can also be combined with DC UPSs as well as selectivity or redundancy modules. To facilitate the electrical connection, SITOP Compact power supplies have a wide range of AC and DC inputs in the form of plug-in terminals for simple electrical connection. Another advantage of these power supplies is their ability to operate in a wide temperature range.

SITOP compact power supplies (SITOP PSU100C) are stabilized power supplies that are characterized by:

• 1-phase wide range inputs 85 V to 264 V AC or 110 V to 300 V DC
• for 24 V DC /3.7 A version for NEC Class 2 electrical circuits with limited output current (100 VA)
• small installation area due to slim design
• energy savings of up to 28% compared to similar units
• up to 53% energy savings when devices are idle or in standby mode
• adjustable output voltage to compensate for voltage drops (starting from 1.3 A)
• Green LED for "24 V OK" and "12 V OK".
• working temperature range from -20°C to +70°C
• plug-in connection terminals for prefabricated cabling and high-speed electrical connection
• comprehensive certificates such as UL, ATEX or DNV GL

In our offer you will find the full assortment of the SITOP compact series, which can be searched in the shop according to standard Siemens reference numbers 6EP1322-5BA10 or 6EP13225BA10. Below we present the catalogue numbers under which you should look for SITOP compact power supplies in our service. As previously mentioned in the text, single-phase SITOP PSU100C power supplies are available in 12 VDC and 24 VDC versions. In the first one there are two power supplies Siemens 6EP1321-5BA00 and Siemens 6EP1322-5BA10. SITOP 6EP1321-5BA00 stabilized power supply is a version with parameters:

- 12 V DC/2 A
- Stabilized power supply
- Input: 100 … 230 V AC (110 … 300 V DC)
- Output: 12 V DC/2 A

In turn, the SITOP 6EP1322-5BA10 power supply is distinguished by the following specifications:

- 12 V DC/6.5 A
- Stabilized power supply
- Input: 100 … 230 V AC (110 … 300 V DC)
- Output: 12 V DC/6.5 A

This group is complemented by an accessory in the form of a removable spring terminal, also available in our shop under code Siemens 6EP1971-5BA00.

The SITOP compact 24 VDC power supplies group is more extensive in terms of the choice of versions for the nominal current value, with a choice of 0.6 A, 1.3 A, 2.5 A, 3.7 A and 4 A. The stabilised 24 VDC SITOP compact power supplies are available on our website under the following reference numbers:

- Siemens 6EP1331-5BA00 – 0.6 A
- Siemens 6EP1331-5BA10 – 1.3 A
- Siemens 6EP1332-5BA00 – 2.5 A
- Siemens 6EP1332-5BA20 – 3.7 A
- Siemens 6EP1332-5BA10 – 4 A

Additionally, the SITOP 6EP1332-5BA20 model has limited output power according to NEC Class 2.For these models Siemens dedicates a wide range of selectivity modules and two models of redundant modules. The range of Siemens redundant modules is presented below:

- Siemens 6EP1962-2BA00: SITOP PSE202U redundancy module, Input/output: 24 V DC/NEC Class 2 suitable for decoupling two SITOP power supplies output power limited < 100 VA
- Siemens 6EP1964-2BA00: SITOP PSE202U redundancy module, Input/output: 24 V DC/10 A suitable for decoupling two SITOP power supplies, with a maximum of 5 A output current

The selectivity modules, in turn, are the following reference numbers and parameters:

- Siemens 6EP1961-2BA11: SITOP PSE200U 3 A selectivity module, 4-channel selectivity module, input 24 V DC, output 24 V DC/3 A per channel, adjustable response threshold 0.5 … 3 A, with common alarm signal
- Siemens 6EP1961-2BA31: SITOP PSE200U 3 A selectivity module, 4-channel selectivity module, input 24 V DC, output 24 V DC/3 A per channel, adjustable response threshold 0.5 … 3 A, with single-channel signaling
- Siemens 6EP1961-2BA51: SITOP PSE200U 3 A NEC Class 2 selectivity module, 4-channel selectivity module, input 24 V DC, output: 24 V DC/3 A per channel, adjustable response threshold 0.5 … 3 A, with common alarm signal
- Siemens 6EP1961-2BA61: SITOP PSE200U 3 A NEC Class 2 selectivity module, 4-channel selectivity module, input 24 V DC, output: 24 V DC/3 A per channel, adjustable response threshold 0.5 … 3 A, with single-channel signaling

The product range for the SITOP compact 24 VDC, like for 12 VDC power supplies, is complemented by the Siemens 6EP1971-5BA00 spring terminal block.
