The SPR10-T is a solid state remote power controller and is suitable for DC 12 V and DC 24 V applications. A special feature of the SPR10-T is that it combines switching and protecting functions in a single device. In addition, it offers status indication by means of LED and status output.

Reliable Switching Operation with Overcurrent Portection

Unlike conventional electronic and mechanical relays, the SPR10-T provides integral overcurrent protection. An additional external overcurrent protection element is not required. In the event of a failure, only the faulty path is disconnected and the fault is indicated at the device or at the status output; all other circuits remain unaffected. This ensures quick and easy trouble-shooting and increases machine uptime and system availability.

Four Functions In One Unit

• solid state relay with control input (ON delay 1.5 ms)
• electronic overcurrent protection (trip at 1.3 x IN)
• status signalling (by means of LED and status output)
• integral power distribution (by means of busbars)

For Powerful Loads

Direct mounting on symmetrical rails allows fast and flexible installation. In addition, several devices can very easily be connected by means of busbars, reducing wiring time to a minimum.

With current ratings of 20A and 25A, the SPR10-T is particularly suitable for powerful loads with a high current demand and a cable cross sections up to 10mm².

The combination of these properties is, with a width of only 12.5 mm, an efficient and compact solution for your application. You do not only save components, storage costs and space in the control cabinet, but you also significantly reduce planning and wiring efforts.

Technical Data

• Voltage rating DC 12 V/DC 24 V
• Operating voltage DC 9…32 V
• Number of poles 1-pole
• Signal outputs DC 24 V / max. 0,2 A
• Status indication 1 LED, green/orange/red

IEC C14 Appliance Inlet with High-Performance Filter

• Very High Attenuation
• Compact DSesign
• Metal Flange for Optimal Shielding
• V-Lock Cord Retaining

For applications that require particularly high interference immunity, Schurter is launching the new high-performance filters of the 5124 series. With identical dimensions to the proven 5120 and 5123 series, both symmetrical and asymmetrical interference signals can be attenuated even better with the 5124 series, thanks to the use of high-performance components.

The 5124 series combines an IEC C14 appliance inlet with a high-performance mains filter. Thanks to a wide metal flange, the housing makes contact over a large area, which guarantees an optimal filter and shielding effect.

High-Performance Filter:
The exclusive chokes with high-permeable toroidal cores of the 5124 series have an inductance that is many times higher than that of the standard 5120 series. This results in an attenuation of asymmetrical interference signals that is around 10 dB higher. Massively enlarged X-capacitors help gainst symmetrical interference. Despite significantly larger components, the dimensions of the 5124 predecessor’s series have been retained.

Identical Dimensions
The 5124 series is available in standard or medical versions. It makes sense to use it where a particularly high attenuation is necessary and the filter effect of a 5120 or even 5123 series is no longer sufficient. Thanks to identical dimensions, the optimal series can be selected - depending on the interference level - without any design changes. The appliance filters are, of course, equipped with the well-proven V-Lock cord retention system.

Performance and Approvals
The 5124 series is certified for currents up to 10 A/250 VAC according to IEC and 15 A according to UL/CSA at 125/250 VAC. It features ENEC, CQC as well as cURus approvals.

Data centers are handling and analyzing enormous amounts of information daily. As data generation increases, the heat generated by the data center indispensably increases. This excess heat generated by data centers can harm the hardware including Central Processing Unit (CPUs) and Graphic Processing Unit (GPUs), reducing their performances, or causing complete failures. To ensure optimal operation, it is crucial to select the right cooling solution.

Market Trends:
According to the (Technavio report 2023), the global market for cooling data centers is projected to increase from USD9.5 billion in 2020 to USD22.6 billion by 2025, with a Compound Annual Growth Rate (CAGR) of 18.0%. However, the high energy consumption associated with data center cooling contributes to increased carbon emissions and energy costs. Therefore, businesses are seeking eco-friendly and energy-efficient cooling technologies, such as free cooling, liquid cooling, and artificial intelligence (AI).

Free Cooling:
One of the most popular methods for cooling data centers is free cooling, which utilizes outer air to cool the center, as opposed to traditional air conditioning. However, technology is not suitable for all climates. For instance, in humid areas, free cooling may cause condensation that damages the hardware or necessitates additional cooling during warmer periods.

Liquid Cooling:
Liquid cooling is gaining popularity in data centers due to its efficiency. Liquid coolant is used to remove heat from the hardware, as liquids offer higher thermal capacity than air resulting in reduced energy consumption. Additionally, liquid cooling fans are quieter than traditional air-cooled fans. As a result, many data centers are turning to this technology to improve their cooling efficiency.

Liquid cooling systems can be classified into two types, namely direct and indirect. Direct liquid cooling involves direct contact between the liquid and hardware, removing heat directly from the source. On the other hand, indirect liquid cooling uses the liquid to cool a heat exchanger, which draws heat from the hardware. Although direct liquid cooling is more effective in removing heat directly from the source compared to indirect liquid cooling, it may require a higher implementation and maintenance cost.

AI-Based Cooling:
AI-based cooling systems utilize sensors to analyze data and optimize temperature and humidity levels within data centers. Furthermore, the systems can predict and prevent potential cooling issues. Implementing AI-based cooling system can reduce energy consumption and enhance cooling efficiency. However, it may involve significant upfront cost and ongoing AI Algorithms development to ensure the accuracy of the real-time data.

In Conclusion, selecting the appropriate cooling solution based on business needs is vital for data centers to ensure optimal performance, reduce energy consumption, and minimize the risk of hardware damage and downtime.
