Hylec launches Debox SL2: The First 5 Pole Screwless In-Line Junction Box

The first 5 pole screwless in line junction box on the market with 5 approved 32A lever connectors; supplied with all components for completely tool-free faster installation

Hylec-APL, the specialist supplier of electrical components and enclosures, has announced the launch of Debox SL2, a completely tool-free in-line junction box which comes complete with five approved lever connectors. Debox SL2 is the smallest junction box with five poles on the market and the only product supplied complete with 5 screw free terminals: each individual 32A lever connector can take up to three conductors. Debox SL2 saves professional electrical contractors valuable time and makes installation easier for smaller and larger internal wiring jobs, as everything needed is supplied with the box and there is no need to use a screwdriver to securely join wires. Thanks to its design, Debox SL2 ends the frustration of dropping tiny screws on the floor, which then have to be retrieved, or not having required components on hand.

A first to the market from Hylec, Debox SL2 is a registered design and suitable for joining either flat or round profile cable with a minimum conductor size of 0.5mm and a maximum of 2.5mm. It is simple to use – after inserting cables and closing the levers, the lid of the box is simply snapped shut and secured with the butterfly clip supplied. To enable the Debox SL2 to be re-opened requires a tool, which complies with current regulations.

Safety is always paramount for electrical components and the Debox range, including the new Debox SL2, is flame retardant to UL940V 0 and conforms to the EN60598-1 (13.2.2) Glow Wire Test. Debox SL2 measures a compact 116mm x 45mm x 33mm and is manufactured from white polypropylene. With a temperature rating of -20degC to +85degC, it is maintenance free and suitable for all internal applications.

Debox SL2 joins the other highly successful Debox in-line junction box products, Debox SL and Debox S. Debox SL, which has four lever connectors, was the first 100% tool less / screwless in line junction box available on the UK market and has since sold in the millions of units.

Schurter GP21 / GS21: 400 VDC Connector System According to IEC TS 62735-1

Schurter Logo1.jpg

• First IEC connector system on the market for 400 VDC according to TS 62735-1 (2.6 kW)
• Designed for PDU and UPS in Data Center
• Various terminal options
• Safe disconnect under load

With the GP21 plug connector and the GS21 socket-outlet, SCHURTER launches the world’s first UL approved IEC TS 62735-1 standardized DC connector system designed to enable efficient DC power distribution in data centre power distribution strips and UPS.

 

With a complete DC power supply architecture, from source to load, the cost-intensive and failure-prone transformations and conversions, including their components, are completely eliminated. Operational reliability increases with improved efficiency.

In the digital age, vast quantities of DC-powered devices are in use: consumer electronics, industrial IT, communications technology, and electric vehicles to name a few. New technologies are beginning to emerge to enable direct current at the source of supply, which in turn is driving the establishment of standards.

 

Direct current improves the quality of the power being supplied. Problems with harmonics and harmonic distortions are eliminated. Phase compensation is also not necessary. Furthermore, coupling synchronization to different sources and networks is no longer necessary.

IEC TS 62735-1
The new standard for DC power distribution up to 2.6 kW requires a more complex design. The Connector system must be designed considering the potential for arcing associated with disconnecting the DC power supply. The permissible temperature range of the connector pins is -5 °C to +105 °C. An additional interlock for arc protection, while hot plugging, is not required for the version up to 2.6 kW.

Plug GP21 / Socket-Outlet GS21
The re-connectable SCHURTER GP21 plug accommodates a cable cross-section of between 0.75mm²/18 AWG and 1.5 mm²/16 AWG. The corresponding socket-outlet GS21 is designed for front panel thicknesses of 1.5 mm or 2.0 mm. Quick Connect 6.3 x 0.8 mm or PCB terminals are available for the connection.

Outlook
The reduction of steps to convert power resulting in less power loss, clearly speaks to the need for the use of DC power supply in data centres.

IEC TS 62735-2 is in process for the standardization of a higher DC power requirement of up to 5.2 kW. The appropriate interconnect with the necessary safety interlock (cold switch) are currently being developed.

To increase operational safety, SCHURTER will also be equipping its 2.6 kW plug with a cord retaining system. Appliance-side DC components, such as inlets and cord connectors, are being standardized in IEC TS 63236. This standard is currently in the draft phase and is expected to be published by the IEC in 2021.
