TDK Corporation announces the introduction of the TDK-Lambda DRB series of DIN rail power supplies for low power applications that require keenly priced basic functionality. Designed to support the growing trend for simple and economic DIN power solutions in industrial, building automation and process control applications, the DRB series combines low cost and extremely compact dimensions with industry leading efficiency of up to 91%. No load power consumption is between <0.3W and <0.5W depending on the model type.

“There’s strong customer demand for compact, convection cooled DIN rail power supplies that deliver their rated power without compromising long-term reliability,” says Martin Southam, Director of Marketing, TDK-Lambda EMEA. “Housed in a robust plastic case, the DRB supplies feature a narrow design, ranging from 18mm to 45mm, saving space on the DIN rail. We believe that these are the smallest products of their kind on the market. The DRB series is also perfect for customers working to ErP or Eco-Design guidelines.”

The supplies operate from a universal input of 85~264Vac and have EN61000-3-2 compliance, enabling worldwide use; moreover, they can withstand voltage of 300Vac surge for 5 seconds. The DRB series is available with 4 output power levels ranging from 15 – 100W and nominal output voltages of 5V, 12-15V, 24V or 48Vdc.

The supplies can operate at full load over a wide temperature range of -10 to +55°C (+70°C for 15W model). Typical ripple and noise is below 40mV and a green LED indicates DC OK. Other features include over current and over voltage protection, and a hold-up time of up to 20 ms at 100Vac input voltage, full load.

The smallest model measures just 18mm x 75mm x 90mm (DRB15-24-1); all DRB models will mount on either a TS35/7.5 or TS35/15 DIN rail offering engineers a flexible option for the various applications. In addition, they have been rigorously tested for shock and vibration while mounted onto the rail.

The DRB series is approved to UL508 safety standard for industrial control equipment. Further safety approvals include IEC/EN 60950-1 (2nd Ed.) and UL/CSA 60950-1. CE marked in accordance with the LV Directive, EMC Directive and RoHS Directive, the power supplies are designed to meet EN55022 and CISPR22 Class B for conducted and radiated EMI, and include a three-year warranty.

Hylec-APL has added two IP68 electrical connectors to its waterproof range which have diameters that are less than that of a one pound coin. The inline connectors both use cable gland technology to form a completely weatherproof seal without the need for silicone gel. The connectors are designed so that the terminals form part of the outer casing making the overall diameter of the connectors just 23mm.

* Mini-TeeTube and mini-TeePlug have an innovative design which incorporates the wire terminals as part of the external housing.
* Housing ends features a dome topped cable gland and co-moulded sealing rings ensuring a high IP rating when assembly is complete.
* Both connectors can be ordered in 2, 3 or 4 pole options.
* Quick installation, wire piercing screw terminal blocks are also available which make it possible to secure the connection to IP68 standards in less than a minute.

The Schurter chip fuses are available in a number of different current ratings from 50 mA to 25 A at a rated voltage of up to 125 VAC/VDC. Depending on the version and voltage ratings, a breaking capacity of up to 600 A is reached. Thanks to these impressively high values and variety, these chip fuses can be used in a wide range of applications. Chip fuses are especially suitable for mobile and battery-operated devices in sensor technology and industrial electronics.

SCHURTER chip fuses set themselves apart from comparable products through their extremely precise opening times and minimal power dissipation. In addition, their solid construction makes them especially resistant to vibrations and pulse loads. Furthermore, the SMD contacts, some of which are gold-plated, have a positive influence on the wettability, storage life and electrical quality of the chip fuses.

All Schurter chip fuses come with cURus certification. The USI 1206 is additionally VDEapproved, the only chip fuse with this type of certification available in the market. As halogen-free and RoHS-conform fuses, Schurter chip fuses, moreover be used for lead-free soldering
processes.

Finder has expanded its range of solid state relays to include high current ‘hockey puck’ style relays, offering rapid cycling and near infinite switching capability.
 
The new 77 Series relays are ideal for use where applications require the control of exceptionally high inrush current demands, such as in LED and other low-energy lighting, switch-mode power supplies, building control, and motor switching.
 
With a sealed construction and no wearing parts, they are less sensitive to environmental factors such as mechanical shock, vibration, humidity and external magnetic fields, providing an increased lifetime of the relay.
 
Finder’s ‘hockey puck’ relays are electronically clean with low emissions, no contact bounce, and no electrical arcing—making them suitable for sensitive environments. The silent operation makes them ideal for residential and commercial usage.

Crouzet Automation presents a set of energy counting solutions for commercial or industrial buildings, machines and installations. Thanks to its highly visible display, Millenium 3 is the right solution to visualize and centralize multiple energy meters with pulse outputs.

Up to seven pulse inputs, coming from different kinds of metering equipment, (energy, water, calories, etc.) are treated to display monthly consumption. This consumption can be tracked with the memory of the previous month, the total by use and the sum of the total uses.

The M3 Energy Expert solution is a set of macros functions delivered with associated literature. These macro functions can be easily interconnected to build Energy Management applications using M3 Soft V3.0 AC8. They are compatible with all metering products with pulse outputs!

You can adapt the application: change the number/name of uses, adapt the parameters to the metering equipment (100 – 1000 – 50 – 500 Pulse/kWh), use relay outputs for alarms, and add some other automation functions.
