New PULS DIN-Rail Power Supplies Support DeviceNet®

March 22, 2007 by Jeff Shepard

PULS UK announced the introduction of two new DIN-Rail power supplies aimed at the growing DeviceNet® market. DeviceNet® is a low-cost communications link used to connect industrial devices, typically in factory automation applications. Devices such as limit switches, photoelectric sensors, valve manifolds, motor starters, process sensors, bar code readers, variable frequency drives, panel displays and operator interfaces may be connected to a DeviceNet® network eliminating expensive hard wiring. The direct connectivity provides improved communication between devices as well as important device-level diagnostics not easily accessible or available through hard wired I/O interfaces.

The two PULS DeviceNet® enabled power supplies are the QS5.DNET and QS10.DNET. Both are derivatives of the Dimension QS family. The QS5.DNET offers a fixed 24Vdc output at 3.8A while the QS10.DNET has a user adjustable 24Vdc output rated at 8A.

Common features to both power supplies include 100-240Vac input range, NEC Class 2 compliance, DeviceNet® approval, up to 92% efficiency, active power factor correction, full output power over temperature range -25 to +70°C, negligibly low inrush current, DC-OK relay contact and time saving, reliable quick-connect spring-clamp terminals.

Harry Moore, Managing Director of PULS UK commented, "DeviceNet® provides a simple, networking solution that reduces the cost and time to wire and install factory automation devices. Our two new QS DeviceNet® enabled DIN-Rail powers supplies provide efficient, reliable, low cost of ownership power supplies which complement DeviceNet® control systems."

The PULS DeviceNet® Din-Rail power supplies have been specially designed to fully meet DeviceNet® requirements. The special features of PULS DeviceNet® power supplies are; the nominal and overload characteristics are designed for DeviceNet® systems, large load capacitors can be charged in a very short period of time, after turn on, the output voltage increases according to the DeviceNet® timing specification, the upper level of the output voltage is limited to protect the network.

In addition, PULS claims that its DeviceNet® Din-Rail power supplies offer outstanding high efficiency, compact size, high immunity to transients and power surges, low electromagnetic emissions and a comprehensive international approval package. A range of accessories are available to assist system builders, including a wall-mounting bracket, side mounting bracket and diode decoupling module.
