Quint Oring: active redundancy for high system availability

The Quint Oring active redundancy module for an output current of 80A is a new addition to Phoenix Contact's line that already includes 20A and 40A models. For the first time, there is an option available that makes it possible to significantly increase the operational reliability of the overall redundant power supply concept for high-rated power PSUs.

In addition to decoupling, continuous monitoring is also important. In order to detect critical operating states early on, the modules provide information on the output voltages of the power supply units, defects in the wiring or decoupling section, and the present load current. Permanently monitoring the load current offers an important advantage when expanding or upgrading systems. If additional loads are connected to a redundant power supply when expanding the plant or system, this can result in a loss of redundancy. The system operator will immediately be aware of a loss of redundancy as the Oring module signals the overload condition.

ACB (Auto Current Balancing) technology doubles the service life of the redundant power supplies, ensuring that both units work under the same load. The load current is automatically distributed in a balanced manner. The 1 × 20A, 1 × 40A, and 1 × 80A modules are suitable for DC voltages of 18-30V. The 32, 38, and 66mm-wide units are simply snapped into place on the mounting rail. Suited to industrial environments, they operate at ambient temperatures extending from -25degC to +70degC and carry continuous currents of 2 × 15A, 2 × 26A, or 2 × 45A at ambient temperatures up to +40degC.

The Quint Oring redundancy module uses MOSFETs for decoupling instead of the usual Schottky or silicon diodes, therefore saving up to 70 per cent energy. Using two positive output terminals, the wiring can be redundantly routed to the loads. For further information please visit www.phoenixcontact.co.uk.

Tackling noise emissions from industrial machinery
Employers and dutyholders are required under the Provision and Use of Work Equipment Regulations 1998 (PUWER) to provide workers with equipment that meets relevant supply laws. They must also adhere to the Control of Noise at Work Regulations, and the Health and Safety Executive (HSE) offers guidance which sets out an employer’s legal obligations. Paul Taylor, business development director for industrial services at TÜV SÜD, looks at the issue of machinery noise.
