ELECTRIC.IE • The Magazine & Website for the Irish Electrical Industry • 49 Phoenix Contact New voltage variants under 100 W The Quint Power power supplies from Phoenix Contact in the power range up to 100 W are now also available with special voltages of 5 V and 12 V. Three new singlephase power supply units (5 V DC with 5 A, 12 V DC with 2.5 A and 7.5 A) supplement the portfolio, which until now has included 24 V devices in the power range of up to 100 W. For small sizes the power supply units provide high system availability with preventive function monitoring and power reserve – even in the low power range. Dynamic boost with up to 200% of the nominal power for 5 s ensures that dif cult loads start. The system can be easily extended by static boost which continuously provides up to 125% of the nominal power. The power supplies also have a high ef ciency of 92.4% and a long service life, with low power dissipation and low heating. Selectable power thresholds and DC OK signaling enable output parameter monitoring tailored to the application. The preventive function monitoring feature warns of critical operating states before faults occur. Pushin connection technology makes commissioning quick and easy. The narrow, at design of the devices also saves space in control cabinets. The power supply units have a DC input voltage range from 88 V DC to 350 V DC. Narrow protection for 3-conductor applications This means that narrow protective devices for 3-conductor applications with an overall width of 6 mm are available with immediate effect. These products fit seamlessly into the TERMITRAB complete product range, and also feature advantages such as the pluggable design and the advantages of optional visual remote signaling. There is also a new, pluggable solution for intrinsically safe areas: the new TTC-6P-3 surge protective devices have a much higher rated current, at 5 A, than the HF variants. The new protective devices for ‒Phoenix Contact is adding a customized solution for impedance-sensitive signal circuits with more than two signal wires to its Termitrab complete range of narrow surge protective devices for MCR technology. 3-conductor applications are typically used in temperature measurements, for example. The lack of resistors in the protective circuit means there is no fundamental attenuation. There is no impact on the measuring signals.
