Power supply unit variable Quint-PS

Compact power supplies that activate automatic fuses for 24VDC side for mounting on the support rail with SFB technology.
Primary-switched power supplies for mounting on DIN-/ EN support rail. The broad input voltage (primary voltage) means that the power supplies can be used virtually all over the world as well as in applications where high demands are placed on the operating safety. All power supplies are equipped with the external emergency exits which signal if the secondary voltage drops by 10% and if the power supply is overloaded (only SFB version), which also makes them suitable for applications that demand redundancy with monitoring. See also diode module QUINT-DIODE/40 for 100% redundancy connection. Power supplies in the series fulfil the standard for power factor compensation EN 61000-3-2for installation on public networks. The power supplies are also available as Ex-version (for installation in zone 2).
3-phase power supplies also deliver full power if one of the phases falls out. The secondary side is fitted with an electronic circuit protection. The protection is specially developed to reliably activate "normal" automatic fuses/miniature circuit breakers on the secondary side of the power supply if the application requires individually fused groups with SFB technologies and Power Boost.
SFB technology is specially designed to be able to activate slow miniature circuit breakers/automatic fuse protections by being able to deliver under 12 ms a current pulse of 6 times the nominal current (for example, a 10A power supply with SFB technology, delivering a 60 A pulse). This facilitates a quick and safe immediate release of the automatic fuse in the event of a short circuit which, with the traditional power supplies, would take a significant amount of time (even if it were possible).
