Phoenix Contact’s new dip-coated Quint power supply units provide a way to protect all PCB components. The power supplies, which have an adjustable output voltage from 18 to 29,5 V d.c. and output currents of 5, 10 and 20 A, are therefore capable of tolerating 100% humidity. In contrast to spray painting, even through-hole mounted components like bridge rectifiers and power semiconductors are completely covered with paint.
Input voltages from 85 to 264 V a.c. or 90 to 350 V d.c. supply the three single-phase devices. The three-phase module with 20 A nominal output current can be operated on networks with 3x 320-575 V a.c. or 450-800 V d.c. Offering an efficiency of up to 93%, the devices generate minimal heat loss, thus not only saving energy but also extending the service life of the components. The wide temperature range of –25°C to +70°C makes the unit suitable for use in a variety of applications.
In addition to the usual industrial approvals, the dip-coated modules with nominal currents of 5 A and 10 A conform to EN 60079-15 (ATEX directive). They can be installed in a potentially explosive area in which Category 3G equipment is required; the modules are also IECEx certified. All Quint Power devices comply with UL standard ANSI/ISA 12.12.01 as well as the specifications for Class I, Division 2, Groups A, B, C, and D (hazardous locations).
