For Industrial and Medical Applications
Power supply units are used in a wide variety of industrial (IEC/EN-UL-CSA62368-1, mandatory from December 20, 2020) and medical applications (IEC/EN-UL-CSA60601-1 4th Edition). In addition to these main groups, special certifications must be covered such as the household appliance standard IEC/EN-UL- CSA60335-1, or for instance IEC/EN50155 (EN50121-32, EN61373) for railway technology, which comprises EMC (EMI), ESD, surge, transients and vibration and shock resistance.
Several manufacturers meanwhile offer a 7-year guarantee. As a key component, the power supply unit must be
- Operational 24/7
- Withstand thermal stress
- Pass safety certifications
The standard designs include 2x4“ and 3x5“ footprints, which are implemented either as "1U" or "1 inch" power supplies (height). In addition to these and the special sizes, brick sizes (ful, half, ¼) are also available.
Apart from single outputs and bipolar power supplies, the portfolio also includes adjustable power supplies with several output voltages, various interfaces such as I2C, PMBus, and auxiliary voltages with 5 and 12 V for standby operation or for fans. Power supply units (sometimes in combination with a DC/DC converter) constitute the separation section with a purely functional or basic insulation, which is part of the safety chain.
In medical applications, the power supply achieves the required creepage and clearance of the various overvoltage categories only in part. The type of insulation - double, reinforced – also plays a role, especially with medical applications (MOOP – means of operator protecion, MOPP – means of patient protection). This applies especially in the case of classifications according to NC(B), BF – body floating, CF – cardiac floating, in which patient leakage separates the wheat from the chaff. Apart from the electrical safety (LVD, ELV, SELV) required to obtain the CE mark, electromagnetic compatibility (EMC, EMI) also plays a decisive role. As regards radio interference, IEC/EN55022 (CISPR22) class A applies to industrial applications and class B to commercial consumer appliances. Moreover, the standards ErP 2009/125/EC (Europe) and DoE(US) regulating no-load losses and efficiency under various load conditions must be considered.
