Opus HE 7U Modular Battery Chargers DC UPS Opus HE 12U Modular Battery Chargers DC UPS Proven Quality & Reliability More than ten years providing OPUS  DC systems to the industrial sector in New Zealand, Australia and Asia have reassured the high level of reliability and quality of Opus DC Systems. Power Utilities, Refineries, Mining and  Critical Infrastructure ( Hospitals & Transport Centres) have been few of the applications where our Turnkey  Solutions are installed. Check out the case study below; we had the opportunity to supply six redundant, modular & fanless battery charger systems to the power grid company in Bangladesh. For this specific project, we integrated the first version of Opus MRC Rectifiers and 7U Rack Mount System (still available) which have the same level of reliability but less power density.

FCS Series – Low-cost, Open-Frame 40W & 60W Power Supplies

Helios Power Solutions has launched two new series of low-profile, open-frame power supplies addressing the need for ultra low-cost 40W and 60W solutions that support a broad range of applications within the medical, domestic/household and ITE/industrial sectors. Most markets are under price pressure these days; the new FCS40 and FCS60 address this need by combining low unit cost with easy integration into multiple end equipment markets with international agency approvals, high efficiency and low emissions. This is further supported by the wide operating temperature (-25°C to +70°C) that allows use in a wide variety of environments. The new FCS40 & 60 supplies offer a single output of either 12, 15, 18, 24, 36 or 48V at efficiencies up to 86%, model dependant. An on-board potentiometer allows the voltage to be trimmed by ±10%, optimising the voltage for specific load requirements or voltage drops. Both the FCS40 and FCS60 carry extensive approvals that ease the task of the designer in obtaining system-level approval for their designs. For medical applications these include IEC/EN/ES60601 offering 2 x Means of Patient Protection (MOPP). The units also include two line input fuses and offer Class II operation, furthering their suitability for medical applications in the home healthcare environment. For ITE & industrial applications the supplies are approved to IEC60950-1 and IEC/EN/cUL62368-1 as well as meeting the needs of the Low Voltage Directive (LVD). IEC60335-1 approval makes the FCS40 and FCS60 applicable to domestic & household applications. As part of XP Power’s ‘Green Power’ range, all of the new supplies minimise the no load power consumption to less than 0.3W, facilitating compliance with the latest environmental legislation. The ability to be convection cooled up to +70°C with de-rating removes the need for a fan from many systems, saving energy, cost and weight as well as improving system reliability.

IEC protection classes for power supplies

Posted by Andrew Bryars on 05 Nov 2018 Power supplies fall into one of three protection classes based on the need, or not, for a protective earth connection:   Class I   – where user protection from electric shock is achieved through a combination of insulation and a protective ground. Class II  – where user protection from electric shock is achieved through two levels of insulation (either double or reinforced) Class III – where the input is connected to a safety extra low voltage (SELV) circuit meaning no further protection is required.   It is important to note the distinction between a class II power supply as described above and a class 2. Limited Power Source (LPS) power supply which relates to the VA rating of the output being limited. A class 2 power supply has a maximum output VA rating of 100VA if the power factor is less than 0.9 or 100W if the power factor is above 0.9. In addition, the maximum allowable output current under any condition is 8A and the maximum output voltage under any condition is 30VDC. The requirements for a class 2 power supply meeting UL1310 are the same as one which meets the limited power source (LPS) requirements of UL60950-1 & UL62368-1. Use of a class II external power supply is straight-forward with only a 2-core mains lead being required for safe operation as the difference between it and a class I product. A class II component or open frame power supply needs no earth connection for safe operation, but the minimum distance from any live part to the enclosure must be observed whether the enclosure is conductive or not to maintain the two levels of protection needed against a single failure in the system. While a class II power supply does not require a protective earth, some lower power class II products find applications in class I systems and some class II applications use a functional earth in the system. The class II supply is designed to meet EMC requirements for emissions and immunity, but if the output of the supply is connected to safety earth or a functional ground it will create a low impedance path for noise altering the power supply’s characteristic performance and it is likely that extra filter components will need to be fitted external to the power supply for emissions compliance.
