New Modular OPUS HE Battery Charger Systems for Industrial Applications
The new Efore OPUS HE family of 19” rack-mount DC power systems are high-efficiency power solutions powered by the new MHE 2kW high-efficiency rectifiers. The 7U rack configuration delivers up to 6 kW of power, while the 12U configuration delivers up to 10 kW. Their robust and reliable fan-free design, modular architecture and use of established components – including the VIDI+ controller and flexible distribution options – ensures the lowest total cost of ownership (TCO) across the 15-20 year expected life span for industrial backup power systems. The OPUS HE series products offer unrivalled efficiency of 97% for minimal environmental impact. They have been designed and optimized for critical infrastructure, distribution and transmission substations, process industries, and railway substations where reliability is always the top priority. New MHE Rectifiers – 5 Warranty MHE rectifiers are convection cooled and require no fans. Rated output power is 2000 W in 48 V – 220 V output versions and 1500 W in 24 V version. Rectifier input is single phase, range 85-300 VAC. 2000 W output power, 24 VDC 1500 W Soft-start generator input feature Active load current sharing Internal over temperature protection Digital communication over CAN bus with Efore VIDI controller Modular Battery Chargers – DC UPS with MHE Rectifiers The MHE rectifier is designed to supply power to industrial and telecom backup power systems. It should only be assembled and used in a system cabinet or sub-rack where human contact with hazardous voltages is prevented.19” 12U Rack delivers maximum 10 kW output power at 48, 60, 110, 125 and 220 VDC and 7.5 kW at 24 VDC output and 19” 7U Rack delivers maximum 6 kW output power at 48, 60, 110, 125 and 220 VDC and 4.5 kW at 24 VDC output. These rack systems support all typical Lead Acid and Ni-Cad battery systems in nominal 24, 48, 60, 110, 125 and 220 voltages. 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.

The DDC15 and DDC30 will now include the DDC40 range of models that offer a choice of 5, 9, 12, 15 or 24 VDC nominal outputs, from an input range of 10-32VDC. Packaged in a low profile design measuring 91x53x57mm. The range is designed to offer additional voltages in DIN rail power systems, provide isolated outputs & noise immunity or support battery powered or battery-backed applications. Capable of operating over a wide temperature range from – 40 to + 70 degrees C, the DDC series delivers full power up to +50 degrees C and suits use in most environments where the applications require extended operating temperatures. The front panel hosts two LEDs that provide an indication of DC ON & DC low status along with access to screw terminals for input and output connections. Added extra features include Remote ON/OFF control and output adjustment via potentiometer. The DDC series provides convenience for the system designer in accommodating additional supply voltages from a single DIN rail installation rather than having to incorporate multiple power supply formats.
