PowerUnits
Efficient Industrial Electronics ...
We are proud to have partnered with PowerUnits Leistungselektronik GmbH for over 15 years. Based in Austria, PowerUnits specializes in electronics and is a leading manufacturer of highly efficient and intelligent electronic power supplies.
The electronic ballasts are designed to operate medium-pressure High-Power Ultra-Violet (HPUV) lamps. They are characterized by their exceptionally high efficiency, compact and lightweight design, and low-frequency AC square-wave operation, which ensures consistent irradiation from the lamps. These devices, combined with extremely high ignition voltages, can start and operate virtually all UV lamps regardless of their arc length or dose type.
Each device is made exclusively from the highest quality materials, semiconductors, and electronic components manufactured in the world. Every unit undergoes a fully automated 100% functional test, followed by a burn-in procedure during the production process. Only after successfully passing these rigorous testing procedures are they delivered to clients worldwide.
PowerUnits electronic ballasts are distinguished by the following technical advantages and competitive benefits.
Technical advantanges
Technology
The EfficientSwitchTM technology enables virtually loss-free current commutation to the half-bridge circuits. This allows a significant reduction in the switching losses, enabling a more compact and lightweight design, lower EMC and a unique control performance.
The low-frequency AC square-wave operation guarantees even irradiation with a virtually unmodulated power flow. This enables optimum activation of virtually any lamp type and power.
Low-frequency AC square wave operation
An integrated microcontroller enables real power control of the lamp power from 5% to 100%. This allows for compensation of lamp voltage tolerances and guarantees a production result that can be reproduced exactly. No power reserves are necessary. Mains voltage fluctuations are optimally adjusted. In the case of longer breaks, the lamp power can be reduced with ease, thus saving on energy costs.
Real Power Control
The integrated ignitor supplies energy-rich and lamp-friendly pulse trains with a sinus amplitude of up to 5,000V. The start sequence enables an optimum, fast and gentle lamp start for any lamp type. The lamp cable length has no negative influence on the ignition behaviour. All in all, the lamp service life and even so-called “lazy ignitor” lamps can be optimally ignited.
Integrated high-frequency ignition
Wide-range input
The device can be used irrespective of the mains frequency (48Hz – 62Hz) at a three-phase mains voltage of between 360VAC and 530VAC. This gives equipment manufacturers the maximum possible flexibility and reduces both storage and logistics costs.
The low-frequency AC square-wave operation minimises the risk of EMC problems especially in applications with longer lamp cable lengths, as is conventional in the timber or chemicals industry. The integrated automatic ignition sequence adapts to a very wide range of cable lengths and guarantees the best possible lamp ignition.
Lamp Cable length of up to 300m
PELV safety standard
The control signals are isolated from the mains, are designed to be short-circuit-proof and have a near-earth ground. The PELV (Protective Extra Low Voltage) protective measure can be implemented with extreme ease.
The real AC mains voltage measurement integrated as standard offers the maximum possible protection for the device and enables valuable feedback to be provided to the system control.
Real AC mains voltage measurement
Compatible with the IT mains systems
As the only device of its kind in the world at the present time, the “EfficientSwitchTM” technology is compatible with the IT mains without any need for further technical intervention and, at the same time, complies with the European EMC standards.
The device is available with common protocols, ModBus and CANopen. The CANopen protocol was officially designed in accordance with CIA (CANopen is internationally standardized, EN 50325-4) and is officially registered with CIA.
Field bus options
No zero conductor necessary
Thanks to their customer-orientated design the devices does not require a zero conductor. Combined with the wide-range input, this offers the maximum possible market coverage.
PowerUnits utilizes exclusively high-quality materials and components that comply fully with RoHS regulations as detailed in Directive 2002/95/EC. This directive, originating from the European Union, imposes stringent restrictions on the use of certain hazardous materials commonly found in electrical and electronic products (EEE).
RoHS Compliant
EC Conformance
The electronic products are designed and manufactured to strictly fulfill EC Conformance standards, which are essential for meeting EU health, safety, and environmental requirements. The stringent adherence to these standards not only promotes compliance but also significantly enhances consumer safety and confidence in the products they use.
The electronic products are accredited with the GS Certificate by TUV SUD America based on tests and evaluations compliant with EN IEC 62368-1:2020/A11:2020. With the globally recognized GS mark, PowerUnits ensures that its products meet the quality and safety requirements outlined in the German Product Safety Act (ProdSG, for short). This certificate serves as a valuable aid for purchasing decisions and enhances customers’ trust and confidence.
GS Certified
UL & CSA Certified
PowerUnits electronic ballasts are accredited with UL & CSA Certifications, based on tests & evaluations in accordance with UL 62368-1:2019/R:2021-10 and CSA C22.2 No. 62368-1:2019, conducted by TUV SUD America. UL, the abbreviation of Underwriters Laboratories, is a highly reputable and globally recognized safety certification that ensures electronic products meet specific safety, performance, and quality standards. The certification of UL provides PowerUnits with a competitive edge by demonstrating an unwavering commitment to meeting product safety and industry regulations.
