LED power supply features high efficiency, triple dimming function
In comparison to the product families PLN-60 and PLP-60 which have been introduced earlier, the efficiency of the new ones has been raised by another 1 to 4 percent points. The warranty has been extended from two to three years. Also with regard to operating temperatures the new power supplies offer superior performance: At normal supply voltages of 230 VAC they can be used already at temperatures as low as -40 °C while the PLN/PLP-60 only operate at temperatures of -30 C° or higher. In addition, the HLN-80H and the HLP-80H are equipped with a triple dimming function – DC 1-V to 10-V input; PWM or external resistor. Thus, they can meet the rising demand for energy-saving solutions in dimmable lighting.
The new power supplies can be operated across a particularly wide input voltage range – from 90 VAC to 305 VAC. Thus they are fit for use not only in the common AC supply grid with voltages of 115 V and 230 V but also in split-phase networks with 277 V widespread in North America.
With their integrated 2-stage active reactive power compensation, the HLN-80H and the HLP-80H meet the requirements to attenuate harmonics according to EN61000-3-2 under operating conditions exceeding 60 % load. At this condition, the power factor rises to beyond 0.9.
The power supplies resist transients of up to 4 kV and thus meet the requirements for deployment in general lighting applications. Due to their high efficiency of up to 91%, the HLM-80H suits for fanless operation at temperatures of up to 50 °C. With operating temperatures of up to +70 °C, the HLP-80H meets the requirements for closed systems.
The products feature protection against short circuit, overvoltage, overload and overtemperature. Certification according to lighting safety standards such as UL8750 and EN61347-2-13 has been applied for at institutions such as UL, CUL, TÜV and CE.
In Germany these products are available through power supply distributor Emtron electronic GmbH. For more information please visit www.emtron.de.
