The Transtar Ch-eol-41 Electronic Power Supply is a power solution specifically designed for powering fluorescent lamps. In this case, the model number is 9558721 and is made by Transtar in collaboration with Nedap. This model operates at an efficiency range of -10% to +10% of the operating voltage AC that is 220 to 277V, and its frequency range goes from 47 to 63Hz. Doing so, it takes a maximum current of 0.40A. The open-loop tolerance of the output voltage it generates is in the range of 220 to 300VDC, within a ±10% accuracy level. The power supply with this model can then fit not just one 36W but two 18W fluorescent lamps during its EOL stage, suggesting that this product could be used in different applications in lighting. This operates in an extreme condition. The maximum temperature rating is at 90°C with its certification to Kema 00Atex2121U. It makes sure that there is a safety standard conformity in explosive atmospheres, ranging from (II 2Gd Eex Qe II). The part number of the Transtar Ch-eol-41 is G7536-2240-eol. The product code is 0033520051. It weighs 1.240 kg. The electronic power supply, made in the EC, encompasses all attributes of high engineering and manufacturing with a view to deliver a tough, reliable, and efficient power solution for commercial and industrial applications.
