General Description
Deltas Lyte DIN Rail Power Supply series is designed for cost sensitive users who need to fulfill essential features needed for many
general industrial applications, without compromising on quality and reliability. The convection-cooled Lyte series will operate
between -20C to +70C, with full rated power available from -10C to +50C at 230Vac. The overcurrent protection is designed to
operate in constant current mode, which makes the Lyte series suitable for inductive and capacitive load applications. The product is
certified according to safety standards IEC/EN/UL 60950-1 for Information Technology Equipment (ITE) and UL 508 for Industrial
Control Equipment (ICE). Electromagnetic radiated and conducted emissions are compliant to EN 55032, Class B; and, the product is
fully compliant for environmental protection requirements per RoHS Directive (EU) 2015/863.
