LDN85 Series are single phase DIN Rail Switching Power Supplies,
ideal for home automation, simple automation in machines, survey
systems, telecom, but also the renewable energy field.
Its compact size, high efficiency, excellent reliability and excellent
power/volume ratio, together with easy installation due to pluggable
connectors makes it ideal for various industrial and renewable
applications.
LDN85 Series are Class I isolation devices suitable for SELV and PELV
circuitry and are designed to be mounted on DIN rail and installed
inside a protective enclosure.
Single phase AC input 90 – 264 VAC (110 - 345 VDC)
High efficiencies and in compact size
150% overload capability
Only 40 mm width aluminum enclosure
Short circuit, overload and over temperature protection
Up to 70°C operating temperature with no derating
RoHS Compliant
