LDW480 Series are single, two or three phase DIN Rail Switching
Power Supplies with active PFC.
Its compact size, high efficiency, excellent reliability together with easy
installation makes it ideal for various industrial, telecom and renewable
energy applications.
LDW480 Series are Class I isolation devices suitable for SELV and
PELV circuitry (up to 48 VDC models) and are designed to be mounted
on DIN rail and installed inside a protective enclosure.
