This new series AM40EW-NZ provides a wide input voltage range of 40-160VDC
required by input voltages of 72V, 96V, 110V in railway industry. Outputs and
isolation voltage up to 3000VDC/1500VAC ensure them to meet the railway
locomotive EN50155 standard requirements and EN62368 standard requirements.
The converters also offer a wide operating temperature range of -40℃ to +85℃.
Protections for input UVP, OSC, OCP, OVP and OTP are also included. Housed in 2x1
inch package, this AM40EW-NZ series is available for packages with optional heat
sink in PCB mount, chassis mount and DIN rail mount, which offers flexibility to the
designer of the end-product and makes this series ideal for applications in railway
monitoring, lighting equipment, information display and other railway vehicle-
related equipment.

Note: Use
suffix “-K” for optional heat sink. Use suffix “ST” for chassis and suffix “STD” for DIN-Rail
mounting
(ex. AM40EW-11005SH30-NZ-K-STD is with the heatsink attached version. AM40EW-11005SH30-NZ-K-STD is DIN-Rail mounting version with the
heatsink. AM40EW-11005SH30-NZ-ST is chassis mounting and AM40EW-11005SH30-NZ-STD is DIN-Rail mounting version.)
