SDN-D High Performance DIN Rail Series

In spite of its small size, the SDN-D high performance DIN

rail power supply boasts one of the highest efciencies
available in the market today. Higher efciency means

less heat is generated, potentially extending the life of
all components in the enclosure. Extensive diagnostic
monitoring capabilities are possible with the optional SCM
network communication module, which utilizes popular
industrial network protocols to provide critical power supply
data to computers, PLCs, DCSs HMIs, and other devices.
For applications requiring even higher reliability, combine
the SDN-D with SDN redundancy modules. With its
extensive capabilities, compact design, and notable global

certications, the SDN-D is the ideal solution for use in harsh

environments, extreme temperatures (–40 °C to +70 °C),
and hazardous locations worldwide.

Power supplies can be connected in parallel for increased power. However, for loads higher than 100% of individual SDN-D,

it is recommended that power supplies are initially powered up with no load applied. The outputs of SDN-D should also be adjusted

to <100mV of each other. Otherwise, unexpected results may occur due to differences in power up time for each power supply.
