In particular the SPDM Series power supplies are significantly smaller than the standard power supplies of the same power. The greater compactness is achieved thanks to limited energy loss, that automatically generates greater effectiveness. This specific SPDM Series 75W Power supplies are available with 12VDC or 24VDC Output Voltage, with spring or screw terminals. **Ordering Key SP D M 12 75 1 B** ~~oe~~ **Model Mounting (D = Din rail) Medium width Output voltage Size Input type Spring terminal (Nil= Screw terminal)** =I) **Approvals** **==> picture [52 x 5] intentionally omitted <==** **----- Start of picture text -----**
