Black Box Industrial SFP/SFP Multi-Power Mode Converter DC Terminal Block Option, LGC300A-R2

Chapter 3: Install the Industrial SFP/SFP Multi-Power Mode Converter

•User supplied LPS DC power via a four-position DC power block.

•Power from an Power Tray 18-Slot DC

For extended temperature operation the DC terminal block must be used because the supplied AC to DC converter is not rated for extended temperature operation. The power source used with the DC terminal block should be a Limited Power Source (LPS).

3.3.1DC Terminal Block Option

The Industrial SFP/SFP DC power option includes a 7 VDC to 50 VDC terminal block and a standard +5 VDC mini-jack. The DC terminal block has multiple DC inputs intended for cascading DC power to an adjacent unit.

Connect the power source to any one positive and one negative terminal on the Industrial SFP/SFP.

NOTE

When using stranded wire, the leads must be tinned. The chassis is not protected against mis-wiring; if mis-wired the chassis will not function. The chassis is internally connected to the negative power terminal.

3.3.2Cascading DC Power

If installing multiple Industrial SFP/SFPs on a DIN rail, you can use one DC input source and then cascade from one DC terminal block to the next, until reaching the maximum electrical current available.
