The construction of this assembly was made together with Retech AG in
Switzerland. Retech is a specialist supplier of controllers for the textile
industry (retech@netlink.ch)
The power board is shown mounted on to 16 solid-state relays. The relays
are mounted first on an aluminium heat-sink and the power board screwed
to these relays. Three power phases are distributed between the relays (channels
1..5 use phase 1, channels 6..10 phase 2 and channels 11..16 phase 3). Connection
between the power board LS08-16 and the controller board CR08-16
is via a flat-band cable. The controller card can be mounted via distance
bolts directly above the power board.
Summary of features:
3-phase 40A 240V AC main connector (phase 1, phase 2, phase 3, neutral, earth)
16 single phase heater outputs, each individually regulated and with 8 A fuse
Optically isolated phase detectors
Creepage and clearance respects toughest operating environment (6mm between primary and secondary circuits; 3mm between phases, neutral and earth)
Double sided board with 105um copper layers; 424mm x 224mm
LS08-16 Power Board (note that the solid state relays are screwed
to the power board and mounted beneath it on an aluminium plate, acting
also as heat-sink)
