Programmable switcher supplies from 0.8 Vdc

The PIV Series 160-W programmable switch-mode
power supply delivers from 0.8 to 120 Vdc at up
to 20 A in a constant-voltage or constant-current
mode. Input voltage range is from 85 to 132 Vac
or 170 to 264 Vac.

Features include adjustable overvoltage
protection, input surge protection, remote
sensing, and fan cooling. ($744 ea/large
qty--stock to 10 weeks ARO.)
