Some of these power supplies can deliver dangerous voltages and currents.

If unsure how to use them safely, ask.

Location: electronics test bench and shelves, but if members forget to put them back after using them, they might be anywhere.

Farnell PDD3502A Isotech IPS1125 Farnell TOPS2 Farnell TSV70 mk2
Specification variable 0-35V, variable current limit 0-2A variable 0-20V 0-250mA, fixed 5V 1A variable 4-6V 5A, variable 12-17V 1A variable 0-35/70V, variable current limit 0-10/5A
dual independent and tracking PSUs triple independent PSUs single plus dual tracking PSUs single PSU
Condition Modern, high quality Modern basic Old basic, untested but good provenance Old, seems to be working
Can connect PSUs in series and parallel Caution w.r.t. the fixed current limitCaution w.r.t. unknown current limits; might be via fuses! Caution: shorting 10A could cause molten metal to splatter; recommend using with eye/face protection
Ideal for logic plus analogue Ideal for logic plus analogue Caution: requires the sense wires to be connected
Caution: weighs 26kg, so two man lift
Farnell L30AT Rapid PS3025 Farnell ET30/2
Specification variable 0-50V, variable current limit 0-500mA variable 0-30V, variable current limit 0-2.5A variable 0-15V/2A or 0-30V/1A, fixed current limit
dual independent PSUs fixed 12V & 5V, 500mA dual independent PSUs
Condition Old but usable Excellent Old but usable
volts controls scratchy <2V Caution w.r.t. the current limits fixed at ~10% above the rated current
current limit controls scratchy
both satisfactory once settled

There are many many PSU bricks that can be hacked, located on the shelves near the glass door.
