The flexibility of bench power supplies (with fully adjustable outputs and ease of
portability) and the simple mechanical concept found in modular sub-units, are
combined in the Farnell B30 range. Result-economical, utility power supplies
suitable for a wide variety of applications in various locations. They can be used on
or under the laboratory bench. Or built into test benches or equipment. Wherever a
convenient adjustable source of d.c. power is needed, without the necessity for
constant metering, specify a B30 range unit. There are four units in the range.
Output voltage on all models is 0 to 30 volts available in steps of 6 volts each with
overlapping fine control between each step. Maximum current of 2, 5, 10 and 20
amps for the respective models is available at any voltage setting.
Units may be connected directly in series parallel to obtain increased voltage or
current. Feedback terminals are provided for remote sensing of the voltage at the
load so that the effects of resistance in the load connecting leads may be minimised
if required. Electronic current limiting circuitry and input and output fuses protect
the unit against overload or accidental short circuits. The limiting circuitry auto
matically resets itself when the overload is cleared. There is a cable wrap under -
neath the unit for stowing the permanently attached mains lead.
