Farnell TSV 70 - Introduction; Supply Description

SECTION 1.
INTRODUCTION.
The supply type TSV. 70 Mk. II provides a source of
stabilised D.C. voltage variable over two ranges, O to 70 volts
at output currents up to 5 amps or 0 to 35 volts at output
currents up to 10 amps, range selection being achieved by a
Switch on the instrument front panel.
The output voltage is set by coarse and fine controls
on the unit front panel, and is cont inuously variable over
each range.
An output on/off switch is incorporated, allowing
the load to be disconnected from the supply without switching
off the mains input to the unit.
Overload protection is provided in the form of a
constant current limit. The current limit level is
Output voltage and current are monitored independent ly
by front panel meters. The meter ranges are selected
The instrument operates from 50/60 Hz supplies of
105 to 120 volts on 210 to 240 volts rms. The required
transformer input tapping is selected on the trans former
tag board,
