1. GENERAL DESCRIPTION
1. GENERAL DESCRIPTION.
The Model 71 power supply described in this manual is
designed for general purpose use in industry, laboratory,
radio station and school to supply power to electronic and
other equipment. The DC output voltages are electronically
regulated, are practically independent of normal line voltage
fluctuations and substantially free from hum and noise. The
high-voltage DC output is constant (within the specified
limits) from zero to maximum load and features a continuously-
variable voltage·control with an auxiliary vernier-control
for precise voltage adjustment. The DC bias-voltage output
is also continuously adjustable and is closely regulated for
line voltage variations. The following output voltages are
supplied:
Output #1: 0-500 VDC, 0-200 MA, regulated.
Output #2: 0-200 VDC, 0-50 VDC, bias output. Regulated
for line voltage variation.
Output #3: 6.5 VAC, 5A, unregulated.
Output #4: 6.5 VAC, 5A, unregulated.
The easy-to-read 3-1/2" panel meters permit monitoring
of output voltage and current. Magnetic circuit-breakers
provide convenient AC and DC overload protection. A time-
delay relay circuit protects the tubes during the initial
warm-up period. Sturdy, insulated binding-posts are
provided for front panel connections. A 5651 voltage
reference tube insures long time stability for operation.
Quality components, conservatlvély rated, guarantee long,
dependable trouble~free service.
