The rack mount kit is needed for rack mounting of the E3630A power supply.
Description
This constant-voltage/current-limiting triple output power supply combines two
0 to ±20 V tracking outputs rated at 0.5 amps with an additional single output
that is rated at 0 to 6 volts and 2.5 amps. The +20 V and –20 V tracking outputs
can also be used in series as a single 0 to 40 V 0.5-amp output. Connections to
the supply's output and to chassis ground are made to binding posts on the front
panel. The supply's three outputs share a common output terminal, which is
isolated from chassis ground so that any one output terminal can be grounded.
All outputs are protected against overload and short-circuit damage. The ±20 V
outputs are protected by circuits that limit the output current to 110% of its
nominal maximum. The overload protection circuit for the +6 V output has a
current foldback characteristic that reduces the output current as an overload
increases until only 1 amp flows through a short circuit. The 6 V output current
limit depends on the output terminal voltage and varies linearly between
2.75 amps at 6 volts and 1 amp at zero volts.
All controls, digital meter, and output terminals are located on the front panel.
One voltage control sets the 0 to 6 V and another sets the voltages of the 0 to
+20 V and 0 to –20 V outputs simultaneously.These dual tracking outputs are
made more versatile by providing a tracking ratio control in addition to the usual
voltage control. With the tracking ratio control turned fully clockwise to its "fixed"
position, the dual outputs have a fixed 1:1 tracking ratio. As the ±20 V voltage
control is adjusted, the voltage of the negative supply tracks the positive output
within ±1%. Turning the tracking ratio control away from its fully clockwise
position switches the dual tracking outputs into a variable tracking ratio mode. In
this mode the voltage of the negative output can be set lower than that of the
positive output. The tracking ratio control allows the negative supply's output to
be set to any value between a maximum that is within ±5% of the positive supply's
output and a minimum that is less than 0.5 volts.
