Power supply
A power supply is an electrical device supplying power to a load. Its main purpose is to convert current from a source to the correct voltage, current, and frequency to power the load, so they're also called electric power converters.

The "630" of 6306A DC power supply stands for 6000 (6 with '3' zeros) and "6A" means 6 ampere for its max current.

[2], [5] The 6000 Series or 6306A series is a dual-channel-output DC power supply.
Its features are:
Twin power output with tracking function for automatic selection of parallel or serial connection
Short-circuit protection against external input while providing constant voltage and constant current
Allows serial or parallel connection with the same power supply model
5V/5A constant-voltage output
Its 4 screens (2 for voltage and 2 for current) are for real-time monitoring and control of many simultaneous parameters
Most high-end lab power supplies use multiple digital displays to show critical parameters without needing to switch modes.
The 4 screens are often:
Set voltage (V-SET): the target output voltage
Actual voltage (V-OUT): the real-time measured voltage
Set current (I-SET): the configured current limit
Actual current (I-OUT): the real-time measured current
[4] "Slave" and "Master" refers to a control relationship between many units:
Master: main unit controlling 1+ secondary units.
Slave: The secondary unit(s) following commands of the "master".
A 6306A Series has a "Slave" (left) knob that does nothing and a Master (right) knob controlling both voltage analog.

Dual power supply
Dual power supply
A dual power supply is a supply that outputs 2 different (often symmetrical; +12V and -12V) outputs via 1 input and a common gnd. It's often used for OP amps and audio tools, allowing signals to go above and below the ground reference. It differs from redundant dual-source supplies used in servers.
[8] If we switch a voltage source's orientation to negative polarity for many circuits, the circuit may not work, but some need negative voltage and some can't work without it.
E.g., An electronic device that often use negative voltage is a transistor. Dual OP amps need both positive and negative voltages.
To create a dual voltage config., we can use use 2 batteries (of e.g., 9 V) in series. One positive and one negative will be connected in series. Connect the middle terminals using an alligator clamp. For the two remaining terminals, connect an alligator clamp. One for each side.
