- Sw power supply unit provides a constant source of DC voltage and current for powering and testing electronic devices.
- Two outputs with dual ranges supply adjustable voltage up to 30VDC and current up to 6 amp, or voltage up to 60VDC and current up to 3 amp.
- Third output supplies adjustable voltage of 0.1V to 5VDC and fixed current of 3 amp.
- High power-conversion efficiency reduces the unit's energy consumption.
- Simultaneously displays current and voltage for outputs.
The Instek SPD-3606 triple-output sw DC power supply unit
provides a constant source of DC voltage and current for powering
and testing electronic devices. The power supply unit (PSU) has
two dual-range outputs that each provide DC voltage from 0 to 30V
and current from 0 to 6 amp, or DC voltage from 0 to 60V and
current from 0 to 3 amp, with adjustable output. A third output
supplies an adjustable voltage between 0.1V and 5VDC and a fixed
current of 3 amp. The PSU's high power-conversion efficiency
reduces the unit's energy consumption. The PSU simultaneously
shows voltage and current readings for each output. The 0 to 30V
outputs can be connected in series to supply more voltage, or
they can be connected in parallel to supply more current. When in
tracking mode, one output can be set to supply a percentage of
the voltage of the second output. A built-in cooling fan with
three speeds helps prevent overheating. Reverse polarity,
overvoltage protection, and an output on/off switch help prevent
damage to the PSU and the device under test, and the unit
automatically selects between 115V and 230V line voltage.

Power supply units (also known as PSUs, AC power supplies, DC
power supplies, and battery eliminators) provide AC or DC voltage
to power or test devices such as tools, appliances, and
electronic components. The PSU draws energy from a line source
such as a wall socket and converts it to a constant, specified
a of voltage or current that is then outputted to a
connected device. In general, a power supply unit will be
classified as either a linear PSU (also known as a linear
regulation or line-frequency PSU) or a switched PSU (also known
as a sw-mode power supply, SMPS, or switcher). Typically,
a linear PSU has a simpler design and provides a faster transient
response time and less electrical interference and noise than a
switched PSU. A switched PSU is often smaller, lighter, and more
efficient than a linear PSU and generates less heat. The
transient response time of a PSU indicates how quickly the PSU
can resume the desired constant output after a sudden change in
input. Ripple voltage or current indicates how much unfiltered
noise and AC voltage or current is present at the output of a
filtered power supply operated at full load. The temperature
coefficient is the percent average change in output voltage per
degree centigrade of change in ambient temperature. Fuses,
current limiters, and other forms of overload protection can be
built into the PSU to help protect against voltage spikes or
short-circuiting.
