The Instek SPD-3606 triple-output switching 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 amount 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 switching-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.
