GW Instek PSP-405 LCD Display Programmable Switching DC Power Supply, 0-40 Volts, 0-5 Amps, 200W

Brand: GW Instek

Features:

• Switching power supply unit provides a constant source of DC voltage and current for powering and testing electronic devices
• LCD shows voltage and current reading simultaneously and is readable in low light
• Voltage, current, and power limits provide greater control over output
• %+ and %- modes modify the output by a preset percentage
• RS-232C interface connects to a computer for remote control with SCPI commands

Details: This Instek PSP series single-output programmable 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 one output that supplies adjustable voltage and current for a variety of applications. The LCD shows the voltage and current reading simultaneously along with the setting parameters, and the display is readable in low light. The PSU has an RS-232C interface for connecting to a computer (cables sold separately). Software download is included for remote control and testing applications. A lock feature disables the front-panel keypad to help prevent accidental input. A power cord with a three-prong plug is included for connecting the PSU to a grounded outlet, and test leads are included. A built-in cooling fan with three speeds helps prevent overheating. Overcurrent and overvoltage protection and an output on/off switch help prevent damage to the PSU and the device under test. This Instek PSP series power supply unit is offered with a choice of rating current and voltage and resolution and program accuracy.

H is the vertical distance from lowest to highest point, W is the horizontal distance from left to right, and D is the horizontal distance from front to back.
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.
