Product Description & Reviews
The B&K Precision single-output programmable switching benchtop 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 LED screen shows the voltage and current reading simultaneously, and the display is readable in low light. Analog rotary encoder knobs on the front panel provide fine and coarse adjustment of the voltage and current output. The PSU's internal memory can store up to three output settings for future recall. The PSU can be controlled remotely via the USB interface on the rear panel, which can be connected to a computer (USB cable included), or the analog remote control terminal on the rear panel, which can be connected to a variable DC voltage source or variable resistor (remote control connector included). A software CD is included for remote control and testing applications. A power cord with a three-prong plug is included for connecting the PSU to a grounded outlet. A built-in cooling fan with three speeds helps prevent overheating. Overcurrent and overvoltage protection help prevent damage to the PSU and the device under test. This B&K Precision power supply units is offered with a choice of rating current and voltage, full load input current, efficiency, and tracking overvoltage protections.SpecificationsNumber of outputs1Load regulationVoltage: Less than or equal to 50mV (millivolts); Current: Less than or equal to 100mA (milliamp)Line regulationVoltage: Less than or equal to 20mV; Current: Less than or equal to 50mARipple and noiseLess than or equal to 5mV RMS (root mean square), or less than or equal to 50mV peak to peakRipple currentLess than or equal to 30mA RMSMeter accuracy+ or – 2% + 3 countsTransient response time1.5ms (milliseconds)Switching frequency100 to 120kHzPower requirements100 to 240VAC at 50 to 60 HzOperating temperature and humidity32 to 104 degrees F/0 to 40 degrees C, less than or equal to 80% relative humidityStandards metEuropean Conformity (CE) markingWeight2.4kg/5.2lb.Dimensions90 x 200 x 208mm/3.5 x 7.9 x 8.2 inches (H x W x D)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.B&K Precision manufactures test and measurement instruments for research and development, production-line testing, and electronic field service applications.
