Variable isolated 0 to 150 VAC 2A (1653A) continuous output Displays voltage or current readings Isolation transformer to eliminate shock hazard while servicing "hot chassis" equipment 120VAC, 60Hz Input This B&K Precision variable AC power supply provides a source of AC voltage and current for powering and testing electronic devices in research, medical, laboratory, production, and educational applications. The power supply unit (PSU) supplies continuously variable voltage or current. The unit has a built-in isolation transformer that reduces risk of shock when working with hot-chassis equipment. A digital meter shows output voltage and current readings. An input fuse helps prevent damage to the PSU or connected equipment due to overload. This B&K Precision variable AC power supply is offered with a choice of number of outputs, rating current range, meter scale, leakage, dimensions, and weight. Specifications Maximum voltage output 150VAC Meter accuracy, voltage and current + or – 5% of full scale Voltage/current sensing Sine wave average, calibrated in root mean square Output isolation Leakage less than 0.1mA (milliamp) at 25 degrees C and 50% relative humidity Power requirements 120VAC, + or – 10% at 60Hz Operating temperature 0 to 40 degree C 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.
