BK PRECISION 1670A Triple Output DC Power Supply

The B+K Precision 1670A is a general purpose triple output DC power supply. Their main outputs are versatile constant voltage or constant current regulated power source that is variable from 0 to 30 volts and 0 to 3 amps. An indicator lights in the constant current mode, and serves as an overload indicator in the constant voltage mode. The main output voltage and current are continuously monitored by two digital LCD meters with resolution of 0.1 volt and 0.01 amp. Specifications. Number of Outputs: Three (1 variable, 2 fixed). Range: 0-30 V / 0-3 A (variable), 12 V ±5% / 500 mA (fixed), 5 V ± 5% / 500 mA (fixed). Constant Voltage Operation Line Regulation: <= 0.05% + 10 mV (main), <= 1% (fixed output). Constant Voltage Operation Load Regulation: <= 0.05% + 10 mV (main), <= 1% (fixed output). CV Ripple & Noise: <= 5 mV rms. Constant Current (CC) Adjustable Current Range: 5% to 100% (Main). CC Line Regulation: <= 0.4% + 10 mA. CC Load Regulation: <= 0.4% + 10 mA. CC Ripple & Noise: <= 10 mA rms. Display: 3-digit LCDs. Voltmeter Resolution: 0.1 V. Voltmeter Accuracy: ±(1% reading + 2 digits). Ampmeter Resolution: 0.01 A. Ampmeter Accuracy: ±(1% reading + 2 digits). Overload Protection: Current limiting, Reverse polarity, Overvoltage, Short circuit.

*This is a Web introductory price for one calibration of the BK PRECISION 1670A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
