BK PRECISION 1761 Triple Output DC Power Supply

The B+K Precision 1761 Triple Output DC Power Supply is a high quality, general purpose dc power source. It provides two “main” supplies with a 0-35V volt dc output and a “third” output with a 2-6.5A volt dc output. The “main” V supplies are adjustable with both coarse and fine voltage controls for precise settability and are capable of current output of 0-3 amps. The “third” supply has a current output of 0-5 amps, allowing it to handle extensive digital logic circuitry. Two large panel-mounted LED meter displays can monitor either the output current or output voltage of each supply. The two “main” volt supplies can be operated independently or in one of two tracking modes. In the series tracking mode, the “B” Supply tracks from 5% to 100% of the voltage of the “A” Supply. Maximum current setting of the two supplies can still be set independently when in the series tracking operating mode. In the series tracking mode the “A” and “B” supplies are connected in series, allowing a single output of 0-70 V at up to 3 amps. In the parallel tracking mode, the two supplies are connected together in parallel, allowing a single 0-35 V output at up to 6 amps. Both “main” volt supplies may be used in constant voltage or constant current applications. The crossover from constant voltage to constant current modes is smooth and automatic. LED’s indicate the “CV” (constant voltage) or “CC” (constant current) mode of operation. Specifications “A” AND “B” supplies. Output Voltage Range: 0 V to 35 V. Output Current Limit Range: 0.1 A (5%) to 3 A. Load Regulation (Constant Voltage): =0.01% + 3 mV. Ripple (Constant Voltage): =1 mV RMS. Load Regulation (Constant Current): =0.2% + 3 mA. Line Regulation 108 - 132 V (Constant Current): =0.2% + 3 mA. Ripple Current (at 108 V for Constant Current): =3 mA RMS. Tracking (Series) Accuracy: ±0.2% + 10 mV. Panel Meter Accuracy (Volts): ±0.5% + 9 digits. Panel Meter Accuracy (Current): ±0.5% + 9 digits. Specifications “Third” supply. Output Voltage Range: 2 V to 6.5 V. Load Regulation (Constant Voltage)“Third”: =10 mV (0 to 5 A load). Line Regulation 108 - 132 V (Constant Voltage): =10 mV. Ripple and Noise: =2 mV RMS.

Crest Factor
Crest factor or peak-to-average ratio (PAR) is a measurement of a waveform, calculated from the peak amplitude of the waveform divided by the RMS value of the waveform

Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Phase Noise
Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Phase noise (L(f)) is typically expressed in units of dBc/Hz, representing the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets from the carrier.

Sensitivity is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.
