SORENSEN SRL20-25 20V 25A Single Output DC Power Supply

The Sorenson SRL20-25 Power Supply incorporates all the benefits of a linear series pass design with preregulation to provide an additional bonus of high efficiency and outstanding performance. It has excellent voltage and current regulation with automatic crossover. Features. Remote voltage and resistance programming in voltage and current modes. Unique quick set and check of built-in overvoltage protection can be monitored and adjusted on front panel. Set point can be adjusted without removing load or ac power. No overshoot at turn-on, turn-off or power failure. Specifications. Output Voltage: 0 to 20 Vdc. Output Current (40 C): 25 A. Constant Voltage Mode Regulation: 0.01% or 2 mV. Constant Voltage Mode Ripple (PARD): 300 µV (rms 10 Hz to 7 MHz), 20 mV (p-p 7 Hz to 25 MHz). Constant Voltage Mode Resolution (Typ.): 5 mV. Transient Response Time: 150 µs (typical). Temperature Coefficient: 0.01% + 0.2 mV/DC. Resistance Programming: 200 ohms per volt standard; (adjustable to 1000 ohms per volt through the use of externally added components). Stability: 0.025% + 0.5 mV for 8 hours after 30 minute warm-up time with constant line, load and operating temperature. Remote Sensing: 1 V maximum drop per load lead (rear terminal connection). Constant Current Mode Regulation: 0.02% + 4 mA. Constant Current Mode Ripple (PARD): 10 mA (rms 10 Hz to 7 MHz). Constant Current Mode Resolution (Typ.): 3.75 mV. Current Programming: 1000 ohms programs full rated output. Minimum Current: Adjustable down to zero. Temperature Coefficient: 0.01% +2 mA per C. Stability: 0.03% + 10 mA (typical for 8 hours after 30 minute warm-up time with constant line, load, and ambient operating temperature).

*This is a Web introductory price for one calibration of the SORENSEN SRL20-25. 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
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.
