SORENSEN DCR20-25B 20V 25A Single Output DC Power Supply

The Sorenson DCR20-25B Power Supply incorporates a single phase input SCR controlled regulator providing high efficiency and fully adjustable output power. It has excellent voltage and current regulation with automatic crossover. Features. Panel lights indicate operating mode. Remote voltage and resistance programming in voltage and current modes. Adjustable current limiting (overload/short circuit protection) with automatic recovery. Overvoltage protection standard. Specifications. Output Voltage: 0 to 20 Vdc. Output Current (40 C): 25 A. Constant Voltage Regulation: 10 mV. Constant Current Regulation: 63 mA. Constant Voltage Ripple (PARD): 65 rms/mV. Constant Current Ripple (PARD): 82 rms/mA. Voltage Regulation (Constant Voltage Mode): 0.05% or 10 mV, whichever is greater. Temperature Coefficient: 0.015%/C of Eo max. Stability: 0.1% Eo max for 8 hours after 30 minute warm-up. Remote Sensing: Maximum drop per load lead should not exceed 5% of Eo max. or 3 V, whichever is smaller. Transient Response: 50 ms (typical) to return to ± 2% band for step load change of 50 to 100% of full load. Current Regulation (Constant Current Mode): 0.25% of 10 max. line and load combined. Temperature Coefficient: 0.03%/C. of lo max. Stability: 0.15% of 10 max. for 8 hours after 30 minute warm-up.

*This is a Web introductory price for one calibration of the SORENSEN DCR20-25B. 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.
