SORENSEN DCR40-25B 40V 50A Single Output DC Power Supply

The Sorenson DCR40-25B 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 40 Vdc. Output Current (40 C): 25 A. Constant Voltage Regulation: 20 mV. Constant Current Regulation: 63 mA. Constant Voltage Ripple (PARD): 90 rms/mV. Constant Current Ripple (PARD): 56 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 ± 1% 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 DCR40-25B. 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.

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

Dynamic range
Dynamic range the ratio of a specified maximum level of a parameter, such as power, current, voltage or frequency, to the minimum detectable value of that parameter.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.
