SORENSEN DCR300-3B 300V 3A Single Output DC Power Supply

The Sorensen DCR300-3B high power programmable power supply has an input SCR controlled regulator which provides unparalleled reliability along with regulation and transient response performance suitable for nearly all burn-in and test applications. It has remote voltage and resistance programming in voltage and current modes. Adjustable current limiting (overload/short circuit protection) with automatic recovery and overvoltage protection with crowbar standard. Specifications. Output Power: 0 to 300 VDC, 3.0 A. Constant Voltage Ripple (PARD) (mV rms): 700. Constant Currennt Ripple (PARD) (mA rms): 7. Temp. Coeff Voltage: 45 mV/C, 0.9 mA/C. Programming Constants: 40 ohms/Volt, 133 ohms/Amp. Signal (Volt In/ Volt out): 1/30. Efficiency: 82 % (typ). Voltage Regulation: 0.03% with load change. Voltage resolution: 0.05% of Eo max. (typical). Transient Response: 50 ms (typical) to return to ± 1% band for step load change of 50 to 100% of full load. Current Regulation: 0.25% with 0 to 95% compliance-voltage change and ± 10% line voltage change combined. Current resolution: 0.05% of Io max. (typical). Current Drift (% Io max): 0.15% (typical).

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

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.
