• Manufacturer: C&D Technologies.

Start-Up Threshold and Undervoltage Shutdown
Under normal start-up conditions, devices will not begin to regulate until the
ramping-up input voltage exceeds the Start-Up Threshold Voltage (35V for
"D48A" models). Once operating, devices will not turn off until the input volt-
age drops below the Undervoltage Shutdown/Lockout limit (34V for "D48A"
models). Subsequent re-start will not occur until the input is brought back up to
the Start-Up Threshold. This built-in hysteresis obviously avoids any indetermi-
nate on/off situations at a single voltage.

Start-Up Time
The V
ing input voltage crosses the turn-on threshold point and the fully-loaded output
voltage enters and remains within its specified accuracy band. Actual measured
times will vary with input source impedance, external input capacitance, and the
slew rate and final value of the input voltage as it appears to the converter.
On/Off Control with the nominal input voltage already applied to the converter.
The specification defines the interval between the time at which the converter
is turned on and the fully-loaded output voltage enters and remains within its
specified accuracy band.
