Oscillator Sync Output
Connection:
Max Off State Voltage:
Collector Current:
DROPOUT VOLTAGE
The load will cease to conduct if the applied voltage falls below the Dropout Voltage setting;
active in all modes except Constant Voltage. The Dropout Voltage setting is also the threshold for
the Slow Start facility and acts as an offset voltage in Constant Resistance mode.
Setting Accuracy:
Slow Start
If the Slow Start switch is engaged, the load will not conduct any current until the source voltage
reaches the Dropout Voltage setting; it will then ramp up to the Level setting at a rate determined
by the settings of the Slew Rate controls.
