Set-Up and Operation

Constant Voltage

Operations

Press the constant key (labeled K) until the LED indicating "Volts" is
illuminated. Each time the constant key is pressed, the EC300 will display
the last saved setpoint value for that particular mode. Use the UP and
DOWN arrow keys to change the setpoint to the desired value (10-300
volts). The EC300 will not allow setting a voltage setpoint outside of the
allowed range. Press and hold either arrow key to quickly change the
setpoint.

The limit parameter, in this case current, is normally set to the power
supply maximum value of 400 mA. To set a lower limit value, press the Set
key until the LED indicating "mAmps" is illuminated. Use the UP and
DOWN arrow keys to change the limit to the desired value (4-400 mA).
The EC300 will not allow setting a current limit outside of the allowed
range.

In addition, the EC300 will never exceed the maximum power output
specification of 75W. When starting a run, the power supply calculates a
maximum limit parameter, above which the power supply maximum
power output rating would be exceeded. If this value is lower than the
limit setpoint entered, the EC300 will use this lower limit parameter.

Press the constant key (labeled K) until the LED indicating "Amps" is
illuminated. Each time the constant key is pressed, the EC300 will display
the last saved setpoint value for that particular mode. Use the UP and
DOWN arrow keys to change the setpoint to the desired value (4-400
mA). The EC300 will not allow setting a current setpoint outside of the
allowed range. Press and hold either arrow key to quickly change the
setpoint.

The limit parameter, in this case voltage, is normally set to the power
supply maximum value of 300 volts. To set a lower limit value, press the
Set key until the LED indicating "Volts" is illuminated. Use the UP and
DOWN arrow keys to change the limit to the desired value (10-300 volts).
The EC300 will not allow setting a voltage limit outside of the allowed
range.

In addition, the EC300 will never exceed the maximum power output
specification of 75W. When starting a run, the power supply calculates a
maximum limit parameter, above which the power supply maximum
power output rating would be exceeded. If this value is lower than the
limit setpoint entered, the EC300 will use this lower limit parameter.
