6218C Agilent DC Power Supply Used

Load Regulation:

• Constant Voltage: Less than 4 mV for a load current change equal to the current rating of the supply
• Constant Current: Less than 500 µA for a load voltage change equal to the voltage rating of the supply

Line Regulation:

• Constant Voltage: Less than 4 mV for ±10% change in the nominal line voltage at any output voltage and current within rating
• Constant Current: Less than 500 µA for a ±10% change in the normal line voltage at any output voltage and current within rating

Ripple and Noise:

• Constant Voltage: Less than 200 µV rms/1MV p-p (dc to 20 MHz)
• Constant Current: Less than 150 µA rms/500 u A p-p (dc to 20 MHz)

Temperature ranges:

• Operating: 0° to 55°C
• Storage: -40° to +75°C

Temperature Coefficient:

• Constant Voltage: Less than 0.02% + 1 mV output change per degree centigrade change in ambient following 30 minutes warm-up
• Constant Current: Less than 1 mA output change per degree centigrade change in ambient following 30 minutes warm-up

Stability:

• Constant Voltage: Less than 0.1% + 5 mV total drift for 8 hours following 30 minutes warm-up at constant ambient, constant line voltage, and constant load
• Constant Current: Less than 2.5 mA total drift for 8 hours following 30 minutes warm-up at constant ambient, constant line voltage, and constant load

Transient recovery time:

• Less than 50 µsec for output voltage recovery in constant voltage operation to within 15 mV of the nominal output voltage following a change in output current from 50% to 100% of the current rating of the supply and vice/versa

Overload protection:

• The current limit circuit protects the power supply for all overloads including a direct short circuit placed across the output terminals

Meter:

• The front panel meter can be used a s a voltmeter or an ammeter

Output controls:

• The voltage control and current control set desired output voltage/current. Meter switch selects voltage or current

Output Terminals:

• Three "five-way" output terminals are provided on the front panel. They are isolated from the chassis and either the positive or negative terminal may be connected to the chassis through a separate ground terminal

Cooling:

• Convection cooling is employed. The supply has no moving parts.

The Agilent 6218C is a low-cost CV/CC bench supply that is designed for general laboratory use and is equipped with front-panel mounted voltage and current controls, a combination volt/ammeter, and output binding posts. Output voltage and current are continuously variable, via multiple-turn controls from 0 to 15% above the maximum rated output. A switch selects either output voltage or current for display on the panel meter.

Load connections are made via three binding posts. Either the + or the - post may be grounded through an adjacent GND terminal or the supply may be operated floating at up to 300 volts above ground.

The 6218C can also be operated as a constant current source with 500 µA load regulation. The 6218C can also be connected in series or parallel.

The molded, impact-resistant case includes an interlocking feature for stacking several units vertically, thus minimizing bench space required for multiple supplies. Alternatively, up to three units can be mounted side by side in a 19" rack using the Rack Mount Kit 14521B. The 6218C measures 86 H x 133 W x 368 mm D (3.40" x 5.25" x 8").
