Page 11: Control Descriptions
The AX Series Power Supplies provides the ability to limit the current output. When the “limit” is reached, the power supply will switch to “current” regulation to ensure the current output and drops the voltage regulation. Setting a Current Limit: • Short the output terminals, and adjust the current to the desired limit (you may need to have a little voltage for the current to flow). The value of current flow will be displayed on the appropriate dis- play. • Turn the voltage output off and connect to the sample. As the volt- age is increased, if the current reaches the set limit, the “LIMIT” LED will turn on, and the current will no longer increase. • The current limit may be overridden simply by increasing the cur- rent output manually.

• Set the MASTER Voltage to 10.0V • Set the SLAVE to 30% (3.0V) • Turn the Tracking switch to ON • The MASTER will display 10.0V and the SLAVE will display 3.0V • As the MASTER is increased or decreased, the SLAVE will track @ 30% • During Tracking, the SLAVE LED displays the actual SLAVE output voltage DC Power Supply Models AX501, AX502 and AX503 ShopAEMC www. .com 1.888.610.7664 Shop for AEMC products online at:... -

Page 17: Operation
WARNING: When the instrument is open, some of the internal capacitors may be dangerous, even once the instrument has been powered down. In the event of faults or abnormal constraints, turn the instrument OFF and do not use it until it has been checked. Operating Instructions • Check the label at the rear of the power supply to make sure that the instrument is set to the AC line voltage compatible with your setting. • Connect the AC power cord to the supply. • No connections should be made before powering up. • Start up the power supply by pushing the Power On/Off button ON. • To turn OFF the instrument, unplug the leads and push the Power On/Off button OFF.

Page 18: Using Independent Outputs
(see Fig. 4): • Set the “TRACKING” switch to the OFF position. • Set the 2 power supplies (MASTER and SLAVE) to the same output voltage value. • Link the “+” terminals together and the “–” terminals together using short leads. • Connect one of the two “+” terminals and one of the two “–” termi- nals to the circuit to be powered.

2.5A max (see Fig. 6): Procedure: (for serial number > 105500MAV) • In sequence (power supply a then b), adjust the "current" potentiometers to define identical limit currents. • Set the 2 Voltage potentiometers of the slave to the maximum (around 30.5V). • Press the "TRACKING" button ("ON", LED lit). When set to "ON", a series connection between the "-" terminal of the "MASTER" power supply and the "+" terminal of the "SLAVE" power supply is set. • The "MASTER" source is on the left (a); set the required initial voltage, adjust it to the desired voltage. • The "SLAVE" source is on the right (b).

Page 20: Use Of 2.7V To 5.5V (5A) Power Supply
• Set the required voltage between 2.7V and 5.5V using the adjustment control. • For “FINE” adjustment, connect these terminals to a multimeter (appropriate range). • If the output current reaches the 5A limit current value, the “LIMIT 5A” LED comes on, the power supply automatically switches to “current” regulation mode and the voltage is no longer regulated. NOTE: This output is designed to power logic circuits at 3 or 5V with consumption up to 5A.

Page 21: Maintenance
Wipe with a clean dry cloth. Make sure it has completely dried before use. • Do not use abrasives or solvents. Storage • To ensure proper operation, wait for the instrument to return to normal measuring conditions if it has been stored in extreme envi- ronmental conditions for a long period of time. An abrupt change in the ambient temperature may lead to conden- sation inside the instrument and cause short circuits. Let the power supply stabilize in temperature before use.
