•
Prior to connecting the DC input source VIN, it is advisable to limit the source current from VIN to 2 A
maximum. Make sure VIN is initially set to 0 V and connected to J2 as shown in
maximum. Make sure VIN is initially set to 0 V and connected to J2 as shown in
•
Connect a current meter A1 between VIN and J1 to measure the input current.
•
Connect a voltmeter V1 at TP1 (VIN) and TP2 (GND) to measure the input voltage.
Output Connections:
•
Connect Load to J2 and set load to constant resistance mode to sink 0 A
DC
before VIN is applied.
•
Connect a voltmeter V2 at TP7 (VOUT) and TP8 (GND) to measure the output voltage.
Other Connections: Place a fan as shown in
