two volt-meters two ampere-meters
1 resistive load: 200 Ω / 50 W
One NCP5106B Evaluation Board
Test Procedure:
1. First of all check if you need or not the jumper #2 (J2 on the board close
the diode bridge). This jumper must be removed in case of European mains
(230 Vac input voltage) and have to placed in case of US mains (110 Vac).
This jumper is used to build a voltage doublers just after the bridge diode
in case of US mains input voltage range.
2. Connect the test setup as shown above:
• AC source
• Voltmeter and Ampere meter on the load
• Load on the output
3. Apply 230 Vac if European mains or 110 Vac for the US mains on the input
connector.
