3.2.1 Test Setup Requirements

Safety: This evaluation module is not encapsulated and there are accessible voltages that are greater than 50VDC.

Isolation Input Transformer: An appropriately rated 1:1 isolation transformer shall be used on the inputs to this EVM and be constructed in a manner in which the primary winding are separated from the secondary windings by reinforced insulation, double insulation, or a screen connected to the protective conductor terminal.

WARNING:
  • If the user is not trained in the proper safety of handling and testing power electronics, then please do not test this evaluation module.
  • While the EVM is energized, never touch the EVM or the electrical circuits, as the EVM or the electrical circuits can be at high voltages capable of causing electrical shock hazard.
  • Caution: Hot surface. Contact can cause burns. Do not touch!
  • Read this user's guide thoroughly before making test.

Voltage Source: Isolated AC source or variable AC transformer capable of 264VRMS and capable of handling 100W power level.

Voltmeter: Digital voltage meter

Power Analyzer: Capable of measuring 1mW to 100W of input power and capable of handling 264VRMS input voltage. Some power analyzers may require a precision shunt resistor for measuring input current to measure input power of 5W or less. Please read the power analyzer’s user manual for proper measurement setups for full power and for stand-by power.

Oscilloscope:

  • 4 Channel, 500MHz bandwidth.
  • Probes capable of handling 600V.

Output Load: Resistive or electronic load capable of handling 130W at 20V.

Recommended Wire Gauge: Insulated 22AWG to 18AWG.
