FAQ |
|---|
| Q1: Why is low THD important for sensitive electronics? |
| A: High harmonic distortion can cause measurement errors, introduce noise into audio signals, or affect the operation of precision analog circuits. A clean power source ensures the device under test is evaluated on its own merits, not on power quality. |
| Q2: Can this power supply simulate international grid voltages? |
| A: Yes, with adjustable voltage up to 300V and frequency from 45 to 500Hz, it can replicate most world power standards (115V/60Hz, 230V/50Hz) and beyond. |
| Q3: How does the isolation transformer benefit my application? |
| A: It breaks ground loops, reduces common-mode noise, and provides safety isolation, essential for test setups involving sensitive measurement equipment. |
| Q4: Is it suitable for continuous operation? |
| A: Yes, it is rated for 24/7 continuous duty at full rated power within specified operating conditions. |
| Q5: What communication options are available for automated testing? |
| A: Standard RS232 and RS485 Modbus interfaces allow remote control and monitoring via PC or PLC. |
