What are the precautions for using a three-phase program-controlled precision test power supply?
The three-phase program-controlled test power supply is mainly used for measurement, inspection, and high-precision standard signal sources. Below, GDZX will introduce the precautions of three-phase program-controlled precision test power supply for everyone.
1. The three-phase program-controlled test power supply must be used in strict accordance with the safety specifications under the conditions specified in the instructions to ensure the safety of equipment and personnel.
2. The voltage output must not be short-circuited between phases, otherwise the internal power devices of the device may be burned.
3. Although the three-phase program-controlled test power supply has overload and short-circuit protection, it is still recommended that users work below the rated power value to ensure the long-term stable operation of the device (the voltage output cannot be short-circuited, and the current cannot be open-circuited).
4. The frequency of phase C of the three-phase program-controlled test power supply is individually adjustable. When the frequency of phase C is inconsistent with the phases of A and B, the phase measurement loses its meaning.
5. When the three-phase program-controlled test power supply issues an audible alarm, the power supply should be turned off in time to avoid affecting the service life of the device.
6. Do not touch the voltage output terminal of the device with your hands to avoid electric shock.
7. If there is a problem with the equipment, please notify our company for repair in time. Personnel without professional training must not disassemble the equipment.
8. Only 5A / 221V standard fuses can be used at the power input end of the device.
9. When using this device, please ensure that the chassis is reliably grounded to ensure personal safety. The grounding bolts on the back of the device can be used for safe grounding, or the neutral line of the three-pronged power cord has been reliably connected to the ground loop.
