Product Operating Instructions

1
Before powering on, check the stored and transported switch power supply. Inspect for any damage during transit, such as loose screws, abnormal appearance, shaken off power cords/terminals, or dampness. Deal with any issues in a timely manner.
2
The local power switch controls the auxiliary power supply inside the machine. For safety, please add an air switch to the power input terminal to control the main input. Connect the ground and input power wires correctly according to the rear panel label. Verify that the input voltage matches the manual specifications.
3
The cooling fan is temperature-controlled and starts when internal temperatures exceed the threshold. Fan speed varies dynamically with output load conditions. Ensure the air inlets and outlets remain completely unobstructed during operation.
4
If the internal temperature reaches the overheating threshold, the machine shuts down automatically to prevent damage. It will resume operation automatically once the temperature drops.
5
When in use, ensure that dust, acid, corrosive gases, or substances in the air remain within normal limits. Avoid severe vibration, physical shock, rain, and direct sunlight.
6
Regular dust removal (using dry compressed air) will extend the service life and reliability of the equipment. Do not open the casing to perform this maintenance due to internal high voltage.
7
If stored idle for over 6 months, place it in a dry, ventilated room, and power it on for at least 30 minutes to ensure optimal component maintenance.
8
Warning: Only connect to powered load equipment after the initial power-on test is normal and error-free.
9
Troubleshooting: If operation seems abnormal, turn off the stabilized power switch immediately. Inspect all external connections, screws, switches, and knobs. Do not disassemble the casing yourself due to hazardous high voltage inside. Contact support promptly for professional assistance.

Frequently Asked Questions (FAQ)

Q: Does the power supply include overvoltage, overcurrent, overheating, and short circuit protection?
A: Yes, all of these safety protection mechanisms are fully integrated into the system.
Q: Is there reverse polarity protection available?
A: Reverse protection can be integrated as an optional, customized feature upon request.
Q: Can this device run continuously at 100% full power load?
A: No. For sustained reliability, the power supply must run with excess capacity. Continuous operations are highly recommended below 80% of the maximum capacity.
Q: How convenient is it to adjust both voltage and current?
A: It is highly convenient. Both parameters can be adjusted easily and precisely using the independent dual knobs on the control panel.
Q: Is this a fully isolated high-power supply unit?
A: Yes, the power supply is designed and manufactured with a fully isolated structure.
Q: What is the output voltage regulation range?
A: The output voltage is fully adjustable, starting from 1V.
