Q1: What is this AC variable frequency power supply for?
A: It is industrial precision test equipment for home appliance testing, electronic certification, lab research, motor aging and export commodity inspection. It simulates global grid voltage and frequency for worldwide testing standards.

Q2: What voltage and frequency can you output?
A: Standard output: 0–500V adjustable, 40Hz–499.9Hz adjustable. Support single/three-phase and high-power customization to fit all country power standards.

Q3: Can it run 24 hours continuously?
A: Yes. Industrial full-load design with professional heat dissipation system, stable for 24/7 non-stop production line and laboratory long-time testing.

Q4: How precise is your power output?
A: Voltage accuracy ±0.1%FS, frequency accuracy ±0.01Hz, THD＜1%. Pure sine wave output ensures accurate and repeatable test data.

Q5: Does it work with unstable local power grid?
A: Yes. Built-in anti-interference and surge protection module. It filters grid noise and stabilizes output, suitable for unstable power areas in Southeast Asia, Africa and South America.

Q6: What safety protection do you have?
A: 8 protections including overload, short circuit, overvoltage, overcurrent, overheat and lightning protection. Auto power-off alarm protects machine and test samples safely.

A: Yes. Customizable power range, special voltage/frequency, multi-language panel, remote control and data recording to meet different industrial needs.

Q8: What is your warranty & overseas service?
A: 1-year global warranty + lifelong technical support. 24h online English guidance, free English manual and operation videos.

Q9: Do you support export customs clearance?
A: All products pass CE & ISO9001 certification. We provide full export documents for smooth customs clearance.

• Place indoors in dry, clean and ventilated conditions, working temperature: 0℃–40℃
• Reserve over 30cm space around the machine for heat dissipation
• Reliable grounding required for operation safety

• Check input & output wiring to avoid wrong connection
• Run 5–10 minutes no-load test for first use to confirm stable status
• Store common test parameters for fast batch testing

• Avoid frequent instant start-stop for motor and inductive loads
• Observe machine temperature and running status during long-time operation
• Match voltage regulator if local grid fluctuates heavily

• Clean fan and vent dust every 1–3 months
• Check terminal connection tightness every half year
• Cover dust cover and power off for long-term idle use
