7. Fitted with castors for easy on-site repositioning
Application Scenarios
Factory ageing and performance testing of UPS units, inverters and power modules
Load testing of the output from the variable-frequency power supply and shore power supply
Research, development and commissioning of laboratory power supplies; type testing
Sampling tests on production lines, batch ageing verification
Common Questions & Answers
Q1: Can 110V and 220V be used at the same time?
A: No, as it is a switching design, it only supports operation at one voltage at any given time.
Q2: What is the maximum power input?
A: The maximum combined power at full load is 10.5 kW; prolonged operation in excess of the rated power is not recommended.
Q3: Can it be used outdoors?
A: Protection rating IP20; for use in dry, well-ventilated indoor environments only; not suitable for outdoor use.
Q4: When is the overvoltage protection triggered?
A: Overvoltage protection is automatically activated when the voltage reaches 1.1 times the rated voltage.
Q5: Does it support continuous operation over long periods?
A: Under rated operating conditions, it can operate continuously 24 hours a day, 7 days a week, and is equipped with comprehensive cooling and protection mechanisms.
