Common Questions & Answers
Q1: Can this load cabinet operate continuously for long periods?
A: It supports continuous 24/7 operation; the operating environment should be kept dry and well-ventilated, with the ambient temperature maintained between –10 and 50 °C.
Q2: What is the maximum input voltage?
A: Rated at 240 V AC; the overvoltage protection threshold is 1.1 times the rated voltage. Please do not operate the unit at voltages exceeding this threshold for prolonged periods.
Q3: What is the voltage of the cooling fan’s power supply?
A: Two 12038 fans are powered by 220 VAC and provide forced air cooling from front to back.
Q4: What does the protection rating IP20 mean?
A: Suitable for use in indoor environments; prevents fingers from coming into contact with internal live parts. It is not waterproof and must not be used in damp or wet conditions.
Q5: What is the lowest power setting?
A: The minimum step size is 100W; different power levels are achieved by combining settings.
