Common Questions & Answers
Q1: Can this load cabinet operate continuously for long periods?
A: Under standard operating conditions, it supports 4 hours of continuous online operation; however, 24-hour non-stop operation is not recommended. If long-term ageing testing is required, please enquire about a customised version.
Q2: What is the maximum supported voltage?
A: The rated voltage is 220 V AC; the overvoltage protection threshold is 1.1 times the rated voltage, not exceeding 242 V. Prolonged operation at voltages exceeding this limit is prohibited.
Q3: Can the current be adjusted?
A: Yes, it features a built-in multi-stage current switch; the settings can be combined to flexibly adjust the total load current.
Q4: What does protection rating IP20 mean?
A: Suitable for use only in dry indoor environments; it prevents fingers from coming into contact with live internal parts, but is not waterproof or dustproof, and must not be used outdoors.
Q5: Does it come with a BMS (Battery Management System)?
A: This model does not include a BMS; it is intended solely for ageing tests on standard AC loads and is not suitable for battery charge and discharge management applications.
