Product Description

Product Features

1.4U rack-mountable, portable design with a carrying handle and foot pads; the unit weighs just 13.7kg, making it easy to transport and install in a rack

2.7-step power adjustment, adjustable from 100 W to 5 kW, with a minimum increment of 100 W; settings: 100 W, 200 W, 200 W, 500 W, 1 kW, 1.5 kW, 1.5 kW

3. Forced air cooling, featuring two 12038 fans, ensuring long periods of continuous operation

4. The digital display panel shows voltage, current and power in real time, whilst the button controls are simple and intuitive to use.

5. Multiple safety features: overheat alarm, overvoltage protection and emergency stop function; protection rating IP20; for indoor use only

Application Scenarios

  • Factory ageing tests for power supplies, inverters and UPS (uninterruptible power supply) units

  • Performance testing and load testing of energy storage inverters and AC power modules

  • AC-side simulated load testing of generator sets and charging points

  • Laboratory product research and development, type testing, and calibration of power supply equipment

  • Maintenance and servicing of electrical equipment, discharge testing, and simulation of real-world load conditions

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.
