Product Description

Product Features

  • Dual-mode load

    Supports switching between R-load (resistive load) and RCD-load (resistive-capacitive load), and is compatible with both three-phase four-wire AC400V and single-phase AC230V voltage modes; rated capacity: 200 kW/200 kVA for three-phase and 67 kW/67 kVA for single-phase; power levels are step-adjustable.

  • High-precision load output

    Resistance accuracy: ±3%; power factor: adjustable to 0.71; the display intuitively shows key parameters such as voltage, current, power, and power factor; display accuracy: Class 0.5

  • Multiple security layers

    Equipped with overvoltage, overcurrent, and overheating fault alarms, as well as emergency stop protection; supports local touchscreen control combined with RS485 remote communication control, facilitating the integration of the device into automated testing systems.

  • Continuous and stable operation

    Forced air cooling with a top-in, bottom-out variable-speed fan; supports continuous online operation 24/7; the resistive design ensures a service life of 15 years.

Application Scenarios

  • Energy storage converters, UPS (Uninterruptible Power Supply) systems, factory aging tests for generator sets, load-based calibration

  • Photovoltaic inverters and bidirectional power supply equipment – performance, overload, and aging tests

  • Power supply equipment and charging pile power module – simulated load and discharge testing

  • The Power Equipment Research Laboratory and a third-party testing agency conducted load simulation tests.

Common Questions & Answers

Q1: Can the three-phase and single-phase modes be switched freely?

A:The system can be switched between modes; in single-phase mode, the maximum power is only one-third of that in three-phase mode – overpower operation is not permitted; the maximum allowable voltage is 1.1 times the rated voltage.

Q2:What is the difference between an R-load and an RCD-load?

A: R is treated as a pure resistive load; RCD is treated as a resistive-capacitive composite load, which can simulate various power factor operating conditions. The two modes require switching operation and cannot be enabled simultaneously.

Q3:Can the equipment operate continuously 24/7 without downtime?

A: Supports continuous 24/7 online operation; however, ensure the environment is dry and well-ventilated, with no blockage at the air intake or exhaust vents; the ambient temperature should be maintained within the range of 10–50°C.

Q4: How to perform remote control?

A:The device features a built-in RS485 communication interface, enabling integration with a host computer; local operation is performed via a touchscreen for parameter configuration and status monitoring.

Q5 What are the dimensions and weight, and is it easy to move?

A: Dimensions: 145 x 61 x 700 x 1700 mm; Weight: ≤600 kg; Equipped with casters on the bottom; Suitable only for short-distance movement on flat indoor surfaces.
