Product Description
Resistive Load Bank Offering Load Simulation Capabilities For Electrical Equipment Testing And Power System Diagnostics
Product Overview

Advanced resistive load bank designed for comprehensive electrical equipment testing and power system diagnostics with precise load simulation capabilities.

Key Features
  • Step-Adjustable Load with Precision Control: Power ratings: 100W, 200W, 200W, 500W, 1000W, 1000W, 1500W, 1500W, 1500W. Freely combinable power levels with 100W step resolution. Pure resistive load with power factor = 1. Resistance accuracy: ±3%. Stable test data output.
  • Clear Digital Display & Intuitive Operation: Digital display panel provides real-time monitoring of voltage, current, and power. Sectionalized load control via circuit breakers with emergency stop button for simple start-stop operations.
  • Reliable Forced Air Cooling: Equipped with 6 × 12038 cooling fans arranged in left-to-right airflow path for continuous heat dissipation. Supports uninterrupted 24/7 online continuous operation.
  • Multi-Layered Security Protection: Integrated overtemperature alarm, 1.1× voltage overvoltage trip protection, and emergency shutdown function. Automatic protection against abnormal operating conditions to prevent damage to both power supply and load unit.
Application Scenarios
  • AC Power Supply Factory Aging Test
    AC220V switching power supply, adapter, inverter power supply, compact UPS, and energy storage inverter: full-load and segmented aging tests
  • Backup Power Supply Performance Testing
    Small 220V generator sets; portable generator load-carrying capacity testing; output stability verification
  • New Energy-Related Tests
    Load-simulated testing of residential microinverters, energy storage converters, and small AC charging modules; output characteristic verification
  • Laboratory R&D and Teaching Experiments
    Power electronics experiments at universities and research institutes, simulating various resistive load conditions; performance baseline assessment during product development phase
Frequently Asked Questions
Can the load cabinet operate continuously at full power for extended periods?
Yes, the equipment supports 24/7 continuous operation. Ensure proper environmental ventilation, avoid blocking air inlets and outlets, and maintain ambient temperature between -10°C and 50°C in a dry environment.
How are the gears combined? What is the maximum output power?
All gears can be combined in series. Total rated power is 8 kW. Supports single gear operation or multiple gears operating simultaneously, with minimum adjustment step of 100W.
Is the auxiliary power supply the same as the test power supply?
Recommended to use separate power supplies. Auxiliary power supply provides AC 220V for fans and display control; test power supply connects to load terminals. While shared power supply is permissible, separate supplies provide greater stability during high-power testing.
Can the load cabinet only be connected to AC 220V?
Rated voltage for this model is AC 220V. Do not connect to AC voltage higher than 250V, as this may trigger overvoltage protection or damage resistor components.
