IEC 60335-2-59 30KW Resistive Load Bank For Electrical Load To Power Source
Product information:
This resistive load is required by IEC 60335-2-59 clause 3.1.9.
A resistive load bank is a device used to apply an electrical load to a power source, such as a generator, uninterruptible power supply (UPS), or electrical system, for testing, commissioning, and maintenance purposes. It consists of a bank of resistors that emulate the electrical load that the power source would normally encounter during operation. Here are the key features and functions typically associated with a resistive load bank:
Load Simulation: The resistive load bank provides a simulated electrical load that mimics the real-world conditions that the power source will face. It does this by using resistive elements to convert electrical energy into heat, effectively drawing current from the power source. This simulated load allows for testing and evaluating the performance, capacity, and stability of the power source under different load conditions.
Load Control: A resistive load bank enables precise control over the load parameters, including the load level, power factor (leading or lagging), and load imbalance. Load control is essential for accurately simulating various operating conditions and ensuring that the power source is tested under realistic scenarios.
Power Dissipation: The resistive elements in the load bank convert electrical energy into heat, dissipating it into the surrounding environment. Adequate cooling mechanisms, such as fans, are often incorporated into the load bank design to maintain the desired operating temperature and prevent overheating of the resistors.
Load Monitoring: Resistive load banks typically include monitoring capabilities to measure and display various electrical parameters, such as voltage, current, frequency, power factor, and load imbalance. These measurements allow operators to assess the performance of the power source and ensure that it meets the desired specifications.
Portable or Stationary Design: Resistive load banks are available in both portable and stationary configurations. Portable load banks are compact and lightweight, making them easy to transport and suitable for on-site testing and troubleshooting. Stationary load banks are typically larger and designed for permanent or fixed installations in testing facilities or power system laboratories.
Safety Features: Load banks incorporate safety features to protect both the power source and the load bank itself. These features may include short-circuit protection, overvoltage protection, overcurrent protection, and thermal protection. Safety interlocks and indicators ensure that the load bank operates within safe limits and prevents any potential damage or hazards.
Load Testing Applications: Resistive load banks find applications in various industries and scenarios. They are commonly used for load testing and commissioning of generators, UPS systems, transformers, switchgear, and other power system components. Load banks are also used for periodic maintenance, performance verification, and troubleshooting of power sources to ensure their reliable operation.
Resistive load banks provide a controlled and repeatable method for testing and validating the performance of power sources. By applying a simulated electrical load, they allow for the assessment of the power source's capabilities, efficiency, voltage regulation, and overall stability under different operating conditions.

Power supply from test sample: If the power supply from the test sample is three phases, then all the GA, GB, GC and N terminals should be connected to test sample correspondingly (GA+GB+GC+N); if the power supply from the test sample is single phase, then one of the GA, GB, GC terminals plus N terminal should be connected to test sample correspondingly (such as GA+N terminals).
Power supply from mains: the power supply from mains should be three phases AC220V/60Hz, the power supply is for the control components of this load bank. Operator should remove the lower three wires from the lower three terminals, and wrap up them well. Then operator uses the power supply cord we’ve offered to connect to the mains (L1+L2+L3+PE). The load bank must be grounded reliably before use.
