50KW AC Load Bank with 208V, 120V, 240V Multi-Voltage Support for Generator and UPS Testing

50KW AC Load Bank For 208V, 120V, 240V High Power Resistive Load Bank For Generator, UPS, And Power System Testing


The JH-RYF-50KWA208A120A240-W11K Adjustable Load Bank is a high-performance, versatile power testing tool designed for simulating various load conditions in power systems. It features an impressive 50KW power rating and supports voltage switching between AC 208V (three-phase), AC 240V (single-phase), and AC 120V (single-phase), making it ideal for testing a wide range of power equipment including generators, inverters, uninterruptible power supplies (UPS), and energy storage systems.


Multi-Voltage Support


This load bank supports three different input voltage configurations: AC 208V (three-phase), AC 240V (single-phase), and AC 120V (single-phase). The ability to switch between these voltages ensures flexibility, allowing the load bank to be used in a variety of testing scenarios, from industrial equipment testing to laboratory simulations and field operations.


Precision and Accuracy


The JH-RYF-50KWA208A120A240-W11K features high precision resistive load elements, with an accuracy of ±3%. This ensures that power measurements are accurate, making it an ideal choice for critical testing applications where precise performance data is essential for decision-making and equipment calibration.


Adjustable Power Settings


This unit provides customizable power settings for different phases (A, B, and C). Each phase can be independently loaded with the following configurations: 33W, 66W, 166W, 333W, 666W, 1666W, 3333W, 6666W. This ability to adjust each phase separately allows for both balanced and unbalanced three-phase testing, making it perfect for testing power systems with complex load demands or uneven distribution.


Cooling and Protection Systems


The load bank is equipped with a forced air cooling system, which expels hot air from the front to the back, keeping the unit at optimal operating temperatures during continuous use. Additionally, the load bank is fitted with over-voltage, over-temperature, and emergency stop protections, ensuring safe operation and preventing damage to both the load bank and the connected equipment.


Ease of Use


The unit is designed with user-friendly features, such as manual control via the main switch, which allows for straightforward operation.The real-time display shows key parameters, including voltage, current, and power, making it easy for users to monitor performance during testing. The IP20 rating ensures that the device is suitable for indoor use, providing protection against accidental contact with internal components.
