FAQ
1
What are the main technical specifications of the Rata X500 500kW load bank?
The Rata X500 is a 500kW resistive AC load bank, rated for test voltages of 416Vac / 208Vac. It supports both 50Hz and 60Hz frequencies and operates on a three-phase, four-wire (star-connected) system. It offers a fine load step resolution of 1kW, with total load adjustable from 1kW up to 500kW.
2
How is the load step adjustment achieved in this load bank?
The load stepping is achieved through a combination of switchable load elements with different power ratings, including 1kW, 2kW, 2kW, 5kW, 10kW, 10kW, 20kW, 50kW, 100kW, 100kW, and 200kW. These steps can be flexibly combined to achieve a minimum resolution of 1kW, enabling precise load control.
3
What are the cooling method and operating environment requirements of the X500 load bank?
The X500 uses a horizontal forced-air cooling system with an airflow capacity of 1600 CBM/min. It is designed to operate continuously in a wide ambient temperature range from -25°C to +55°C, ensuring stable performance during long-duration testing.
4
What safety protection features does the load bank provide?
To ensure safe operation, the X500 is equipped with multiple protection features, including thermal emergency shutdown, airflow switch protection, fan overload protection, and an emergency stop button. These functions can automatically or manually disconnect the load under abnormal conditions, ensuring the safety of both equipment and personnel.
5
What types of power systems is the X500 load bank suitable for testing?
The X500 load bank is suitable for testing generator sets, uninterruptible power supplies (UPS), transformers, switchgear, and other medium- and low-voltage AC power systems. It can be used to verify power output capacity, stability, transient response, and overload protection performance.
6
What is the control method of the load bank?
The X500 load bank uses a manual control method, operated via toggle switches or push buttons. The auxiliary power supply is rated at 240V, 50Hz.
7
How portable is the load bank?
The unit is designed with forklift pockets at the base, allowing for easy transportation and on-site deployment using a forklift.
8
How do voltage tolerance and load element tolerance affect the test results?
The load bank has a voltage tolerance of +5% under short-term operation and a load element tolerance of ±2.5%. These tolerance levels ensure that the load bank can provide a stable and relatively accurate load during testing, thereby guaranteeing the reliability of performance evaluation for the power equipment under test.
9
What is the significance of the rated test voltage 416Vac / 208Vac in power testing?
416Vac / 208Vac are common voltage levels used in industrial and commercial applications. The ability of the load bank to operate at these voltages means it can be directly used to test power equipment that conforms to these standards—such as generator sets and UPS systems in data centers, factories, and large commercial buildings—without the need for additional voltage transformation equipment.
10
What is the insulation test standard of the load bank?
The insulation test standard of the load bank is 600 Vac, indicating that its electrical insulation design complies with relevant safety requirements and can withstand a certain level of high-voltage testing conditions.
11
Warranty service?
3 years.
12
Do you provide installation and testing support?
Yes, Rata provides on-site testing services, including equipment installation, configuration, and data logging.
13
How many countries have you exported to?
We export to over 80 countries worldwide.
14
