Core Advantages
1) High-precision control under all operating conditions: The torque flange and fuel consumption meter both achieve a high
precision of 0.2% FS. Combined with the PID algorithm, it realizes
speed fluctuation control over a wide speed range (0-10000rpm)
(typical value <±0.1%), and seamless switching between constant
torque (0-3000rpm) and constant power (3000-10000rpm) modes,
ensuring the reliability and consistency of test data under
different operating conditions.
2) Four-quadrant energy optimization: Supports dual-mode operation of electric/generator, optimizes
energy feedback efficiency for full-condition testing needs such as
start-stop, cruise, and sprint of medium and high power drone
engines, and reduces testing energy consumption costs.
3) Flexible modular expansion: The XLE-1000 measurement and control system is compatible with
multi-channel data acquisition. Optional components such as
couplings and shock absorbers can be flexibly matched according to
the testing requirements of different models of 90kW-class engines,
adapting to diverse testing scenarios and improving system
reusability.
4) High-speed safety protection: The frequency conversion system integrates multiple protection
mechanisms for overload, overvoltage, and overheating. It
strengthens the equipment stability design for high-speed operation
scenarios of 10,000 rpm, effectively reducing the risk of equipment
failure in high-speed testing and ensuring that the testing process
is safe and controllable.
5) Low-interference and stable design: The shock absorber is precisely adapted to the 8-15Hz vibration
frequency. Combined with the high rigidity and low vibration
characteristics of the HT300 cast iron plate, it greatly reduces
external interference during high-speed operation and ensures that
the test accuracy is not affected over a wide speed range.

alloys.
3) Small and medium-sized new energy power systems testing: Supports the evaluation of energy feedback efficiency of small and
medium-sized hybrid drones, optimizes energy utilization schemes
