400kW resistive load bank with dual input voltage(380V/220VAC) and load banks will be placed on the truck to facilitate serving different local customers. So, we designed the load bank as following shows and kindly note that your inquiry/message will be replied soon(Less than 10 minutes).

Product Description

Technical Features

1) 400kW high power capacity, meets high-load testing requirements for generators, UPS, and energy storage systems; 

2) IP54 protection rating, weatherproof design for harsh environments, forced air cooling + high-temperature resistant alloy resistors ensure continuous full-load operation without derating; 

3) Precise adjustment with 1kW minimum step resolution for more reliable test data, manual knob + LCD panel provides intuitive operation and zero-delay response. 

4) Star-delta conversion design to ensure 400kW power for both 380V and 220V input voltage.

Application

1) Generator set testing: validates steady-state and transient performance of diesel/gas generators
2) UPS power supply inspection: evaluates load capacity and transfer characteristics of uninterruptible power supplies
3) New energy system assessment: tests output stability of PV inverters and energy storage systems
4) Marine power verification: meets shore-based commissioning requirements for shipboard power systems
5) Data center acceptance: examines reliability of backup power systems

Technical Features

1) Pure resistive load simulates real-world power consumption
2) Precise power factor setting (typically 1.0)
3) Supports step-loading for dynamic response testing
4) More controllable and maintainable than inductive/capacitive loads)
