Product Description400kW Resistive Load Bank|Dual Input Voltage|ISO9001/CE CertifiedThanks for the Peru client who placed order for 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:Product DescriptionTechnical Features1) 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.Application1) Generator set testing: validates steady-state and transient performance of diesel/gas generators2) UPS power supply inspection: evaluates load capacity and transfer characteristics of uninterruptible power supplies3) New energy system assessment: tests output stability of PV inverters and energy storage systems4) Marine power verification: meets shore-based commissioning requirements for shipboard power systems5) Data center acceptance: examines reliability of backup power systemsTechnical Features1) Pure resistive load simulates real-world power consumption2) Precise power factor setting (typically 1.0)3) Supports step-loading for dynamic response testing4) More controllable and maintainable than inductive/capacitive loads)Specification400kW Resistive Load Bank Main Specification(Customized available)Rated power400kW(resistive only)Rated voltage380V/220VAC,3P4W,connected with tin plated voltage,star-delta conversionOperate voltage380VAC,3P4W,connected with water proof quick plugPower factor1.0Load accuracy±3%Control modeLocal panel manual control(remote automatic control can be supplied)CoolingForced air cooling,horizontal air discharge,dB≤80,1mResistorNi-Cr alloy resistorProtectionOver voltage/current,short circuit,high temperature alam,low air volume alarm,emergency stopEnclosureCold rolled steel with powder coated,customized colorSize1550*1450*1380mmWeight650kgsDetail PicturesCompany ProfileCompany ProfileFounded in 2024, Yuafeng Electrics focuses on high-performance load box manufacturing and global export, and has successfully served customers in 6 countries including Canada, Kazakhstan, UAE, Tanzania, Chile and Peru. The company has passed ISO 9001 quality management system and CE certification to ensure that each device meets international safety standards.Core advantages1) Accurate testing: Resistive/resistive load box accuracy reaches ±3%, covering 0-5000kW power range2) Scenario customization: generator set testing, ship shore power verification, data center UPS aging3) Global delivery: support EXW/FOB/DDU/CIF trade terms, provide multi-language operation manuals4) Agile service: 24-hour technical response, lifelong maintenance supportFAQ1, What is the HS code for the load bank?The HS code is 90308990902, What is the delivery time?Generally 25-45 days based on the quantity and power capacity of the load bank.3, Do you accepted customized service?Yes.4, Do you accept factory inspection?Yes. 5, What's the power range of the load bank you can supply?We can supply 2kW~5000kW,5kVA~5000kVA power capacity for each single load bank.6, What's the resolution of its power adjustment?It could be 1kW/1kvar resolution. We also supply infinite - step control for the power loading.7, How to control the load bank temperature rising?The temperature will be rising during the using process. Forced air cooling system will be used to control the temperature at a reasonable level in order to make sure the load bank work continuously and not be broken.8, What control mode for the load bank can be supplied?We supply 3 control mode for the load bank control include local panel button manual control mode,local panel touch screen control and remote PC control through Modbus TCP, PLC and control software that we supplied, remote control connection terminal include RJ45, RS232 and RS485,50-100m free super 6 category net cable will be supplied.9, What are the main function for the remote PC control mode can supply?Include turn on/turn off the load bank remotely;remote load and unload function;data save and printing;the load bank can working automatically after set the loading time, power and other parameters of the load bank in the control software like 0%-25%-50% -75% -100%-110% and how much time for each of these steps. You can check the voltage,power,current,power factor and frequency. And monitor the load bank running status such as running, standby, malfunction, etc., and send out remote alarms when abnormal situations (such as over voltage, over current, overheating, etc.) occur.10, Are there detailed operation manuals and training materials?Yes,easy to operate the load bank and with detailed operation manuals and training materials, we also supply operation video for each order.
