【Hot Questions(RFQ)】
Q1: What is the rated power of this air-cooled resistive load bank?
A1: Rated power can be customized from 100kW up to 5000kW.
Q2: What three-phase voltage systems does this resistive load bank support?
A2: It supports 415V Line / 230V Phase three-phase power. 400V/230V and 480V(277V phase) versions are available as customized options.
Q3: Can multiple resistive load banks be paralleled for large capacity testing?
A3: Yes. Multiple units can be synchronized and paralleled together to realize higher total load capacity for large-scale power system testing.
Q4: Can the system automatically generate test reports?
A4: Yes. The system automatically records full test data and exports editable test reports in CSV / PDF format for project acceptance and handover.
Q5: Is overseas on-site commissioning and training service available?
A5: Yes. We offer overseas on-site commissioning, operation training and long-term technical support.
Remote online commissioning is also available as an alternative solution.
Q6: What is the load adjustment step resolution?
A6: Standard load step resolution is 1kW. Finer step resolution can be configured upon customer request.
Q7: Does it support remote control via MODBUS / TCP/IP communication?
A7: Yes. MODBUS-RTU and MODBUS TCP/IP are built-in. It supports remote load setup,
real-time data acquisition and alarm monitoring.
Q8: What is the cooling method of this load bank?
A8: Air cooling is the standard configuration. Liquid cooling version is optional for high heat density applications if required.
Q9: What is the maximum continuous operating time under full rated load?
A9: It supports 24/7 continuous stable operation at full rated load.
Q10: Can it simulate dynamic load fluctuation for UPS switching and power failure tests?
A10: Yes. It supports programmable dynamic load profiles, step and ramp load variation,
to simulate power outage and UPS transfer switching scenarios.
Q11: What built-in protection functions are equipped? (overheat, overcurrent, overvoltage, emergency stop etc.)
A11: Built-in protections include over-temperature, over-current, over-voltage, under-voltage, fan failure and emergency stop.
The unit will automatically cut off the load once any alarm is triggered.
Q12: What is the delivery lead time for standard and customized models?
A12: Standard models: 4–6 weeks. Customized special voltage or modified structure models: 8–12 weeks, subject to final project specifications.
Q13: What data parameters can be recorded during testing?
A13: It records voltage, current, active power, apparent power, power factor, temperature, running time and alarm logs.
Q14: What is the working ambient temperature range for the load bank?
A14: Standard working ambient temperature: -20℃ ~ +50℃. Special low/high temperature adaptation can be customized.
Q15: What is the warranty period?
A15: 12 months warranty from the date of shipment. Lifetime paid technical support and spare parts supply are available after warranty expiry.





1. Q: What is the lead time?
A: Standard VILVA-RH load banks have a lead time of 15–25 working days. Customized models will be confirmed according to your technical requirements.
2. Q: What’s your warranty period?
A: We provide 12 months warranty for the whole machine from the date of shipment. Lifetime technical support is available for all our load banks.
3. Q: Can load banks work in parallel?
A: Yes. VILVA-RH series supports multi-unit paralleling. Multiple load banks can be connected to expand total test power for large-capacity generator, UPS and energy storage testing projects.
4. Q: Can you customize voltage / power?
A: Yes. We support custom voltage, power, control function and cabinet structure. Please share your test specifications for a customized solution.
5. Q: Do you provide on-site commissioning service?
A: We can provide remote guidance for commissioning. On-site service is available upon request; service cost will be quoted separately.
