Application Scenarios
- Precise stepped loading: resistive steps down to 1 kW resolution and inductive steps down to 1 kVAr, with total step combinations for fine control.
- Accuracy and balance: loading accuracy ≤ 3% and 3-phase unbalance ≤ 3%.
- Construction: 8020 Ni-Cr finned resistors, 3-phase inductors, Q235 powder-coated steel enclosure, forklift holes and lift lugs.
- Cooling and noise: forced-air cooling with axial fans, horizontal intake / vertical outlet, noise < 80 dB at 3 m.
- Controls & monitoring: local panel or remote PC/PLC operation; interfaces RJ45/RS232/RS485; Modbus TCP support; digital metering for voltage, current, power, power factor and frequency.
- Protections & expandability: over-temperature, low-air, phase-sequence, short-circuit, fan interlock, emergency stop; supports parallel expansion of multiple units.
3) Product value
- Validates generator performance and power-factor behavior under realistic loads, helping ensure reliable commissioning and maintenance of diesel and turbine generator sets.
- Reduces operational risk and downtime by enabling controlled, repeatable load tests for UPS, shore power, aviation power, emergency vehicles and other critical systems.
- Long expected service life (~20 years) and compliance with international/military/ship standards deliver durable, certifiable test capability.
4) Product advantages
- Industry certifications (CE, ISO9001/14001/45001, SGS) and use of reputable component brands (partners include ABB, Schneider, Siemens, Omron, Phoenix Contact).
- Flexible customization (OEM/ODM, voltages, colors, control options) and comprehensive factory documentation (test report, wiring diagram, operation manual, remote-control software).
- Strong after-sales and technical support: 12-month warranty with free maintenance for quality issues, 7×24 support, specified response and onsite-arrival windows, lifetime paid service and technical consulting.
- Robust build and continuous-duty design with precise control and multiple safety protections for dependable operation in demanding environments.
5) Application scenarios
