This dedicated load bank is engineered for aerospace testing applications. It delivers full rated power of 300kW at both 800V DC and 915V DC, with a minimum adjustment step of 5kW. It can also operate at reduced voltage in compliance with Ohm’s Law. Equipped with Siemens automatic control system, the unit supports touchscreen local operation and remote PC upper computer control. Cooling system adopts IP65 TEFC fully enclosed fan-cooled motors driving cast aluminum fan blades. Comprehensive protection functions are integrated, including overtemperature, air pressure, fan interlock, overcurrent, overvoltage and other safety protections.
- Working Cycle: Continuous operation.
- Load Accuracy: ±3%
- Remote Control: An external ethernet port is provided to mimic the control screen using free software for remote control using a customer provided laptop, PC, or tablet. Or Modbus RTU/RS485 is available.
- Instrumentation: Digital metering (V, A, kW) and data logging.
- Control Power: Via external 380-415V AC, 3P5W, 50Hz.
- Cooling System: Integral forced-air cooling system, bottom inlet, up outlet.
